Those who have purchased Light curtain and photoelectric protection devices know that when we purchase Light curtain, our manufacturers often involve some parameters, such as protection height, protection length, optical axis spacing, output mode, etc., and now we will talk about the meaning of these commonly used terms in detail, hoping that you can better understand the safety light curtain.

1. The protection height is a question that the Light curtain manufacturer will inevitably ask you, that is, how high the safety light curtain should be selected according to the height that needs to be protected in the specific reality. For general punching machines, the protection height is uncertain, and the importance of the punching machine can also determine the protection height.

2. Choose the appropriate model for the protection length, which is the length of the protection area! Generally, it is 0-10m. Basically, all Light curtain can be achieved. If they exceed the standard, they may be customized or consulted carefully.

3. The optical axis spacing is the distance between one light-emitting unit on the light receiver of the safety light curtain. Generally, the optical axis spacing of Light curtain is 10mm, 20mm and 40mm.

4. The general output methods for photoelectric protection devices include NPN output and PNP output.
