Banner Engineering SM2A312W Mini-Beam Photoelectric Sensor

The Banner Engineering SM2A312W Mini-Beam is a self-contained photoelectric sensor in Banner’s Mini-Beam AC Voltage Series. It operates from 24 to 240 VAC and provides a solid-state SPST output via a 2‑wire connection, enabling straightforward wiring in compact automation layouts. In Divergent Diffuse mode, the sensor detects targets at up to 130 mm (about 5 inches) with a beam pattern designed to widen the sensing area as distance increases. It ships with a 2 m (6.5 ft) cable for easy mounting and wiring, making it a compact, plug‑and‑play solution for basic presence or object-detection tasks in space‑constrained environments. The SM2A312W is one of Banner’s AC‑powered Mini‑Beam sensors, balancing a broad input range with a simple two‑wire output to integrate with standard control circuits.
