Banner Engineering SM312CQD Photoelectric Sensor

The Banner Engineering SM312CQD Mini-Beam Photoelectric Sensor is a compact DC-voltage model in Banner’s Mini-Beam line, housed in an IP40-rated cylindrical package with a 4-pin M12 quick-disconnect (QD) connector for reliable wiring. It operates from 10–30 V DC and provides bipolar outputs (1 NPN and 1 PNP), enabling straightforward interfacing with standard controls, with a 4-pin M12 Integral QD connection. The sensor uses an infrared emitter at 880 nm in a convergent (focused) configuration with a 16 mm focal point, allowing precise detection of small parts in tight spaces. This SM312CQD model is designed for Mini-Beam DC Voltage applications and is compatible with Banner's broad ecosystem of sensors; it is commonly used for presence/absence detection of small components on automation and packaging lines where a compact, quick-connect sensor is advantageous, and the integrated M12 QD minimizes wiring time in tight installations.
