What Is the Difference Between Type 2 Safety Light Curtains and Type 4 Safety Light Curtains?
What Is a Safety Light Curtain?
Safety light curtain, also called safety grating, is a photoelectric safety protection device. It also has many names, such as safety protector, punch protector, infrared protection device, etc. It is a newly developed high-quality automatic control product that uses infrared scanning detection technology.
In modern factories, people and machines work together on some potentially dangerous mechanical equipment, such as stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission and handling equipment, and dangerous areas (toxic, high pressure, high temperature, etc.), which are easily used in environments that cause personal safety of operators. The role of the safety light curtain is to stop the machine quickly when the operator enters the dangerous area due to operating errors, thereby achieving the purpose of protecting the normal operation of people and machines.
Features of Type 2 Safety Light Curtain:
1. Low cost;
2. Performance: single CPU processor;
3. Dual safety channel output;
4. Self-diagnosis or external cycle test can be used for fault inspection;
5. Troubleshooting method to ensure safety performance;
6. Application scope: occasions and machines with medium or small damage, automated production equipment, material picking and placing devices, etc.
Features of Type 4 Safety Light Curtain:
1. Higher cost;
2. Performance: dual CPU processor;
3. Dual safety channel output;
4. More reliable control, slightly less affected by interference light;
5. Self-diagnosis for fault inspection, higher level redundant fault mutual inspection, etc.;
6. Application scope: high-risk occasions or machines with severe damage, which plays a good role in protecting dangerous areas.
