WIRING DIAGRAM SENSING AREA DIAGRAMS (typical example)

The load can be connected to either of the power supplies. However,we recommend connecting the load to the non-earthed side to preventshort-circuiting of the power supply if a ground fault caused bydamage to the proximity sensor occurs.

PRECAUTIONS

MountingBe sure to use toothed washers (provided) when mounting the

proximity sensors, and tighten the sensor to a tightening torque

of 30N-m.

Influence of surrounding metalMetal other than the target object surrounding the sensor may

influence operating characteristics. Maintain the following space

between the sensor and surrounding metal:

Shaded areas indicate surrounding metal other than the targetobject.

A: Dimension to tip (sensing face) of proximity sensor frommounting surface

B: Dimension to front iron plate from tip (sensing face) of prox-imity sensor

C: Dimension to front iron plate of proximity switch when A=0

Mutual interference preventionWhen mounting proximity sensors in parallel or facing eachother, mutual interference may cause the sensor to malfunction.

Maintain at least the spaces indicated in the figures below.

Indicator lampWhen a proximity sensor is used for a long period under high

temperature, LED deterioration will result in the indication dar-

kening, and finally the lamp will no longer light. This, however,

does not affect output operation.

Differential travelWhen the proximity sensor is used at high temperature, the

differential travel is less than when the sensor is used in normal

room temperature.

Pay attention to this when you install the sensor.

Connection to power supply and loadBe sure to connect the proximity sensor to the power supply via

the load. If the sensor is connected directly to the power supply,

the sensor will become damaged. Also, output is not subject to

polarity, and so the load can be connected to either power

supply. However, we recommend connecting the load to the

non-earthed side to prevent short-circuiting of the power supply

if a ground fault caused by damage to the proximity sensor oc-

curs.

Operation at power ONAfter the power is turned ON, it takes 100ms or less until the

proximity sensor is ready for sensing.

When the load and the proximity sensor use different power

supplies, be sure to turn the proximity sensor ON before turning

the load ON.

Influence of leakage current

Minimal current flows as leakage current for operating the cir-

cuits even when the proximity sensor is OFF.

Take sufficient care when restoring connected loads.

Minimum cord bending radius (R)The minimum bending radius (R) of the cord is 3 times cord di-

ameter, take care not to excessively bend the cord beyond this

radius. Also, do not excessively bend the cord within 30mm of

the cord lead-in port.

ProtectionThis proximity sensor is not a water-proof structure. Do not use

it in environments where it will be splashed by water or oil, or

subject to steam.

Temperature rangeDo not use proximity sensors continuously in a surrounding

temperature of over 100C.
