(Mutual Interference Reduction) function, meaning it rejects crosstalk from adjacent sensors on the same line — useful on conveyor belts or multi-lane detection where units are mounted close together. The relay output switches 0 to 3 A loads directly, so you can drive a contactor or PLC input without an interposing relay. Sensing distance is 0 to 4 m when paired with the E39-R1 reflector, and the standard sensing object is an opaque 75 mm diameter target. The red LED source (660 nm) is visible during alignment, which saves time on the ladder. ## Supply and output Power supply is 24 to 240 VAC, -10% to +10%, so it runs on common plant voltages without a separate DC supply. Operation mode is Light-ON only — the output energises when the beam is made.","metaTitle":"E3JMR4M4G Omron E3JM-R4M4-G Retro-reflective Sensor, Relay O","metaDescription":"Omron E3JM-R4M4-G retro-reflective photoelectric sensor with M.S.R. function.
