Banner Engineering SM312CV2QD Photoelectric Sensor

The Banner Engineering SM312CV2QD is a Mini-Beam DC Voltage Series self-contained photoelectric sensor with convergent optics, designed for fixed-focus detection of small parts in tight spaces and identified by part number 26903. In convergent mode, it focuses its beam at 16 mm and uses a blue 475 nm emitter to discriminate small targets, with a supply range of 10-30 V DC and selectable output behavior. The device provides two transistor outputs—one NPN and one PNP—suitable for wiring into PLC inputs, with the ability to switch between dark-on and light-on logic depending on the application, and it features a 4-pin M12 integral quick-disconnect (QD). Encased in an IP67-rated housing (NEMA 4X compatible), the sensor is built for harsh industrial environments, and as part of Banner's Mini-Beam DC Voltage Series, it offers a compact, rugged sensing solution for high-precision, near-field detection of small parts. The four-pin M12 QD connector supports quick installation and replacement, reducing downtime on lines where precise detection is required.
