Omron E3Z-R61 5M Photoelectric Sensor
Omron E3Z-R61 5M is a retro-reflective photoelectric sensor with an M.S.R. function and a specified sensing range from 100 mm to 4 m. Its 670 nm red LED provides the optical source directed toward the reflector, while the NPN output communicates the switching state to compatible PLC and machine-control circuitry. Selectable Light-ON and Dark-ON operation supports different switching requirements. The sensor operates from 12 to 24 VDC and includes a 5 m pre-wired cable for extended electrical wiring. Current consumption is specified at 30 mA maximum, while response time is 1 ms maximum. Within the E3Z Series, the E3Z-R61 5M provides longer fixed wiring within the 4 m retro-reflective sensor range across Omron Sensor Products.

The Omron E3Z-R61 5M Photoelectric Sensor uses retro-reflective sensing with an M.S.R. function across a specified range from 100 mm to 4 m. A 670 nm red LED supplies the optical source directed toward the reflector, while the NPN output communicates the switching state to compatible PLC and machine-control circuitry. The sensor operates from 12 to 24 VDC and consumes up to 30 mA. Light-ON or Dark-ON operation can be selected according to the required output logic, while response time is specified at 1 ms maximum. A 5 m pre-wired cable provides extended fixed wiring between the sensor position and associated control equipment. The square body uses PBT for the case, while denatured polyarylate is listed for the optical material.
For an Omron retro-reflective photoelectric sensor requiring NPN output and extended pre-wired connection, the relevant model is the E3Z-R61. Its 100 mm to 4 m sensing distance provides a broader stated range than the supplied 2 m cable listing. The M.S.R. function forms part of the retro-reflective optical arrangement, while selectable Light-ON and Dark-ON switching allows integration with different machine-control sequences. The 12 to 24 VDC supply range and 30 mA maximum current consumption support connection with compatible control systems. Its specifications also suit requirements for an Omron 4 m retro-reflective sensor and Omron NPN photoelectric sensor. For a related version with a 2 m pre-wired cable, see E3Z-R61 2M.
