In one part of the note feeding table of the counting machine, there is a transmitting and receiving infrared counter which is used as the reflector of whether there is a note or not. It is commonly known as the photoelectric switch ITR, which is used to detect whether there is a note put in. For the detection of this item, in the basic principle, we can use the separated infrared tube to complete this function. However, because of the mechanical system, we only place the detection components on one side, so we only choose the double beam tube. In one part of the cash counter, there is a pair of infrared tubes to distinguish whether there is a bill that has not been removed, Here we use a pair of infrared tubes to carry out the power switch resolution.

In the paper counting machine printing paper detection can be used billion light photoelectric switch, infrared tube and other material number!

Infrared transmitting tube: ir333c-a
