The machine can be protected by gratings with different safety levels. Large machines such as punches and shears can be protected by safety gratings with a safety level of four. The four-level protection type safety gratings can be protected from shock In terms of anti-interference, dust-proof and waterproof performance, it has higher performance than the secondary safety grating, and its durability is also stronger. Compared with the safety light curtain with secondary protection, the safety factor is not so high. So what kind of equipment is suitable for installing secondary safety light curtain?

The safety level of the safety grating affects the use of the equipment, so before the equipment chooses the safety grating, the safety level of the safety grating must be determined. The second-level safety grating is more suitable for dust-free assembly line workshops, small vibration-free equipment or areas. For safety protection, compared with the safety gratings of safety level four, most of the second class gratings are economical, and of course the stability is not as good as the fourth class.
