The sensors are intended for non-contact measuring and monitoring the position of the edge (edges) of various objects, such as tapes, plates, substrates, etc.

The sensor operation is based on the so-called ‘shadow’ principle. The sensor consists of controller and measuring head which consists of two modules — transmitter and receiver.
Transmitter module consists of LED 1 and lens 2. Receiver module includes a photo-detector array 3.
Radiation of the LED 1 is collimated by the lens 2 and directed to the photo-detector array 3. With an object placed in the collimated beam region, shadow image formed is scanned with the photo-detector array 3. Controller calculates the position of the edge of the object.
