The sensor, EPS-5051, is photoelectric illuminative sensor, it utilizes IR for projecting and receiving, and identifying the edge position where it is accurately. It could aim at different detected objects to do adjustment in the range of accuracy from -0.25mm to 10mm, the detected objects include different fabrics, plastics, non-transparent adhesive tape, conveyer…etc.
The sensor EPS-5051 is composed of 6pcs of IR projectors and 6pcs of IR receivers. Projector throws the light to receiver; detected object is on the middle, the position of cloth edge is decided by the amount of reception from receiver. The green led is the power indicator of sensor. The red led is the edge position indicator, it lights that means there has obstacle.
