Function: LTK2-8-HS-6000/31/105

Diffuse mode sensors LT(K)2 are used when people, objects, or vehicles are to be detected in a precisely defined area. The devices are extremely sturdy and resistant to mechanical strain. In background evaluation operating mode, the sensors can be used with any background. In background suppression operating mode, the background serves as a reference area. This enables highly reflective objects to be reliably detected as well. In addition, this operating mode offers an option for testing.
