Close Range Operation
Applications
requiring 100% reading-to-reading reliability should not use MaxSonar sensors at a distance closer than 20cm1. Although most users find MaxSonar sensors to work reliably from 0 to 20-cm1 for detecting objects in many
applications, MaxBotix® Inc. does not guarantee operational reliability for objects closer than the minimum reported
distance. Because of ultrasonic physics, these sensors are unable to achieve 100% reliability at close distances.

XL-MaxSonar® - WR/WRC™ Series
XL-MaxSonar-WR/WRC Pin Out
Pin 1- Leave open (or high) for serial output on the Pin 5 output. When Pin 1 is held low the Pin 5 output sends a pulse
(instead of serial data), suitable for low noise chaining.
Pin 2- This pin outputs a pulse-width representation of range. To calculate the distance, use a scale factor of 58uS per cm.
(MB7051, MB7052, MB7053, MB7060, MB7062, MB7066)
This pin outputs the analog voltage envelope of the acoustic waveform. For the MB7070 series and MB7092 sensors, this
is a real-time always-active output (MB7070, MB7072, MB7076, MB7092, MB7150, MB7155)
Pin 3- AN-This pin outputs analog voltage with a scaling factor of (Vcc/1024) per cm. A supply of 5V yields ~4.9mV/
cm., and 3.3V yields ~3.2mV/cm. Hardware limits the maximum reported range on this output to ~700 cm at 5V and ~600
cm at 3.3V. The output is buffered and corresponds to the most recent range data.
For the 10-meter sensors (MB7051, MB7053, MB7066, MB7076) Pin 3 outputs an analog voltage with a scaling of
(Vcc/1024) per 2-cm. A supply of 5V yields ~4.9mV/2-cm., and 3.3V yields ~3.2mV/2-cm. This Analog Voltage output
steps in 2-cm increments.
Pin 4- RX- This pin is internally pulled high. If Pin-4 is left unconnected or held high, the sensor will continually measure
the range. If Pin-4 is held low the sensor will stop ranging. Bring high 20uS or more to command a range reading.
Pin 5- TX- When Pin 1 is open or held high, the Pin 5 output delivers asynchronous serial data in an RS232* format,
except the voltages are 0-Vcc. The output is an ASCII capital “R”, followed by ASCII character digits representing the
range in centimeters up to a maximum of 765 (select models) or 1068 (select models), followed by a carriage return
(ASCII 13). The baud rate is 9600, 8 bits, no parity, with one stop bit. Although the voltages of 0V to Vcc are outside the
RS232* standard, most RS232* devices have sufficient margin to read the 0V to Vcc serial data. If standard voltage level
RS232* is desired, invert, and connect an RS23* converter such as a MAX232.When Pin 1 is held low, the Pin 5 output
sends a single pulse, suitable for low noise chaining (no serial data).
*The MB7150 & MB7155 are TTL output format (inverted RS232) and follow the same ASCII data structure
V+ Operates on 3V - 5.5V. The average (and peak) current draw for 3.3V operation is 2.1mA (50mA peak) and 5V
operation is 3.4mA (100mA peak) respectively. Peak current is used during sonar pulse transmit. Please reference page 13
for minimum operating voltage verses temperature information.
GND-Return for the DC power supply. GND (& V+) must be ripple and noise free for best operation.
_______________________________________________________________________________________________________________________________________
About Ultrasonic Sensors
Our ultrasonic sensors are desired for use in air, non-contact object detection and ranging sensors that detect objects
within a defined area. These sensors are not affected by the color or other visual characteristics of the detected object.
Ultrasonic sensors use high frequency sound to detect and localize objects in a variety of environments. Ultrasonic sensors
measure the time of flight for sound that has been transmitted to and reflected back from nearby objects. Based upon the
time of flight, the sensor then outputs a range reading.
_____________________________________________________________________________________________________________________________________
Auto Sensitivity Adjustment
Each time before the XL-MaxSonar-WR takes a range reading it auto calibrates. The sensor then uses this data to range
objects. If the temperature, humidity, or applied voltage changes during sensor operation, the sensor will continue to
function normally. (The sensors do not apply compensation for the speed of sound change verses temperature to any range
readings.) If the application requires temperature compensation please look at the HRXL-MaxSonar-WR sensor line.
_______________________________________________________________________________________________________________________________________
Supply Voltage Compensation
During power up, the XL-MaxSonar-WR sensor line will calibrate itself for the supply voltage. Additionally, the sensor
will compensate if the supplied voltage gradually changes.
If the average voltage applied to the sensor changes faster than 0.5V per second, it is best to remove and reapply power to
the sensor. For best operation, the sensor requires noise free power. If the sensor is used with noise on the supplied power
or ground, the accuracy of the readings may be affected. Typically, adding a 100uF capacitor at the sensor between the V+
and GND pins will correct most power related electrical noise issues.

