Banner Engineering SME312DQDP-75806 Photoelectric Sensor

The Banner Engineering SME312DQDP-75806 is a Mini-Beam Series diffuse photoelectric sensor in a compact 18 mm thermoplastic housing designed for M18 mounting, delivering reliable detection of targets up to 380 mm away with an infrared LED beam. It operates on 10–30 V DC and provides discrete outputs via a 5-pin connection, using a DB9 quick-disconnect pigtail that measures 20 ft (6 m) in length. The sensing mode is diffuse, and the unit supports light-on and dark-on operation with bipolar (NPN & PNP) outputs for flexible wiring. Key on-board features include a Teach button for remote teaching and a 1,000 ms power-up delay, making it straightforward to calibrate in busy lines. Built to withstand industrial environments, it is IP67 protected and rated for NEMA 4X compatibility, with an operating temperature range from −20 °C to 70 °C and humidity up to 90% at 50 °C. The sensor is encapsulated and uses an acrylic lens to focus the infrared beam, with a compact form factor that supports quick installation in tight spaces. Applications typically include presence or part detection on conveyors, packaging, and automated manufacturing lines where precise, near-field sensing is required and wiring flexibility is important due to the included DB9 QD cable.
