Retroreflective with Mirror Surface Rejection (MSR) so polished tanks or bright packaging won't ghost a false presence. 100 mm minimum to 4 m sensing range, red LED emitter, selectable light-on/dark-on. NPN output sinks up to 100 mA; supply is 10-30V DC via the prewired 2 m cable. Response time 1 msec. ## Production status and sourcing Listed as current production. No official successor — this is the active revision. ## Mounting and wiring in the panel Rectangular body: 11 mm wide, 32 mm high, right-angle sensing face. Prewired 2 m bare-end cable. Wire NPN output to a sinking PLC input: connect the load between the output (dark/light selected) and +V supply, common to 0V. Maximum load 100 mA — indicator or relay, not a contactor coil directly. IP69K means it survives high-pressure hot washdown; stainless clamps recommended for hygienic mount.","metaTitle":"Omron E3ZM-R61 2M Retroreflective Sensor, 4m, NPN, IP69K","metaDescription":"Active Omron E3ZM-R61 2M retroreflective photoelectric sensor.
