SM2A31RLQDP is Banner Engineering’s Mini-Beam AC Voltage Series receiver, a self-contained photoelectric sensor that operates on 24–240 VAC and provides a solid-state AC switch output. In opposed-mode with an infrared sensing beam, it detects objects up to 30,000 mm (30 m) away and uses a 3-wire configuration with a 150 mm M12 pigtail quick-disconnect. The unit is housed in a thermoplastic rectangular enclosure designed for M18 mounting and carries IP67 and NEMA 4X protection, making it suitable for harsh industrial environments.
