Omron E3ZM-LS61H 2M Photoelectric Sensor
Omron E3ZM-LS61H 2M is a background-suppression reflective photoelectric sensor specified for a short sensing span from 10 to 100 mm. Its red LED supplies the optical light, while the BGS principle helps establish the intended target zone with less influence from surfaces beyond that position. The NPN output communicates the switching state to compatible machine-control inputs, and Light-ON or Dark-ON operation provides a choice of output logic. The sensor operates from 10 to 30 VDC, consumes up to 25 mA, and includes a 2 m pre-wired cable. Response time is specified at 1 ms maximum. The E3ZM-LS61H 2M provides fixed wiring within the 100 mm BGS sensor range across Omron Automation Products.

The Omron E3ZM-LS61H 2M Photoelectric Sensor uses BGS reflective sensing across a specified 10 to 100 mm range. A red LED provides the optical source, while the background-suppression principle establishes a short target zone with less response to surfaces positioned farther behind it. The NPN output communicates the switching state to compatible PLC and machine-control inputs. The sensor operates from 10 to 30 VDC and consumes up to 25 mA. Light-ON and Dark-ON operation provides alternative output behavior, while response time is stated at 1 ms maximum. A 2 m pre-wired cable gives fixed electrical connection between the sensing point and control circuitry. SUS316L is listed for the body, with methacrylate resin specified for the optical material.
When the requirement calls for an Omron NPN background suppression sensor with a compact 100 mm maximum range, the relevant model is the E3ZM-LS61H. Its shorter optical span distinguishes it from the LS62H version, which is specified to 150 mm. The 2 m cable suits installations where the control connection is located relatively close to the sensor, while the 10 to 30 VDC supply range supports compatible industrial input circuitry. The BGS arrangement is useful when the intended sensing zone needs to remain in front of a background surface rather than relying only on the amount of returned light. For the same 10 to 100 mm NPN configuration with longer fixed wiring, see E3ZM-LS61H 5M.
