Banner Engineering Corporation SM312CQD Sensor

Banner Engineering's SM312CQD is a MINI-BEAM Series industrial standard photoelectric sensor in a compact rectangular thermoplastic housing with M18 mounting. It uses an infrared 880 nm convergent beam with a 16 mm focal point for close-range part detection, and it operates on 10-30 V DC with two discrete outputs: one NPN and one PNP (bipolar) delivered through a 4-pin M12 integral quick-disconnect. This sensor supports light/dark operate and a convergent sensing mode, and is encapsulated for rugged use. The IP67-rated enclosure and NEMA 4X compatibility protect it against dust and water in harsh environments; the operating temperature range is -20 to 70 C. Key electrical specs include a 1 ms response time, 100 ms power-up delay, and 300 µs repeatability, while the lens is acrylic and adjustments are via a potentiometer. The SM312CQD accepts 10-30 V DC supply, has 4 pins, and features LED indicators to show sensing status; it is designed for proximity sensing of small parts or objects in automation and conveyor-type applications, with a compact 18 mm barrel diameter and quick-disconnect convenience for fast field setup. This model is part of Banner's Mini-Beam lineup, known for reliable detection in compact form factors and easy integration into standard industrial fixtures.
