Note: 1. Mutual Interference Prevention: When mounting Sensors with the same diameter and cable length in parallel, set the DIP switch to modes that differ by 1 m
in cable length. Specifications, however, may not be sufficiently met, so always check operation before actual application. This method cannot be used for
the E2C-C20MA.
2. When using the E2C-CR5B + E2C-AM4A (or AK4A), set all the pins on the Amplifier Unit DIP switch to the left.

Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
Mutual interference can be prevented by using the cable length
compensation switch, but doing so will also change coil
characteristics. Specifications such as temperature specifications
and sensing distance, may not be sufficiently met, so always check
operation before actual application.

General Precautions
For precautions on individual products, refer to the Safety Precautions in individual product information.
WARNING
These products cannot be used in safety devices for
presses or other safety devices used to protect human

These products are designed for use in applications for
sensing workpieces and workers that do not affect safety.
Precautions for Safe Use
To ensure safety, always observe the following precautions.
●Wiring Considerations
Item
Power Supply Voltage
Do not use a voltage that exceeds the operating voltage range. Applying a voltage that is
higher than the operating voltage range, or using an AC power supply (100 VAC or higher)
for a Sensor that requires a DC power supply
may cause explosion or burning.

• The influence within a DC magnetic field is 20 mT* max. Do not use the Sensor at a level higher than 20 mT.
• Sudden changes in the DC magnetic field may cause malfunction. Do not use the Sensor for applications that involve turning a
DC electromagnet ON and OFF.
• Do not place a transceiver near the Sensor or its wiring. Doing so may cause malfunction.

Sensing distance X (mm)
In general, if the object is smaller
than the standard sensing
object, the sensing distance
decreases.
• Design the setup for an object
size that is the same or greater
than the standard sensing
object size from the graphs
showing the sensing object
size and sensing distance.
• When the size of the standard
sensing object is the same or
less than the size of the
standard sensing object,
select a sensing distance with
sufficient leeway.
• The thickness of ferrous metals
(iron, nickel, etc.) must be 1 mm
or greater.
• When the coating thickness is
0.01 mm or less, a sensing
distance equivalent to a
magnetic body can be obtained.
When the coating is extremely
thin and is not conductive, such
as a vacuum deposited film,
detection is not possible.
Sensing distance X (mm)
Thickness of Sensing Object
The sensing distance varies greatly depending on the material of the
sensing object. Study the engineering data for the influence of
sensing object material and size and select a distance with sufficient
leeway.

Mutual Interference
• Mutual interference refers to a state where a Sensor is affected by
magnetism (or static capacitance) from an adjacent Sensor and the
output is unstable.
• One means of avoiding interference when mounting Proximity
Sensors close together is to alternate Sensors with different
frequencies. The model tables indicate whether different
frequencies are available. Please refer to the tables.
• When Proximity Sensors with the same frequency are mounted
together in a line or face-to-face, they must be separated by a
minimum distance. For details, refer to Mutual Interference in the
Safety Precautions for individual Sensors.
Power Reset Time
A Sensor is ready for detection within 100 ms after turning ON the
power. If the load and Sensor are connected to separate power
supplies, design the system so that the Sensor power turns ON first.