XL-MaxSonar® - WR/WRC™ Series
Real-time Noise Rejection
While the XL-MaxSonar-WR is designed to operate in the presence of noise, best operation is obtained when noise
strength is low and desired signal strength is high. Hence, the user is encouraged to mount the sensor in such a way that
minimizes outside acoustic noise pickup. In addition, keep the DC power to the sensor free of noise. This will let the
sensor deal with noise issues outside of the users direct control (Even so, in general, the sensor will still function well
even if these things are ignored). Users are encouraged to test the sensor in their application to verify usability.
_______________________________________________________________________________________________________________________________________
Sensor Minimum Distance
The XL-MaxSonar-WR sensors have a minimum reported distance of 20-cm1 (7.87 inches). However, the
XL-MaxSonar-WR will range and report targets to the front sensor face. Large targets closer than 20-cm1 will typically
range as 20-cm1. For the alternative housings, objects between 4-cm and 20-cm1 will typically range as 20-cm1.
Note 1: 25-cm for the MB7052, MB7092 Pipe and Compact; 50-cm for the MB7051 and MB7053 horned part.
_______________________________________________________________________________________________________________________________________
WR Exposed Materials
The exposed materials of a properly mounted MaxSonar WR standard sensor are: Aluminum (oxidized surface), PVC, &
silicone rubber (VMQ).
_______________________________________________________________________________________________________________________________________
Additional Options for Purchase
Please contact MaxBotix for any additional information regarding the options listed below at info@maxbotix.com
F-Option
In addition to the standard MaxSonar WR, MaxBotix Inc. has developed the F-Option for additional protection necessary
in a few hazardous chemical environments. Extremely corrosive gases or liquids can degrade or compromise the operation
of the sensing unit. As a result, we offer a more chemically inert seal which allows our sensors to operate in all but the
harshest of chemical environments. In addition to the chemical resistance the sensor has improved performance in wet or
dust environments.
Please Note: Our sensors are designed for operation in normal atmosphere (air). Please be aware that the speed of sound
and atmospheric attenuation may change as a result of the transmission properties of different chemical/air
mediums. Users are strongly encouraged to characterize and test the operation of the sensor in the new medium to verify
operation, and properly scale the outputted range information.
The exposed materials of a properly mounted MaxSonar WR sensor with the F-Option added are: Aluminum (oxidized
surface), PVC, & Fluorosilicone (with an additional back up FEP Teflon® seal).
Shielded Cable Attach Option
For simple integration of our sensors into end-user applications, MaxBotix has developed the Shielded Cable Attach
Option to create a completely IP67 rated MaxSonar-WR sensor. The standard Shielded Cable Attach Option uses 3 feet of
the MaxSonar MB7954 Shielded Cable (MB7984 when attached by MaxBotix) with an epoxy filled cap to fully protect
the pin-out of the MaxSonar sensor. Additional cable length can be specified and purchased using part number MB7984.
P-Option
The P-Option is a Parylene coating applied to the surface of the aluminum transducer. This helps to improve the corrosion
resistance of the aluminum transducer. The exposed materials of a properly mounted MaxSonar WR sensor with the POption added are: Parylene, PVC, & silicone rubber (VMQ). The F-Option can be purchased with the P-Option.

