Product details

Retro-reflective without M.S.R. — what that means on the line

The Omron E3T-SR41 2M is a retro-reflective photoelectric sensor from the E3T family, explicitly built without the M.S.R. (mutual interference suppression) function. On a packaging or material-handling line where two sensors face each other across a conveyor, the absence of M.S.R. means the emitter and receiver must be aligned so the beam from one does not trigger the other — or you space them far enough apart that the optical crosstalk stays below the switching threshold. For a single-sensor retro-reflective installation (sensor pointing at a reflector), M.S.R. is irrelevant; the part works fine as a standard opposed-mode sensor with a reflector.

Frequently asked questions

What does M.S.R. function mean on the Omron E3T-SR41 2M?

M.S.R. stands for mutual interference suppression. On the E3T-SR41 2M, this function is absent, so the sensor does not include circuitry to filter out light from another nearby sensor of the same type. In installations where multiple retro-reflective sensors operate in close proximity, the lack of M.S.R. means you must manage the optical separation manually — either by angling the sensor-reflector pairs so their beams do not overlap, or by increasing the physical distance between sensor pairs.

Is the E3T-SR41 2M a retro-reflective photoelectric sensor?

Yes, the E3T-SR41 2M is a retro-reflective photoelectric sensor. It requires a reflector mounted opposite the sensor; the sensor emits a beam that bounces off the reflector and returns to the receiver. When an object breaks the beam, the output switches. This configuration is common on conveyor lines for detecting opaque objects passing through the sensing path.
