Laser beams are harmful to the human eye. One should never look directly or through optical instruments into the laser beam. The diffuse sensors of the QS30 series from Turck Banner are easy-to-use high-performance laser sensors. This sensor is suitable for demanding applications thanks to its configuration options. The compact housing of the laser sensor features a large, easy-to-read bar graph display and bright LEDs for simple programming and status monitoring during operation. It offers learning mode programming, side mounting with integrated mounting holes, or front mounting. Excellent optical properties throughout the detection range, even at close range. Visible laser beam for diffuse detection.
