Omron E3ZM-T83 2M Photoelectric Sensor
Omron E3ZM-T83 2M is a PNP through-beam photoelectric sensor intended for short-distance sensing across a specified 0.8 m span. The optical arrangement uses the E3ZM-T83-L emitter and E3ZM-T83-D receiver, with an infrared LED creating the beam between the two sensing units. The PNP output transfers the switching state to compatible industrial control inputs, while Light-ON and Dark-ON operation supports alternative machine sequences. Operating voltage is 10 to 30 VDC, and both the emitter and receiver consume up to 20 mA. The model includes 2 m pre-wired cables, while response time is stated at 1 ms maximum. Within the E3ZM Series, the E3ZM-T83 2M provides compact through-beam sensing within the 0.8 m PNP sensor range across Omron Sensor Products.

The Omron E3ZM-T83 2M Photoelectric Sensor provides through-beam sensing across a relatively short specified distance of 0.8 m. The optical system consists of the E3ZM-T83-L emitter and E3ZM-T83-D receiver, with an infrared LED establishing the beam between them. The PNP output transfers the switching state to compatible PLC and machine-control inputs whenever the optical path changes. Operating voltage is 10 to 30 VDC, and each sensing unit consumes up to 20 mA. Light-ON and Dark-ON operation supports different control sequences, while response time is specified at 1 ms maximum. The supplied 2 m pre-wired cables provide fixed electrical connection. SUS316L is listed for the body and methacrylate resin for the optical material, matching the stated square-type configuration.
Where an Omron through-beam sensor needs PNP switching but does not require a long optical span, the relevant model is the E3ZM-T83. Its 0.8 m sensing distance is much shorter than the 15 m T81 variants, providing a different optical arrangement for machinery with closer emitter-to-receiver spacing. The 2 m cables allow direct routing to associated control equipment, while the 10 to 30 VDC supply supports compatible industrial inputs. Each optical unit is limited to 20 mA maximum current consumption, and the 1 ms response defines the switching speed. For a related PNP through-beam model offering a much longer 15 m range, see E3ZM-T81 2M.
