Banner Engineering 26060 SM2A31R Photoelectric Sensor

Banner Engineering's SM2A31R is a Mini-Beam receiver designed for opposed-mode photoelectric sensing. It operates on 24–240 V AC and provides a solid-state SPST two-wire output, with a 2 m (6.5 ft) cable included. The infrared sensing beam (880 nm) supports a 3 m detection range, making it well-suited for compact machine-vision and automation tasks where a small, rugged receiver is required. The housing carries IP67 protection and a NEMA 4X rating, enabling reliable use in damp, dusty, or washdown environments. Cataloged as part 26060, the SM2A31R belongs to Banner’s Mini-Beam AC Voltage Series and is intended to pair with a compatible Mini-Beam transmitter to form a complete sensing pair for object detection, part verification, or conveyor-line sensing in industrial settings.
