1.1 Way to Select

1.2.1、How to Chose The Pitch

Becaouse there is the dead from the beam,so detecting object must be 6mm larger than the pitch，just refer to below

1.1.1 How to chose detecting distance

20 – 35000 mm can be for through-beam distance， default is 1000 mm、2000 mm、3000 mm.

1.2.3、How to Calculate The Protection area

1.2.4、Signal Output Mode to Chose

 

4、brief of use

Horizontal installation is done,indicator from receiver keep solid bright ，indicator show green from emitter ，NPN NC signal output low level（PNP NC signal is high level）；
When an opaque object is blocked,indicator is red from receiver，NPN NC signal output high level（PNP NC signal output low level）；
Level width of fall detection of products depend on the interruption time that object pass through the beam when it falls down；usually main board of vending mahcine use external interrupt to detect the fall signal,output voltage in high level is as the input voltage,
