Omron E3ZM-LS81H 5M Photoelectric Sensor
Omron E3ZM-LS81H 5M is a PNP BGS reflective photoelectric sensor designed around a specified 10 to 100 mm sensing distance. Its red LED supplies optical light to the target area, while background suppression helps define the required switching zone with reduced response to surfaces beyond it. The PNP output communicates the sensing state to compatible PLC and machine-control circuitry, and Light-ON or Dark-ON operation supports different switching requirements. Operating power is 10 to 30 VDC, with current consumption specified at 25 mA maximum. A 5 m pre-wired cable offers longer fixed wiring than the 2 m version, while response time is 1 ms maximum. The E3ZM-LS81H 5M provides extended connection within the PNP short-range BGS sensor range across Omron Automation Sensors.

The Omron E3ZM-LS81H 5M Photoelectric Sensor uses PNP BGS reflective sensing across a stated range from 10 to 100 mm. Its red LED establishes the short optical sensing area, while background suppression helps reduce switching influence from surfaces beyond the selected target position. The PNP output carries the sensing state to compatible PLC and machine-control circuitry. The unit operates from 10 to 30 VDC and consumes up to 25 mA. Light-ON and Dark-ON operation supports different machine sequences, while the response time is specified at 1 ms maximum. A 5 m pre-wired cable provides extended electrical routing, making this configuration distinct from the shorter 2 m version. SUS316L is specified for the body and methacrylate resin for the optical material.
For an Omron PNP background suppression sensor that needs additional wiring length while retaining a 100 mm maximum sensing distance, the relevant model is the E3ZM-LS81H. The optical specification remains 10 to 100 mm, so the longer cable changes the installation reach rather than the sensing span. Its 10 to 30 VDC supply, 25 mA maximum current consumption, and 1 ms response are shared electrical characteristics within the supplied configuration. The BGS principle keeps the sensing requirement focused on the selected short-range target zone. For the same PNP model with a shorter 2 m pre-wired connection, see E3ZM-LS81H 2M.
