Second emitter LED for suppression of critical reflective backgrounds

Your benefits

Reliable detection of objects of all types
Low-cost integration in a machine as, unlike other types, the WTB4-3 can be integrated optimally in cramped installation conditions so it is closer to the process
The WTB4-3 enables smart machine design as reliable object detection is possible in the tightest space situations and with close-by critical backgrounds.
Reliable detection thanks to best-in-class background suppression and high resistance to extraneous light
Robust mounting due to M3 threaded metal sockets for a long service life.
