Ultrasonic web edge sensor bks+, IO-Link

Microsonics bks+ is a fork sensor used for scanning the edges of sound-impermeable materials like foil or paper. It is equipped with a broad working range for contact free web edge detection. Both transducer and receiver are placed in a single fork housing. The transducer in the lower leg emits short sound pulses. These are detected by the ultrasonic receiver in the upper leg of the fork. A material embedded in the fork covers the sound gap, and thereby dampens the receiving signal in depending on the coverage. In addition, the device features IO-link interface to meet the new industry standard.
