Safety light grid (the light from the transmitter goes directly to the receiver to form a protective light curtain). When the light curtain is blocked, the receiver generates a light blocking signal and transmits it to the controller through the signal cable. The controller processes this signal to generate a control output signal, which controls the brake control circuit of the machine tool or the alarm device of other equipment to stop the machine tool. or security alarm.

Emitter: It is composed of several emitting devices, which emit infrared light;

Receiver: It is composed of several receiving devices to receive infrared light and form a protective light curtain in one-to-one correspondence with the emitting devices of the transmitter to generate light-passing and light-shielding signals, and at the same time transmit the signals to the controller through the signal cable to control the external equipment;

Controller: The signal processing unit provides power for the transmitter and receiver, and receives the light-transmitting and shading signals transmitted by the receiver to generate output control signals to control the brake control circuit of the machine tool or an alarm device for other equipment. The installed controller has a built-in Q-type controller. Type controller - P type external controller Two types of built-in controller The structure is small and compact - It can be installed in the control box of the equipment. Observation of shading state

Signal cable: used to transmit the signal between the controller and the transmitter and receiver;

Control cable: used to connect the controller with the machine tool and equipment to realize the safety control of the machine tool or other equipment;

Mounting bracket: fix the transmitter and receiver on the machine
