The photoelectric protector is also named safety light curtain, safety grating and so on. By launching infrared, the photoelectric protector form infrared light curtain, and send out signal of intercepting when it is intercepted, to stop the potentially dangerous equipment of send out warning signal, in order to reduce the chance of injuring to operators in the work environment, and effectively protect the operators’ personal safety.
Ensure that the photoelectric protector don’t send the mistaken signal to the electro circuit which it controlled when it has faults
For the electromagnetism signal, the strobe lamp light, the arc of welding and surrounding light sources, it has better immunity.
The service life of relay is long ( more than 10 million times) , and the relay can be changed after be exhausted
The welding of components adopt to SMC technology, and have various anti-vibration measures.
Response time <=2ms,enabled the system the greatest degree to avoid danger.
