Safety light curtain, protecting the operator's personal safety!

1. Working principle:

The safety light curtain consists of five parts: a light emitter, a light receiver, a controller, a signal cable, and a control cable (supporting PNP/NPN output). 

The light emitted by the illuminator is directed towards the receiver, forming a protective light curtain. When the light curtain is obstructed, the light receiver generates a light blocking signal, which is transmitted to the controller through a signal cable. The controller processes this signal to generate a control signal, which controls the braking control circuit of the machine tool or other equipment alarm devices to achieve machine tool parking or safety alarm.
