Light curtain controller

The controller is the part of the photoelectric protection device that outputs control signals. It is connected to sensors (emitters, receivers) through signal cables, and to the control or warning circuits of mechanical equipment through control cables; Its main functions include three aspects: firstly, providing working power for sensors (emitters, receivers); The second is to process the light passing and blocking status signals generated by sensors (emitters, receivers) to generate a control signal; The third is to use control signals to control the control circuit or warning circuit of mechanical equipment. W-type: External single sided controller, capable of connecting 1 sensor or 1 set of light emitting and receiving devices; The structure is beautiful and sturdy, and can be directly installed on the machine bed wall or outside the electrical cabinet of other equipment. The connection between the W-type controller and the corresponding photoelectric protection devices (SNA, SNB, SNC, SNQ, STD, SQL series) and control units. N/ND type: built-in single sided controller, capable of connecting 1 sensor or 1 set of light emitting and receiving devices; The structure is compact and compact, and can be installed in the electrical cabinet of machine tools or other equipment. Connection between N/ND type controller and reflective photoelectric protection device (STF series) and control unit. S-type: External double-sided controller, capable of connecting 2 sensors or 2 sets of light emitters and receivers; The structure is beautiful and sturdy, and can be directly installed on the machine bed wall or outside the electrical cabinet of other equipment.
