Safety light curtains are also photoelectric safety protection devices (safety protectors, punch protectors, infrared safety protection devices, etc.). In modern factories, people and machines work together, and they can be installed on some potentially dangerous mechanical equipment to protect workers. Prevent security incidents from happening. For Example, stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission, and handling equipment, and hazardous areas (toxic, high pressure, high temperature, etc.), are likely to cause personal injury to operators, can be installed.
1. The unique structural design ensures that there is no blind spot in the entire protection area;
2. Dual-channel OSSD output function, which can be cross-monitored with each other;
3. The self-diagnosis function can detect the failure circuit module of the light curtain. and issue an alarm signal;
4. With interlock reset, external test, and EDM function, strengthen the output monitoring ability;
5. Adopt optical communication synchronization, simplify the electrical connection and make the operation easier;
6. Meet the requirements of Type 4, SIL3 and PLe safety levels, and can be used for the protection of various parts of the body;
7. Waterproof design to meet outdoor applications
