Banner Engineering QS30LD Laser Proximity Sensor

The Banner QS30LD World-Beam Laser Diffuse-Mode Proximity Sensor is a long-range, Class 1 laser sensor designed for diffuse-reflective object detection up to 400 mm. It operates on 10–30 V DC and provides NPN or PNP outputs to simplify integration into standard industrial controls. As part of Banner’s QS30 Series, the QS30LD combines compact form with rugged construction for reliable sensing in demanding environments. The diffuse-mode operation means targets are detected by reflected light without requiring a separate reflector, making it well suited for presence or part-detection tasks on production lines where geometry or surface finish varies. For users needing longer cable runs, Banner offers 9 m (30 ft) cable models by adding the W/30 suffix to the model number (for example, QS30LDW/30), preserving the same sensing performance. The QS30LD family is designed to deliver consistent switching across a range of target colors and contrasts, with the familiar World-Beam interface and setup process that supports quick teaching and deployment.
