WL-OSEN

The Würth Elektronik optical sensors are used to sense light or sense objects with light. The reflective type optical sensor can be used to detect objects at short distances and can therefore be used in different white goods as optical switch, rotary encoder, interlock for touch or gesture detection within a detection range of a few mm.

Detection Principle

The reflective type optical sensor contains an IR emitter sending out IR light at 940 nm and collecting the reflected light in the phototransistor. If an object is close the optical sensor, the collector current of the phototransistor increases which can be used to detect if an object is in the vicinity.
