PRINCIPLE OF PHOTOELETRIC SWITCH

The princinple of photoeletric switch: the projector will judge and react on the basis of light beam from the projector which is interdicted by object or emitted party.

DESCRIPTION OF TYPE

diffuse type:diffuse reflection  type  photoelectric switch integrates the transmitter and receiver.light reflected by the photoelectric switch is reflected back to the receiver by the detected object.

CAUTIONS

The  detection distance shown in the specification manual is in accordance with standard detected object.Actual detection distance will change  fo the size,color,surface evenness of detected object.Please ensure the stipulated room when set distance.

According to the change of detected object size and variation regulation of detection distance,bigger detected object,bigger feflection volume,longer detection distance,But when the size of optic receiving surface is bigger than the size of the detected object, the detection distance won't increase even if the object size increases again.
