Switch Selection

Connecting and Wiring

Recommended outer diameter of cables is from 6 to 8 dia.

Be sure to firmly tighten the cover in order to maintain waterproof

and dustproof properties.

Cable End Treatment

Adjust the four wires to the same length when the Ta output is to

be used only. If both the Ta and Tb outputs are to be used, treat

them as shown in the following diagram.

Recommended Crimp Terminal Dimensions

(Unit: mm)

Note: Use terminals with insulation tube (recommended crimp terminal: 1.25

to 3.5).

Terminal Protection Cover (Accessory)

The terminal protection cover is designed to improve safety by

maintaining the sensitivity properties of the product and by pre-

venting any contact with charged sections while it is being oper-

ated with the mode set to the timer mode. Mount the product as

shown in the following diagram (mount the Through-beam Model

on the Receiver side).

Output Relay Contact

If a load, such as contactor or valve is used that may produce arc

when it is turned OFF, the NC (or NO) side may turn ON before

the NO (or NC) side is turned OFF. When using both the NC and

NO outputs, use an arc killer.

Connecting and Wiring DC SSR Output Models

When using the DC SSR output model, the total of the load cur-

rent for the Light-ON output (NO) and that for the Dark-ON (NC)

should be 100 mA max. If the total exceeds 100 mA, the load

short-circuit protection function will be activated (this function will

be reset when the power of the Photoelectric Sensor is turned

OFF ).
