Banner Engineering SM312FP Photoelectric Sensor

The Banner Engineering SM312FP Photoelectric Sensor is a compact Mini-Beam DC voltage sensor with a built-in emitter and receiver in a single self-contained unit for plastic-fiber sensing. The SM312FP is a plastic-fiber model in Banner’s Mini-Beam family and is cataloged as 25916. It provides 1 NPN and 1 PNP bipolar output, enabling both sinking and sourcing interfaces with common automation controllers. The sensor uses a visible red LED emitter at 650 nm and is documented as a plastic-fiber model with performance curves specific to SM312FP plastic-fiber variants, including diffuse-mode characteristics. Ideal for small-part presence/absence detection in packaging and other automated lines where space is limited and fiber-based sensing offers flexible installation.
