Banner Engineering SM312FP Photoelectric Sensor

Banner Engineering SM312FP Mini-Beam Photoelectric Sensor is a compact, self-contained DC-powered fiber‑optic sensor designed for plastic fiber applications. Running on 10–30 VDC and delivering up to 150 mA, it uses two outputs—one NPN and one PNP bipolar—across a 4‑wire interface for flexible wiring in tight spaces. The SM312FP variant employs plastic fiber optics and is offered with fixed cable or pigtail connections to simplify installation in conveyors, packaging lines, or automated assemblies. Equipped with a 650 nm red visible LED, this sensor is part of Banner’s Mini‑Beam family: a DC voltage series known for small form factor and reliable sensing performance. With the fiber optic configuration, it can detect small parts or through narrow gaps where traditional sensors struggle, and the four‑wire output arrangement supports logic wiring and independent sensing paths as needed. For installers, the SM312FP’s plastic fiber model designation indicates its fiber type and associated accessories, providing a versatile solution for compact detection tasks.
