Safety light curtains are divided into optical synchronization and line synchronization. Optical synchronization means that the receiving and transmitting of the light curtain does not require any communication line connection. The transmission emits infrared light according to a prescribed rule, and the receiver receives it. After the light signal, compare the signal emitted by the transmitter, if they are consistent, it means that the light curtain is not blocked at this time, and the light signal is output. I don’t know if I can understand it.

When we connect the safety light curtain, the conventional safety light curtain generally has two data lines. One of the two data lines is a synchronization line, which mainly realizes the signal synchronization between the light emitter and the light receiver. When we block the signal light, the light emitter and the light receiver receive the signal at the same time to achieve signal synchronization

When we need to purchase a safety light curtain, we don’t know how to choose. There are tens of millions of specifications and models of the light curtain. How do we choose? Many people are not very clear. They only know that a safety light curtain is needed. Let me briefly talk about the precautions for selection.

When we choose a light curtain, we need to understand the following points:
1. The length of the light curtain
2. The beam distance of the light curtain
3. The optical axis spacing of the light curtain (refers to the distance between light and light)
4. The output signal of the light curtain (output signal mode)
5. The size of our installation space, choose the size of the light curtain
6. Installation method

As long as we understand the above 6 points, we can give these 6 points to the manufacturer, and the manufacturer can select the corresponding model according to our requirements. This will improve our work efficiency!