XL-MaxSonar® - WR/WRC™ Series
Sensor Descriptions
Base Sensor (MB7060, MB7070 & MB7155)
The MB7060, MB7070 & MB7155 are the base models of the XL-MaxSonar-WR sensor line. These sensors are recommended
for general purpose usage. All other sensors in this series are based off these sensor models. The additional features are
mentioned in their respective sections below.
_______________________________________________________________________________________________________________________________________
XL-MaxSonar-WR1 (MB7062 and MB7072)
The XL-MaxSonar-WR1 sensors feature a 3 reading stability filter that ranges to the first detectable target. Filtering is available
on Pin3 (AN) and Pin 5 (TX). Filtering is not applied to the output on Pin 2 (PW). This filter requires that
3 consecutive range readings are within 1cm of each other to be considered a valid range reading. If the range readings are
outside 1-cm, the sensor discards the range reading set and reports the last valid range reading. This sensor does not view
maximum range as a valid range, and will not report 765 when no target is detected. If this sensor does not detect a target for 1
hour, the sensor will go into fail-safe and report 000.
_______________________________________________________________________________________________________________________________________
XL-MaxSonar-WRL (MB7066 and MB7076)
The XL-MaxSonar-WRL will report a maximum distance of 10 meters for large targets.
_______________________________________________________________________________________________________________________________________
XL-MaxSonar-WRM (MB7052, MB7092 & MB7150)
The MB7052, MB7092 & MB7150 sensors prioritize large targets over both small targets and noise. These sensors report the
target that gives the largest acoustic reflection. This stands in contrast to other units such as the MB7060 which are designed to
report the distance to the first detectable target. If the largest target is removed from the field of view, the MB7052, MB7092 &
MB7150 will switch to the target that gives the next largest detectable return.
When targets are of similar amplitude reflections, preference is given to the closer target. The sensor expects to see a target by
7.56 meters. If no target is found, the sensor will increase in sensitivity until a target is found, or until no targets can be found.
In addition to the most-likely filtering, the MB7052, MB7092 & MB7150 come equipped with a three-reading filter and reading
hold which requires three consecutive range readings within 1cm of the most recent reading to be considered a valid range
reading. If readings are found to be outside 1cm, or no target can be found by the sensor, then the sensor will report the last
valid range reading. Upon power-up the sensor will default to reporting 7.65 meters unit a valid range reading is found.
The last reading hold is designed for users operating in environments with intermittent high noise who desire to poll the
MB7052, MB7092 & MB7150 at intermittent times. This allows the sensor to report the previously valid reading until the
sensor’s environment improves. If no valid range reading is found for ~1.5 hours, the sensor will send a fail-safe output “000”
on all interfaces.
_______________________________________________________________________________________________________________________________________
XL-MaxSonar-WRML (MB7051)
The MB7051 includes all the features of the MB7052 with a maximum distance of 10 meters which provides a very robust long
range sensing solution. The MB7051 is ideal for applications requiring small or soft target detection at longer ranges than our
previously mentioned XL-MaxSonar-WR sensors.
The MB7051 has improved sensitivity to objects with the addition of a horn extension. This improvement results in the sensor
detecting objects of similar size about 2.5 times further in comparison to the MB7066 sensor. The detection patterns of each are
shown in the beam pattern section of the datasheet.
_______________________________________________________________________________________________________________________________________
XL-MaxSonar-WRML1 (MB7053)
The MB7053 is based on the MB7051 but removes the three reading stability filter. This prevents the sensor from entering a fail
-safe mode where it reports 000. It also allows the MB7053 to respond to large changes in range more quickly than the
MB7051.

1 Our
standard sensors provide the range to the first target they detect. Our most-likely filter allows our sensors to continue looking for larger targets. This way
they only give you the range to the target with the largest return of sound as seen by the sensor. Note that while this will often be the largest target in an
environment, there are times when small targets will reflect more sound to the sensor than larger targets
2
Higher gain and other sensitivity adjustments allows better performance to soft targets such as grain.

About Package Types
The XL-MaxSonar-WR sensor line is available in a variety of packages for applications with specific mounting requirements. The full
horn package provides peak accuracy and sensitivity in this sensor line. It is recommended that testing is completed to ensure that the
selected sensor will operate as desired in your application.
_______________________________________________________________________________________________________________________________________
Performance Changes when Selecting a Compact, Pipe or Ultra-Compact Package
When selecting a XL-MaxSonar-WR without the full horn the sensor will experience the following performance changes:
• The sensor will have a wider beam shape for the first meter.
• The sensor may have a dead zone from 0-6-cm.
• The sensor may be less accurate by an additional +/- 0.5%.
• The sensor may have worse performance to small or soft targets.
• The sensor may experience decreased noise immunity when ranging to small, soft, angled, or distant targets.
• The maximum effective range is 645-cm, the sensor will still report 765 as a “no detection” output if a target is not found.

XL-MaxSonar-WR Sensor Operating Modes
Independent Sensor Operation
The XL-MaxSonar-WR sensors are designed to operate in a single sensor environment. Free-run is the default mode of
operation for all of the MaxBotix Inc., sensors. The XL-MaxSonar-WR sensors have three separate outputs that update the
range data simultaneously: Analog Voltage, Pulse Width1, and RS232 Serial. Below are diagrams on how to connect the
sensor for each of the three outputs. Note 1 - select models output an Analog Envelope for end user processing (MB707X sensors and MB7092)
Using Multiple Sensors in a Single System
When using multiple ultrasonic sensors in a single system, there can be interference (cross-talk) from the other sensors.
MaxBotix Inc., has engineered a solution to this problem for the XL-MaxSonar-WR sensors. The solution is referred to as
chaining. We have 3 methods of chaining that work well to avoid the issue of cross-talk.
The first method is AN Output Commanded Loop. The first sensor will range, then trigger the next sensor to range and so
on for all the sensors in the array. Once the last sensor has ranged, the array stops until the first sensor is triggered to range
again. Below is a diagram on how to set this up.
The next method is AN Output Constantly Looping. The first sensor will range, then trigger the next sensor to range and
so on for all the sensor in the array. Once the last sensor has ranged, it will trigger the first sensor in the array to range
again and will continue this loop indefinitely. Below is a diagram on how to set this up.
The final method is AN Output Simultaneous Operation. This method does not work in all applications and is sensitive to
how the other sensors in the array are physically positioned in comparison to each other. Testing is recommend to verify
this method will work for your application. All the sensors RX pins are connected together and triggered at the same time
causing all the sensor to take a range reading at the same time. Once the range reading is complete, the sensors stop
ranging until triggered next time. Below is a diagram on how to set this up.

