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.

Note: The switch for the operating mode is the same as that for
models without a timer.
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 ).
