Fork sensors in a miniature design are photoelectronic sensors. The emitter and the receiver are positioned opposite each other in a housing as a barrier. As soon as the light beam is interrupted, the sensor’s output switches. The use of visible red light and the beam marking on the fork legs make it easier to align the fork sensor. This fork sensor can be used to detect small holes, grooves, and notches as well as to detect small parts. The minimal construction volume, the flexible connection cable, and the integrated mounting holes enable use in confined installation situations, such as shuttles, AGVs, or robot grippers.
