The QS30LDLQ is a diffuse-mode Laser Sensor with 1 NPN and 1 PNP bipolar output. The WORLD-BEAM® QS30 series 02786 sensor is an easy-to-use, high-performance laser sensor whose many configuration options make it suitable for demanding applications. It provides high-performance sensing in low-contrast applications at relatively long range. It features static, dynamic and single-point TEACH-mode programming, in addition to manual fine adjustment, remote programming and security lockout options. A SETUP mode also may be used to change the sensor output response. The sensor compact housing has a large, easy-to-see bar graph display plus bright LEDs for easy programming and status monitoring during operation. The sensor can be side-mounted, using its integral mounting holes or front-mounted, via its 30mm threaded barrel.
