OMRON E3JK-RR12-C Photoelectric Sensor | Retro-Reflective, 12m, AC/DC, Relay Output, Built-in Timer

OMRON E3JK-RR12-C sensor specifications. Retro-reflective photoelectric sensor, 12m range, 12-240V AC/DC, 2 SPDT relay outputs, built-in ON/OFF timer.

Product Overview

The OMRON E3JK-RR12-C is a versatile retro-reflective photoelectric sensor designed for long-range object detection. It features a built-in power supply capable of operating on a wide range of AC or DC voltages, two independent SPDT relay outputs, and an integrated ON/OFF delay timer. The sensor uses a reflector for detection and is housed in a compact, rugged enclosure suitable for industrial environments.

Applications

Conveyor line object detection and counting
Door and gate control
Packaging machine presence sensing
Material handling and storage systems
Long-range presence detection in warehouses and factories

Important Notes

A separate retro-reflector (e.g., OMRON E39-R1, E39-R2) is required for operation.
The two relay outputs can be used independently, for example, one for immediate action and one for delayed action.
The timer function is set via a potentiometer on the sensor body.
The universal power supply allows direct connection to most industrial control voltages without a separate power adapter.
For optimal performance, ensure the reflector is aligned correctly and kept clean.
