The red LED source and PNP output handle standard industrial object detection over short-to-medium spans. Sealed to IP67, it resists washdown environments; the 2 m cable simplifies field wiring without an M8 connector. Operating range is 12–24 V, switching 100 mA loads. The compact body measures 10.8 mm wide, 20 mm high, and 31 mm deep, fitting tight panel layouts or machine frames. ## Cable vs. Connector — Panel Drop-In Check The closest functional sibling is E3ZT86ADOMI: identical 10 m range, PNP output, red LED, and IP67. Two differences drive procurement: E3ZT86ADOMI uses an M8 4-pin connector (no cable), and its operating temperature extends to -40 °C vs. -25 °C for this part. If the panel was specced for the connector variant, the cable-fixed E3ZT81A2MOMI will not drop in without rewiring — the cable needs to be terminated at the sensor end or replaced. For new builds where conduit or cable gland is preferred, the cable variant saves one junction.","metaTitle":"Omron E3ZT81A2MOMI PNP Through Beam 10m Cable","metaDescription":"Omron E3ZT81A2MOMI through-beam photoelectric sensor, PNP output, 10 m sensing distance, 1 ms response, 2 m cable, IP67.
