Design
Load Relay Contact
If a load is used that will spark when it is turned OFF (e.g. a
contactor or valve), the usually closed side may be turned ON
before the usually open side is turned OFF or vice versa. If
both usually open output and usually closed output are used
simultaneously, apply an surge suppressor to the load. (Refer
to OMRON's "Switch/Relay/Connector (PCB Product) Cata-
log" for typical examples of surge suppressors.
Wiring Considerations
Connection/Wiring
The E3G has load short-circuit protection. If load short-circuit
or like has occurred, the output turns OFF. Therefore, recheck
the wiring and switch power on again. This resets the short-
circuit protection circuit. Load short-circuit protection is acti-
vated when a current of 2 times or more of the rated load cur-
rent flows. When using an L load, use the one the inrush
current of which is less than 1.2 times of the rated load cur-
rent.
Mounting
• If Sensors are mounted face-to-face, ensure that no optical
• Be sure to install the Sensor carefully so that the directional
• Do not strike the Photoelectric Sensor with a hammer or any
• Use M4 screws for Sensor installation.
• For case installation, tighten it to the torque of 1.2 Nm max.
Water Resistance
Tighten the operation cover screws and terminal block cover
screws to a torque of 0.3 to 0.5 Nm in order to ensure water
