The safety light curtain infrared sensor is a kind of safety protection device. It emits infrared beams through the emitter, and the receiver receives the infrared beams to form an infrared light curtain protection wall. When one of the beams in the light curtain is blocked, the sensor will send a signal to make The running equipment is stopped or alarmed, which can effectively avoid the occurrence of safety accidents.

Safety light curtain sensors are mainly used in safety protection equipment in industrial production. They are commonly called safety light curtains, safety gratings, and photoelectric protection devices. Multiple parallel infrared rays form a protective wall like a movie screen. It will stop working to protect the personal safety of the operator. It is a new type of high-quality automatic control safety protection product, using infrared scanning detection technology. The transmitting device and the receiving device are installed on both sides, and the digital program is controlled by the single-chip microcomputer and the microprocessor inside, so that the infrared transceiver unit forms an infrared light curtain warning barrier in the high-speed scanning state. When people and objects enter the light curtain barrier area, The control system quickly converts and outputs high and low level signals to make the load act. When people and objects leave the light curtain warning area, the load is normally automatically shut down, so as to achieve the purpose of safety protection.
