Omron E3ZM-LS61H 5M Photoelectric Sensor
Omron E3ZM-LS61H 5M is a BGS reflective photoelectric sensor intended for target sensing from 10 to 100 mm. A red LED establishes the optical sensing area, while background suppression helps restrict switching to the required target region instead of responding primarily to surfaces beyond it. Its NPN output connects with compatible PLC and machine-control circuitry, with Light-ON and Dark-ON operation available for different control logic. The sensor runs from 10 to 30 VDC and consumes up to 25 mA. A 5 m pre-wired cable provides additional routing distance from the sensing point to the control connection, while response time remains 1 ms maximum. The E3ZM-LS61H 5M extends fixed wiring within the short-distance BGS sensor range across Omron Industrial Products.

The Omron E3ZM-LS61H 5M Photoelectric Sensor provides BGS reflective sensing through a specified target span from 10 to 100 mm. Rather than relying only on reflected intensity, the background-suppression arrangement helps keep the switching point associated with the intended short-range target area. A red LED supplies the optical light, and the NPN output communicates the resulting state to compatible industrial control circuitry. The unit operates from 10 to 30 VDC, with current consumption limited to 25 mA maximum. Light-ON and Dark-ON operation supports different output sequences, while response time is specified at 1 ms maximum. Its 5 m pre-wired cable gives substantially more electrical routing length than the 2 m configuration. SUS316L and methacrylate resin are listed among the supplied materials.
For an Omron BGS photoelectric sensor requiring NPN switching and a longer pre-wired connection, the relevant model is the E3ZM-LS61H. The longer cable does not change the stated 10 to 100 mm sensing range; instead, it extends the distance available between the sensor and machine-side connection. This makes the 5 m listing electrically different from the shorter cable option while retaining the same optical specification. Its 10 to 30 VDC supply range, 25 mA maximum current consumption, and 1 ms response define the principal electrical characteristics provided in the source. For a related NPN BGS version with the same sensing span but shorter 2 m wiring, see E3ZM-LS61H 2M.
