SMART Position Sensor,
35 mm, 75 mm and 225 mm
Linear Configurations
Superior Measurement. Accurate. Reliable. Thinking.
DESCRIPTION
The SMART Position Sensor is one of the most durable,
adaptable, and lightweight linear position sensors available in the
industry, enabling highly accurate motion control and improving
operation efficiency and safety. Its simple, non-contact design
eliminates mechanical failure mechanisms, reducing wear and
tear, improving reliability and durability, and minimizing downtime.
The SMART Position Sensor is a non-contacting sensing solution
for absolute position sensing with enhanced accuracy. It senses
the position of a magnet relative to the sensor in one of three
available sensing ranges:
• 0 mm to 35 mm [0 in to 1.38 in]
• 0 mm to 75 mm [0 in to 2.95 in]
• 0 mm to 225 mm [0 in to 8.86 in]
(magnetoresistive) sensors to accurately and reliably determine
the position of a magnet attached to a moving object so that the
object’s position can be determined or controlled.
The MR array measures the output of the MR sensors mounted
along the magnet’s direction of travel. The output and the MR
sensor sequence determine the nearest pair of MR sensors to
the center of the magnet location. The output of these two MR
sensors is then used to determine the position of the magnet
between them.
With this sensor, Honeywell has utilized MR technology through
the ASIC at a level never before accomplished.
These sensors uses a patented combination of an ASIC
(Application-Specific Integrated Circuit) and an array of MR
The SMART Position Sensor is available in both analog output
(35 mm, 75 mm and 225 mm configurations) and digital output
(225 mm configuration only) for use in control systems requiring
an RS232-type interface with a 57.6 kbits/s baud rate.
FEATURES AND BENEFITS
• Reliable, durable: Non-contact design reduces wear and tear,
improving reliability and durability, and minimizing downtime
Easy to install: Installation takes four simple steps
(1: position sensor; 2: drill holes; 3: mount sensor; 4: locate
magnet actuator/make electrical connection) vs. up to 14 steps
some competitive products require, simplifying installation and
reducing set-up costs
• Rugged: As there are no moving parts within the sensor,
Honeywell utilizes unique packaging materials that make
the sensor more resistant to vibration, shock, and extreme
temperatures
Flexible: Air gap of up to 8,5 ±1,0 mm [0.334 ±0.039 in]
between sensor and magnet expands application opportunities;
variety of output options (analog standard and other RS232type baud rates) are available, expanding application
opportunities
Cost effective: Adaptable, non-contacting design allows
customers to eliminate unnecessary connections for
installation, thereby reducing installation steps, installation time,
and components
• Accurate: 35 mm configuration accurately measures values
down to 0,04 mm [0.0016 in], 75 mm configuration accurately
measures values down to 0,05 mm [0.002 in], while 225 mm
configuration accurately measures value down to 0,14 mm
[0.0055 in] (analog) and 0,0035 mm [0.000137 in] (digital)
Adaptable: Electronics on board allow for flexible packaging
and component compatibility with existing systems
Lightweight: More than 50% lighter in weight than LVDT
(Linear Variable Differential Transformer) technology
• Simplifies design-in: Easy-to-configure sensor array fits
virtually any linear movement path
Self-diagnostics feature: Can reduce equipment downtime by
providing predictive maintenance input
• Combined patented MR sensor and ASIC technology:
Provides enhanced differentiation and performance
• IP67 and IP69K sealing: allow use in many harsh applications
• Qualified for automotive grade EMI/EMC specification:
Provides protection against environmental frequencies (35 mm
configuration only)
• RoHS-compliant materials: Meet Directive 2002/95/EC

POTENTIAL APPLICATIONS
(Applies to all configurations except where noted.)
INDUSTRIAL
AEROSPACE
• Valve position: May be used to monitor valve position so the
• Aircraft actuators: May be used to control actuator position on
desired amount of liquid is delivered based on the position of
multiple applications in the aircraft, helping to regulate airflow to
the valve that is opening/closing, and how long open/closed
engines and environmental systems.
(e.g., bottling machines, food/chemical processing, water
handling equipment, etc.).
• Material handling: May be used on a lifting device that moves
cartons from one conveyor belt to another.
• Plastic molding: May be used for injection positioning.
• Cutting and slitting: May be used in paper mills to accurately
control the location of the slitter before it cuts.
• Wafer handling: May be used to monitor if parts are properly
placed.
• CNC machines: May be used to monitor tool depth and
direction of travel.
TRANSPORTATION
• Engine transmissions: May be used for gear shift position for
trucks (35 mm configuration only).
• Passenger bus level position: May be used for passenger
bus leveling to simplify access for passengers and luggage.
• Truck-mounted crane outrigger position: May be used to
determine that the outriggers are fully deployed before the
lifting of objects can begin.
• Heavy equipment attachment identification: May be used
to sense which attachments are being deployed onto heavy
equipment by the strategic placement of the magnet to the
sensor. The corresponding output indicates to the operator and
control system which attachment is connected.
• Hydraulic cylinders: May be used on non-ferrous hydraulic
cylinders for non-contact stroke position (225 mm configuration
only).
• Marine motors: May be used for trim position on inboard/
outboard motors for enhanced durability and performance.
