Industrial Applications

1. Secondary Battery Manufacturing Assembly Line

Providing safety guarding in automated secondary battery production lines where space is highly restricted and metal contamination must be avoided. The resin body and stainless steel brackets meet strict material limitations.

Problem Solved

Eliminates the risk of copper/zinc contamination from conventional aluminum housings while maintaining a compact footprint.

2. Compact Material Handling and Packaging Machines

Guarding access points on compact packaging machinery where operators frequently reload materials. The 13 mm slim profile allows the light curtain to be mounted close to the hazard point, maximizing the machine's usable opening.

Problem Solved

Saves up to 12% usable workspace compared to conventional 43mm wide safety light curtains, increasing operator efficiency.

3. Food Processing and Cleanroom Conveyors

Ensuring operator safety at conveyor entry/exit points in food packaging and processing areas. The IP67 laser-welded polycarbonate housing withstands washdown procedures and avoids corrosion.

Problem Solved

Prevents ingress of water during washdowns without requiring bulky protective enclosures, preserving the compact machine layout.
