No reflector, no retro-target; just an emitter and receiver pair that need a clear line of sight. The laser is Class 1 under IEC/JIS, Class 2 under FDA, so no special enclosure requirements for most industrial installations. Runs on 12-24 VDC and sinks up to 100 mA via an open-collector output — typical NPN wiring, but the spec sheet doesn't call out polarity explicitly, so confirm your load side before panel-punching. Current consumption is 35 mA total (15 mA emitter, 20 mA receiver), which means a single 24 VDC supply can power both ends without a separate line drop. The spot diameter at 3 m is 5 mm, so alignment for the full 60 m range needs a laser sight or a careful two-person setup.","metaTitle":"Omron E3Z-LT81 Photoelectric Sensor, Through-beam 60 m","metaDescription":"Omron E3Z-LT81 through-beam photoelectric sensor with 60 m range, red laser 655 nm Class 1/Class 2, 12-24 VDC, open collector 100 mA.
