Reflection principle

With a light-band of up to 60 mm, the RK46C is essentially a small light curtain against a reflector, with a resolution selectable by teach level for detecting irregular objects or undefined leading edges.

The CSR 780 is a switching light curtain that functions according to the reflection principle and has a high resolution and fast response time specifically for counting objects on machines or for ejection monitoring. With the reflection principle, an operating range up to 700 mm and gapless detection of small objects, e.g., 10 x 10 x 1 mm at up to 3.5 m/s are possible. Furthermore, readjustment is performed in the event of soiling and a warning output is provided for prefailure messages.
