Banner Engineering SM31RDLBQD Photoelectric Sensor

The Banner Engineering SM31RDLBQD is a Mini-Beam DC Voltage Series receiver for opposed‑mode photoelectric sensing, designed to pair with Banner emitters in compact industrial automation applications. It operates from 10–30 V DC, uses an infrared LED sensing beam, and comes in a rectangular thermoplastic housing with an M18 mount and a 4‑pin M12 quick‑disconnect (QD) connector, all rated IP67 for protection in harsh environments. This receiver (SM31RDLBQD) features a black housing variant with a domed front and is intended for presence/absence or part detection on manufacturing lines, conveyors, and packaging equipment when used with a compatible Mini‑Beam emitter, delivering reliable, small‑footprint sensing in tight spaces.