Proximity Sensors Technical Guide
Turning OFF the Power
An output pulse may be generated when the power is turned OFF, so
design the system so that the load or load line power turns OFF first.
Influence of Surrounding Metal
Countermeasures for Leakage Current (Examples)
AC 2-Wire Sensors
Connect a bleeder resistor to bypass the leakage current flowing in
the load so that the current flowing through the load is less than the
load reset current.
The existence of a metal object other than the sensing object near the
sensing surface of the Proximity Sensor will affect detection performance, increase the apparent operating distance, degrade temperature characteristics, and cause reset failures. For details, refer to the
influence of surrounding metal table in Safety Precautions for individual Sensors.
The values in the table are for the nuts provided with the Sensors.
Changing the nut material will change the influence of the surrounding
metal.
Power Transformers
Be sure to use an insulated transformer for a DC power supply. Do
not use an auto-transformer (single-coil transformer).
Precautions for AC 2-Wire/DC 2-Wire Sensors
Surge Protection
Although the Proximity Sensor has a surge absorption circuit, if there
is a device (motor, welder, etc.) that causes large surges near the
Proximity Sensor, insert a surge absorber near the source of the
surges.
Influence of Leakage Current
Even when the Proximity Sensor is OFF, a small amount of current
runs through the circuit as leakage current.
For this reason, a small current may remain in the load (residual
voltage in the load) and cause load reset failures. Verify that this
voltage is lower than the load reset voltage (the leakage current is
less than the load reset current) before using the Sensor.
Using an Electronic Device as the Load for an AC 2-Wire
Sensor
When using an electronic device, such as a Timer, some types of
devices use AC half-wave rectification. When a Proximity Sensor is
connected to a device using AC half-wave rectification, only AC halfwave power will be supplied to the Sensor. This will cause the Sensor
operation to be unstable. Also, do not use a Proximity Sensor to turn
the power supply ON and OFF for electronic devices that use DC halfwave rectification. In such a case, use a relay to turn the power supply
ON and OFF, and check the system for operating stability after
connecting it.
Examples of Timers that Use AC Half-wave Rectification
Timers: H3Y, H3YN, H3RN, H3CA-8, RD2P, and H3CR (-A, -A8, -AP,
-F, -G)
http://www.ia.omron.com/
When using an AC 2-Wire Sensor, connect a bleeder
resistor so that the Proximity Sensor current is at least 10
mA, and the residual load voltage when the Proximity
Sensor is OFF is less than the load reset voltage.

Loads with Large Inrush Current
Loads, such as lamps or motors, that cause a large inrush current* will
weaken or damage the switching element. In this situation, use a
relay.
• While pressing the Amplifier Unit in the direction of (3), lift the fiber
plug in the direction of (4) for easy removal without a screwdriver.

●Mounting
Mounting the Sensor
(4)
When mounting a Sensor, do not tap it with a hammer or otherwise
subject it to excessive shock. This will weaken water resistance and
may damage the Sensor. If the Sensor is being secured with bolts,
observe the allowable tightening torque. Some models require the
use of toothed washers.
For details, refer to the mounting precautions in Precautions for
Correct Use in individual product information.
DIN Track (3)
Set Distance
The sensing distance may vary due to fluctuations in temperature and
voltage. When mounting the Sensor, it is recommend that installation
be based on the set distance.
Mounting/Removing Using DIN Track
(Example for E2CY)
(1)Insert the front of the Sensor into the special Mounting Bracket
(included) or DIN Track.
(2)Press the rear of the Sensor into the special Mounting Bracket or
DIN Track.

For the above Proximity Sensors, the voltage VL that can be applied to the
load when ON is VL = VS - (Output residual voltage × Number of Sensors), for
both 100 VAC and 200 VAC.
The load will not operate unless VL is higher than the load operating voltage.
This must be verified before use.
When using two or more Sensors in series with an AND circuit, the limit is three
Sensors. (Be careful of the VS value in the diagram at left.)

A parallel connection can be used if A and B will not be operated simultaneously and there is no need to hold the load. The leakage current, however,

If A and B will be operated simultaneously and the load is held, a parallel connection is not possible.
If A and B operate simultaneously and the load is held, the voltages of both A
and B will fall to about 10 V when A turns ON, and the load current will flow
through A causing random operation. When the sensing object approaches B,
the voltage of both terminals of B is too low at 10 V and the switching element
of B will not operate. When A turns OFF again, the voltages of both A and B
rise to the power supply voltage and B is finally able to turn ON.
During this period, there are times when A and B both turn OFF (approximately
10 ms) and the loads are momentarily restored. In cases where the load is to
be held in this way, use a relay as shown in the diagram at left.
Note: When AND/OR connections are used with Proximity Sensors, the effects of erroneous pulses or leakage current may prevent use. Verify that there are no
problems before use.

Extending Cable Length
The cable of a Built-in Amplifier Sensor can be extended to a
maximum length of 200 m with each of the standard cables
(excluding some models).
