Banner Engineering SM312FP Fiber Optic Amplifier

The SM312FP is Banner Engineering’s Mini-Beam fiber optic amplifier with plastic fiber optics, engineered for tight spaces where a compact sensor interface is required. It runs on 10–30 V DC and, as a 4-wire device, drives two bipolar outputs (one NPN and one PNP) through a 2 m cable, simplifying wiring in compact automation cells. As a Plastic Fiber Optic model in the Mini-Beam family, the FP suffix indicates the fiber type, and Banner provides performance curves specifically for SM312FP plastic-fiber models, with range and response varying by chosen fiber and mode. Applications include presence/absence detection in packaging, conveyors, and other small-form sensing tasks where precise alignment is aided by Banner’s Alignment Indicating Device (AID).
