Banner Engineering SM91RSR Photoelectric Sensor

The Banner Engineering SM91RSR VALU-BEAM Receiver is a compact opposed-mode photoelectric sensor designed to detect small objects at a 3 m sensing distance when paired with a VALU-BEAM emitter, powered from 10 to 30 V DC with a 2 m (6.5 ft) cable included. Cataloged as 25288, this receiver provides bipolar outputs—one NPN and one PNP—for flexible control wiring and straightforward integration with PLCs and other automation hardware. As a member of the VALU-BEAM ESR/RSR family, the SM91RSR features a wide beam angle to ease alignment within the 3 m range, enabling quicker setup on conveyors and other space-constrained installations. This receiver is designed to work with Banner’s emitter for a complete sensing pair in industrial environments, offering reliable detection on moving production lines.
