Industrial Safety Photocell Reflective Human Body Protection Light Curtain Sensor

1. Self-inspection: Implement self-inspection within 2 seconds of power-on to ensure that there is no malfunction;

2. Using CPU self-check technology, with self-check function, when the ir light curtain has a problem, ensure that no wrong signal is sent to the controlled equipment (equivalent to disconnected state); it can be directly connected to the PLC for control, also Can add independent intermediate relay to control;

3. Using optical communication and professional optical system design, it has good anti-interference ability against external light such as welding arc light and flashing light;

4. There are 3 signal output methods: NPN, PNP, and relay (two groups can be output at the same time);

1. More responsive

　　The reaction time of all safety light curtains is within 10ms;

2. Dead zone filtering function

　　 When the object slowly passes the light curtain, the light curtain always outputs a stable disconnect signal, so as not to cause the machine to start by mistake, making the production safer and more reliable;

3. Circuit self-test

　　 Within 2 seconds of turning on the power, self-test is implemented to ensure that there is no fault. In addition, during normal work, it also conducts real-time self-test;

4. Power-on delay function

　　 3 seconds after power-on, the light curtain safety device can make the equipment work normally, which can give the operator and equipment a buffer time and improve the safety of the equipment and personnel.
