Description
These sensors have scratch-resistant optics and the emitted light can be switched off. They use the transit time measurement principle to measure the distance between the sensor and the object. For this reason, the object’s color, shape and surface characteristics have practically no influence on measurement results. Even dark objects can be reliably recognized. This product has been discontinued, but is still available as a spare part. Successor
