Output Relay Contact
If E3JM is connected to a load with contacts that spark when the load is turned OFF (e.g., a contactor or valve), the normally-closed side may be
turned ON before the normally-open side is turned OFF or vice-versa. If both normally-open output and normally-closed output are used
simultaneously, apply an surge suppressor to the load.
Refer to OMRON’s PCB Relays Catalog (X33) for typical examples of surge suppressors.

● Wiring
Connecting and Wiring
● Others
Terminal Protection Cover (Provided)
• We recommend connecting a cable with a conductor cross-section
of 0.3 mm2 and an outer diameter of 6 to 8 mm.
• Be sure to firmly tighten the cover in order to maintain waterproof
and dustproof properties. The screw size of the conduit sockets is
shown in the following table.
Model
E3JM-@
Conduit socket thread size
PF1/2
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).
• 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).
