Technical Overview
The Omron E3Z-LT61 2M is a compact laser photoelectric sensor using laser through-beam (emitter and receiver set). Its manufacturer-rated sensing performance is 60 m; this exact variant has NPN open collector and a 2 m pre-wired cable. It uses a 655 nm Class 1 red laser, operates from 12–24 V DC ±10%, and is rated IP67 for industrial installations. Supply status is recorded as Unknown because current supply was not established.
Laser through-beam (emitter and receiver set); 60 m; NPN output, 2 m pre-wired cable, 12–24 V DC, IP67.
