Banner Engineering SM2A312DBZQD Proximity Sensor

The Banner Engineering SM2A312DBZQD Mini-Beam diffuse-mode proximity sensor is a compact AC-powered photoelectric sensor in Banner's Mini-Beam family, designed for diffuse sensing of reflective targets. This model is listed as part 27429 (SM2A312DBZQD) by Banner, confirming its diffuse-mode configuration and AC voltage operation. It accepts 24–240 VAC input and provides a SPST solid-state, 2-wire output with an integrated Micro 3-pin QD connector for quick disconnect. In diffuse mode, the sensor detects objects based on reflected light from the target, enabling reliable presence sensing without a separate reflector. With up to 300 mm sensing range, depending on target and alignment, the SM2A312DBZQD combines a small footprint with Banner's industrial reliability, suited for applications such as detecting parts on conveyors, feed lines, or packaging operations where space is at a premium and a simple ON/OFF signal is sufficient.
