The Omron E3G-R17-G is a retro-reflective photoelectric sensor rated for 13 m sensing distance. Output is field-selectable between NPN and PNP, with light-on/dark-on toggled via the L-ON/D-ON switch. A red LED light source and M12 4-pin connector cover the usual 10–30 VDC supply. Plastic rectangular body, no IP rating listed — keep it indoors or in a dry cabinet.

Frequently asked questions
What is the sensing type and range?
Retro-reflective, maximum 13 m sensing distance.
What output types does it support?
NPN or PNP selectable, plus light-on/dark-on selection.
Can the E3ZM-T61 replace the E3G-R17-G directly?
No. The E3ZM-T61 is a through-beam sensor (separate transmitter/receiver) with a pre-wired cable, while the E3G-R17-G is retro-reflective with an M12 connector. Different wiring, different sensing setup.