Sensor Free-Run Timing
Sensor Timing Diagrams Continued
Timing Description
175mS after power-up, the XL-MaxSonar-WR is ready to begin ranging. If Pin-4 is left open or held high (20uS or
greater), the sensor will take a range reading. The XL-MaxSonar-WR checks Pin-4 at the end of every cycle. Range data
can be acquired once every period. Each period starts by Pin-4 being high or open, after which the XL-MaxSonar-WR
calibrates and calculates for 20.5mS, and after which, the 42KHz waves are sent. The sensor then determines the range to
the target. Next the analog voltage is set. The sensors with a pulse width (PW), Pin 2 is set high for a length of time 1. Then
serial data is sent1. The most accurate range output on the XL-MaxSonar-WR sensors is the PW output.
Note 1: Reference the timing specifications on page 12 for the exact times.
Sensors with the analog envelope output (MB7070 series and MB7092, MB7150, MB7155), Pin-2 will show the real-time
signal return information of the Analog Waveform.

XL-MaxSonar® - WR/WRC™ Series
Attenuation of Ultrasound
Attenuation, specifically absorption of sound through the air, restricts the maximum range of ultrasonic rangefinders. As
sound waves travel through the air, that air absorbs some of their energy. High frequency sounds like ultrasound are often
attenuated more quickly than lower frequency sounds. In addition to frequency, relative humidity also affect attenuation.
Warm air masses with low relative humidity will typically attenuate sound waves faster. As such performance of
ultrasonic devices may be limited at low relative humidity, especially when trying to detect targets at longer ranges.
Background Information Regarding our Beam Patterns

detection pattern shown in this datasheet. This allows end users to select the part number that

For each part number, the four patterns (A, B, C, and D) represent the detection zone for a given
target size. Each beam pattern shown is determined by the sensor’s part number and target size.
The actual beam angle changes over the full range. Use the beam pattern for a specific target at any given distance to
calculate the beam angle for that target at the specific distance. Generally, smaller targets are detected over a narrower
beam angle and a shorter distance. Larger targets are detected over a wider beam angle and a longer range.

D 11-inch wide board 4ft in length moved left to right with the
board parallel to the front sensor face. This shows the sensor’s
range capability.
Corner Reflectors
Sometimes when using an ultrasonic sensor, users experience detection of unwanted objects that appear outside the
expected beam pattern. These types of detections are the result of reflectors present in the environment. Corner reflectors
can be surprisingly small, yet present a large reflection back to the sensor. Certain objects are prone to causing corner
reflections. One of the most common corner reflectors is two flat surfaces joining together to create a 90° angle. A halfcircle also acts as a similar reflector. You can learn more about corner reflectors in our Cube Corner Reflectors article.

Frequently Asked Questions about Our Sensors
We receive many questions about our products and services. This resource offers answers to common inquiries
we receive about our product lines and their application.
Fully Calibrated Beam Patterns
All of our sensors are factory calibrated to provide consistent beam patterns, detection zones, to fit into a wide
variety of applications. In our product lines, each model number comes with a different beam pattern that reflects
the sensitivity and the detection zone of how it sees a target. Additionally, we strive to maintain consistency between our finished products, and you will see little to no deviation between sensors of the same model. This allows you to have confidence in your final application when using multiple sensors.
Understanding Range Readings
The success of an application may hinge upon knowing the exact location of a target. However, a sensor may
report one meter even if the target is not exactly one meter away from the sensor. Sensor specifications, such as
resolution, precision, and accuracy, help you to understand sensor performance.
How to Use Multiple Ultrasonic Sensors
This guide covers three ways to run your sensors in a Multiple Sensor environment and issues you may face.
Contact us now with any questions at sales@maxbotix.com or call +1-218-454-0766.
Please call during our preferred business hours of 8:00 am – 4:30 pm EST on Monday through Thursday and 8:00 am –
