Omron E3JM-R4M4-G Photoelectric Sensor, Retro-reflective, 4m Range, Relay Output, 12-240VDC/24-240VAC
Description
The Omron E3JM-R4M4-G is a robust retro-reflective photoelectric sensor from the E3JM series designed for industrial automation applications. It features a versatile built-in power supply accommodating both AC (24–240V) and DC (12–240V) voltages, offering flexibility in wiring. With a 4-meter sensing distance, this sensor utilizes red LED light and M.S.R. (Mirror Surface Rejection) technology to reliably detect opaque objects, even with reflective surfaces, while minimizing false triggers. It features a user-selectable Light-ON/Dark-ON operation mode and provides a reliable SPDT relay output (3A, 250VAC). The unit comes in a durable ABS case with an IP66 rating for protection against harsh industrial environments, featuring a convenient terminal block for easy installation
