1. Working Principle
The emitter transmits light signal to the receiver and form an protection curtain. The receiver monitors the light transmission of the light curtain and process the through or off status of light signals. It outputs low level via NPN audion or high level via PNP audion. And then it will transmit the signal to machine tool PLC or alarm circuit, realizing the stop or alarm of machine tool.

Note:
1. N represents the output mode by default is NPN. The 0V output is valid. Other code can be adopted if in need by customers. For example, if PNP needed, change N into P.
2. Besides the above mentioned models, light curtains with special dimensions can be customized.
7. Selection of Brackets
8. Application
Well applicable to outdoor scenarios or machines, such as pipe bending machine, automation equipment and hydraulic press, etc.
