Q：What is a long-distance bi-directional projection screen? What are its advantages?
A：
DADISICK-QA series long-distance bi-directional safety light curtains are safety devices that utilize the principle of bi-directional projection. They are mainly used in applications that require coverage of larger areas, such as robotic automation production lines and automotive assembly lines. Compared to traditional safety light curtains, the DADISICK-QA series offers several advantages:
1. Wide Coverage: Long-distance bi-directional safety light curtains can cover larger areas, replacing multiple sets of traditional safety light curtains, reducing equipment costs and the difficulty of installation and maintenance.
2. Extended Range: Traditional safety light curtains typically have a range of a few meters, while long-distance bi-directional safety light curtains can reach tens of meters, meeting specific requirements.
3. Fast Response Time: Due to the bi-directional principle, long-distance bi-directional safety light curtains have a very fast response time, detecting objects in milliseconds and ensuring the safety of operators and equipment.
4. Strong Anti-Interference Capability: Long-distance bi-directional safety light curtains use digital signal transmission, effectively resisting the influence of electromagnetic interference and other sources of interference.
Indeed, long-distance bi-directional safety light curtains have various advantages, including wide coverage range, extended operating distance, fast response time, and strong anti-interference capability. These features make them widely applied in industries such as robotic automation production lines and automotive assembly lines, where large areas need to be covered for safety purposes.
