When our punching protection device is purchased, there are several problems. We must make it clear. Otherwise, the safe grating of the buying back may not be suitable for ourselves. Of course, the regular safety grating manufacturer will definitely be with You make it clear, because no one wants to encounter a return and exchange.

Machinery requires the height of the protected area, and it is very important to distinguish the "induction area" and "protected area height". The distance from the upper edge of the first beam to the lower edge of the bottom beam is the height of the induction area. The height of the protected area refers to the effective protection area. The size of the object is greater than the resolution of the safe grating, so that the beam can be darkened safely.

Infrared spacing (resolution): According to the part where the body needs, the light spot spacing (resolution) (R) of the safety grating refers to the minimum size that can make at least a light beam. The resolution is determined according to the geometric characteristics of the diameter and the center distance; it has nothing to do with the external and operating conditions of the safety grating.
