Print mark contrast sensor
Description
Print mark contrast sensor, 25 mm detection range, RGB light, light/dark on, external Teach-in, push-pull output, M12 plug, Diffuse mode sensor for recording any print mark, Static TEACH-IN: automatic switching threshold adaptation, Optical system exchangeable by 90°, 30 µs response time, suitable for extremely rapid scanning processes, 3 emitter colors: green, red and bluefa. The contrast sensor series DK10, DK2X, DKE2X and DK3X have an extreme robust and IP67 tight industrial standard housing with eight M5 metal reinforced inserts for sensor mounting. The lenses are made of high grade glass. All sensors offer different light spot shapes and orientations and have powerful push-pull outputs (NPN/PNP/push-pull). The DK10 sensor series offers laser and LED light sources, a manual sensitivity adjustment and high sensing ranges up to 800 mm. The DK20/DK21/DKE2X standard contrast sensor series offers a very good contrast recognition and are available in extreme robust stainless-steel housings (DKE). The DK31/DK34/DK35 sensor series is designed for cutting edge contrast recognition at highest sensitivity level. The series DK20/DK34 offer a static Teach-In, the DK21/DKE21/DK31/DK35 series offer a dynamic Teach-In.
