Note: 1. When using an M18 or M30 size E2E at an ambient temperature between 70°C and 85°C (158°F and 185°F), make sure that
the E2E has a control output of 200 mA maximum.
2. When supplying 24 VAC to any of the above models, make sure that the operating ambient temperature range is –25°C to 85°C
(–13°F to 185°F).

Short-Circuit Indication
The LED dims when the load is shorted and the load output immediately turns off and remains off until the short-circuit protection is reset.
Resetting Short-Circuit Protection
Before the short-circuit protection can be reset, the short must be repaired. We recommend turning the power off before repairing the
short. If this approach is taken, no further action is required to reset the short-circuit protection.
If the short must be repaired with power on, the following resetting steps are required:
For NO sensors, the target must be removed to reset the short-circuit protection.
For NC sensors, the target must be presented then removed to reset the short-circuit protection.

INSTALLATION
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms after power
is supplied. If power supplies are connected to the Proximity Sensor
and load respectively , be sure to supply power to the Proximity Sen-
sor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned off.
Therefore, it is recommended to turn off the load before turning off
the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power sup-
ply has an insulated transformer . Do not use a DC power supply with
an auto-transformer.
Sensing Target
Metal Coating:
The sensing distances of the Proximity Sensor vary with the metal
coating on sensing targets.
WIRING
High-tension Lines
Wiring through Metal Conduit
If there is a power or high-tension line near the cord of the Proximity
Sensor, wire the cord through an independent metal conduit to pre-
vent against Proximity Sensor damage or malfunctioning.
Cable Tractive Force
Do not pull cable with the tractive forces exceeding the following.
Diameter Tractive force
4 mm dia. max. 30 N max.
4 mm dia. min. 50 N max.
MOUNTING
The Proximity Sensor must not be subjected to excessive shock
with a hammer when it is installed, or the Proximity Sensor may be
damaged or lose its water-resistance.
ENVIRONMENT
Water Resistance
Do not use the Proximity Sensor underwater, outdoors, or in the
rain.
Operating Environment
Be sure to use the Proximity Sensor within its operating ambient
temperature range and do not use the Proximity Sensor outdoors to
maintain its reliability and life expectancy. Although the Proximity
Sensor is water resistant, a cover to protect the Proximity Sensor
from water or water soluble machining oil is recommended so that
its reliability and life expectancy can be maintained.
Do not use the Proximity Sensor in an environment with chemical
gas (e.g., strong alkaline or acid gasses including nitric, chromic,
and concentrated sulfuric acid gases).

CONNECTING LOAD TO AC 2-WIRE
SENSOR
Refer to the following before using AC or DC 2-wire Proximity Sen-
sors.
Surge Protection
Although the Proximity Sensor has a surge absorption circuit, if
there is any machine that has a large surge current (e.g., a motor or
welding machine) near the Proximity Sensor, connect a surge ab-
sorber to the machine.
Leakage Current
When it i s O F F, the Proximity Sensor has leakage current. Refer to
Leakage Current Characteristics. In this case, the load is imposed
with a small voltage and the load may not be reset. Before using the
Proximity Sensor, make sure that this voltage is less than the load
reset voltage. The AC 2-wire Proximity Sensor cannot be con-
nected to any card-lift-off relay (e.g., the G2A) because contact
vibration of the relay will be caused by the leakage current and the
life of the relay will be shortened.
Countermeasures Against Leakage Current
AC 2-wire Models
Connect a bleeder resistor as the bypass for the leakage current so
that the current flowing into the load will be less than the load reset
current.
As shown in the following diagram, connect the bleeder resistor so
that the current flowing into the Proximity Sensor will be 10 mA mini-
mum and the residual voltage imposed on the load will be less than
the load reset voltage.
Load
Bleeder resistor R VAC power
supply VS
Refer to the following to calculate the bleeder resistance and the al-
lowable power of the bleeder resistor.
R VS/(10 – I) (kΩ)
P > VS2/R (mW)
P: The allowable power of the bleeder resistor. (The actual power
capacity of the bleeder resistor must be at least a few times as
large as the allowable power of the bleeder resistor.)
I: Load current (mA)
The following resistors are recommended.
100 VAC (supply voltage): A resistor with a resistance of 10 kΩ max-
imum and an allowable power of 3 W minimum
200 VAC (supply voltage): A resistor with a resistance of 20 kΩ max-
imum and an allowable power of 10 W minimum
If these resistors generate excessive heat, use a resistor with a re-
sistance of 10 kΩ maximum and an allowable power of 5 W mini-
mum at 100 V AC and a resistor with a resistance of 20 kΩ maximum
and an allowable power of 10 W minimum at 200 VAC instead.

If 100 or 200 VAC is imposed on the Proximity
Sensors, VL (i.e., the voltage imposed on the
load) will be obtained from the following.
VL = VS – (residual voltage x no. of Proximity
Sensors) (V)
Therefore, if VL is lower than the load operating
voltage, the load will not operate.
A maximum of three Proximity Sensors can be
connected in series provided that the supply
voltage is 100 V minimum.

In principle, more than two Proximity Sensors
cannot be connected in parallel.
Provided that Proximity Sensor A does not
operate with Proximity Sensor B simultaneously
and there is no need to keep the load operating
continuously, the Proximity Sensors can be
connected in parallel. In this case, however, due
to the total leakage current of the Proximity
Sensors, the load may not reset properly.
It is not possible to keep the load operating
continuously with Proximity Sensors A and B in
simultaneous operation to sense sensing objects
due to the following reason.
When Proximity Sensor A is ON, the voltage
imposed on Proximity Sensor A will drop to
approximately 10 V and the load current flows
into Proximity Sensor A, and when one of the
sensing objects is close to Proximity Sensor B,
Proximity Sensor B will not operate because the
voltage imposed on Proximity Sensor B is 10 V,
which is too low. When Proximity Sensor A is
OFF, the voltage imposed on Proximity Sensor B
will reach the supply voltage and Proximity
Sensor B will be ON. Then, Proximity Sensor A
as well as Proximity Sensor B will be OFF for
approximately 10 ms, which resets the load for
an instant. To prevent the instantaneous
resetting of the load, use a relay as shown on the
left.
