Omron E3ZM-R61 5M Photoelectric Sensor
Omron E3ZM-R61 5M is a retro-reflective photoelectric sensor designed around a specified sensing distance from 100 mm to 4 m. A red LED establishes the optical path with the reflector, while the NPN output transfers the resulting switching state to compatible industrial control circuitry. Light-ON and Dark-ON operation allows the response to follow different machine-control sequences. The sensor runs from 10 to 30 VDC and draws up to 25 mA. A 5 m pre-wired cable extends the available electrical routing distance compared with the shorter cable version, while the response time remains 1 ms maximum. The E3ZM-R61 5M provides longer fixed connection within the retro-reflective photoelectric sensor range across Omron Sensor Products.

The Omron E3ZM-R61 5M Photoelectric Sensor provides retro-reflective sensing over a specified 100 mm to 4 m distance. Its red LED establishes the optical route toward the reflector, and changes in the returned light determine the switching state. An NPN output communicates this state to compatible PLC and machine-control circuitry. The unit operates from 10 to 30 VDC and consumes no more than 25 mA. Light-ON and Dark-ON operation enables the output sequence to match different control requirements, while response time is specified at 1 ms maximum. A 5 m pre-wired cable increases the available routing distance from the sensing position to the electrical termination point. The square body uses SUS316L, with methacrylate resin listed for the optical section.
Where an Omron retro-reflective photoelectric sensor needs the same 4 m optical span but additional cable reach, the relevant model is the E3ZM-R61. The 5 m cable changes the installation distance rather than the sensing specification, which remains 100 mm to 4 m. Its NPN output, 10 to 30 VDC supply, and 25 mA maximum consumption define the electrical arrangement, while the 1 ms response supports quick switching when the returned optical path changes. The longer cable can place the machine-side connection farther from the sensor without changing the supplied optical characteristics. For a related version with shorter 2 m fixed wiring, see E3ZM-R61 2M.
