Product Description

Cat4 Safety Light Curtain Sensor with Ce The working principle of the light emitted by the transmitter to the receiver, the formation of protective light curtain. When the light curtain is blocked, the receiver generates a shading signal, transmitted through the signal cable to the controller, the controller will process the signal to produce a control output signal to control the machine's brake control circuit or other equipment alarm device, To achieve the machine to stop the operation or security alarm. The controller has both built-in and external.
