● Wiring
Connecting and Wiring
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.

Terminal Protection Cover (Provided)
The terminal protection cover is designed to improve safety by
maintaining the sensitivity properties of the product and by preventing
any contact with charged sections while it is being operated 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).
• Recommended outer diameter of cables is from 6 to 8 mm.
• Be sure to firmly tighten the cover in order to maintain waterproof

● Designing
Power Reset Time
The Sensor is ready to detect within 200 ms after it is turned ON. If
the Sensor and load are connected to separate power supplies, be
sure to turn ON the Sensor first.
● Wiring
Connecting and Wiring DC SSR Output Models
When using the DC SSR output model, the total of the load current 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).
● Others
Ambient Conditions (Installation Area)
The E3JM will malfunction if installed in the following places.
• Places where the E3JM is exposed to a dusty environment.
• Places where corrosive gases are produced.
• Places where the E3JM is directly exposed to water, oil, or
chemicals.
