KT5-2 contrast sensors are ideal for high-precision contrast detection, such as detecting marks on high-gloss materials. Thanks to the 3-color LED, the sensors are able to activate the best-possible emitted light source for each contrast. The device also offers various possibilities for adapting the switching point to the application via teach-in process or potentiometer. The sensor defines all necessary parameters automatically. The sensor then determines the ideal switching threshold from the two gray values detected. High-precision contrast detection, automatic gloss adaptation for highly reflective objects, a sensing distance of 10 mm, 20 mm and 40 mm, switching frequency of 10 kHz and individual alignment and mounting options make the device suitable for a wide range of tasks. Simple mounting is also ensured – the M12 plug connection can be rotated 90°.
