Connections Diagram
All the models of the EV series proximity sensors (except for M8) are provided with a built
in short-circuit protection circuit. The sensor will not therefore be damaged even if it is directly
connected to a power source. With no load connected, however, the sensor will not detect
anything even when it is connected to a power source. Connect the brown cord of the
proximity switch sensor to the ( + ) posivtive side, and the blue cord the ( – ) negative side
for NPN input.
Hints on Correct Use
■ Wiring
• Route the sensor cable separately from
the motor power cable or high tension
cables as the sensor may malfunction as a
result of noise.
• The sensor cable length should be 200m
(656ft.) or less using a cable with a conduc-
tor cross-section area equal to or greater
than that of the standard cable.
■ Effect by ambient metal
Sensors of shielded type can be flush-
mounted into metal. As for sensors of
unshielded type, however, the distance longer
than the value shown in the table below shall
be given between a sensor of unshielded
type and metal.

When mounting the sensor, be sure to use the
toothed washer suppIied as an accessory.
Tighten the washer to less than the torque
specified for each model in the table below.

■ Leakage current
With the EV series sensors, a leakage cur-
rent flows through the sensor even when the
output is turned off. For this reason, some
voltage may remain in the load connected to
the sensor, which may result in unwanted
operation or chattering, depending on the
load (Ex. Programmable logic controller). In
such a case, be sure to connect a resistor in
parallel with the load to minimize the residual
voltages at both ends of the load.
■ Relay Load
Note that the sensor's residual voltage is
3.4V. (A 12 VDC relay cannot be operated.)
■ Low load current
If the load current is less than 5mA, connect
a bleader resistor in parallel with the load so
that a current of more than 5mA flow through
the sensor.
