How To Choose A Safety Light Curtain
- Jul 09, 2018 -

First, you need to determine the protection height of the light curtain.

To determine the protection height of the safety light curtain, we must first distinguish the height of the light curtain and the protection height of the light curtain. Sometimes the customer is not aware of this problem, so it must be explained when selecting the model. The height of the safety light curtain is the overall height of the light curtain, and the protection height is the distance of all the beams of the light curtain.


Second, you need to confirm the required optical axis spacing is how big

The optical axis spacing is generally 10mm, 20mm, 30mm, 40mm, 80mm. The 10mm optical axis spacing is mainly used to protect the fingers, 20mm-30mm is mainly used to protect the palm, 40mm spacing is mainly used to protect the arm, 80mm spacing is mainly used To protect the human body. Customers can determine where they need protection based on their own use.


Third, you need to determine the distance of the light curtain

The shooting distance is generally 0-3m, and the farthest reach is 24m. This requires the customer to determine the width of the table according to the size of the machine.


Fourth, you need to determine what the output signal is.


The default output signals are NPN/PNP models, dual NPN signal types, dual PNP signal types, digital signals and relay models.


Under normal circumstances, according to these four items, you can basically select the type, but there are still many problems to be aware of, and specific analysis should be made on specific issues.
