Banner Engineering SMU315LP Photoelectric Sensor

The SMU315LP Mini‑Beam Universal Polarized Retroreflective photoelectric sensor from Banner Engineering detects small objects with precision across a 10 mm to 3 m sensing range and operates on 24–240 V AC/DC. Its SPDT electromechanical relay output provides reliable switching, and it ships with a 2 m (6.5 ft) cable for straightforward wiring. This polarized retroreflective model uses a visible red LED indicator at 650 nm and supports Light/Dark operate behavior. The rectangular thermoplastic housing, with an 18 mm barrel diameter and M18 mounting, houses a 5‑pin connection and includes a potentiometer for sensitivity adjustment. The unit is IP67 rated and compatible with NEMA 4X environments, suitable for demanding industrial settings. Ambient temperature range is −20 to 55 °C, and humidity tolerance reaches up to 90% @ 50 °C. The sensor’s maximum sensing distance is 3000 mm, and the lens is acrylic, contributing to durable performance in challenging light conditions. This device is part of Banner’s Mini‑Beam Universal Voltage Series, delivering polarized retroreflective detection where reliable reflection from the target is essential for accurate sensing in cluttered backgrounds.
