Product Description
This listing is for the EMITTER ONLY. The receiver is NOT included.
The Banner Engineering SMA31ELQD is a MINI-BEAM AC-voltage series opposed-mode photoelectric emitter designed for through-beam sensing applications up to 30 meters (100 ft). It operates on 24–240V AC (50/60 Hz) and features a rugged, epoxy-encapsulated thermoplastic housing rated IP67 and NEMA 4X. The unit connects via a 3-pin Micro (1/2 in.) integral quick-disconnect and is switch-selectable for light-operate or dark-operate modes, with an infrared LED sensing beam and LED status indicator.
