Pepperl+Fuchs’s DK12-11-IO Series Contrast Sensors are designed to reliably detect differences in two colours of media, with a three-colour light source. The sensors are IO-Link compatible and include Pepperl+Fuchs’ 4-in-1 output designed to reduce costs and stock requirements by delivering four output options from a single sensor. DK12-11-IO with IO-Link offers customizable and visible diagnostic LEDs, the ability to invert the output state and disable the adjustment potentiometer for tamperproof requirements, and logging the output. DK12-11-IO contrast sensors with RGB (red/green/blue) LEDs are especially designed to detect contrasts of yellow colours. These UL and cUL listed contrast sensors have a rugged, metal-framed housing with a connector that swivels for easy mounting in space-restrictive applications. They offer static and dynamic teach modes, in addition to manual and remote teach methods, in a single housing
