Industrial Applications

1. Machine Guarding for Industrial Presses

The ST4-C11, when integrated with ST4 series safety beams, serves as a critical safety light curtain system for industrial presses and hazardous machinery.

Problem Solved

Ensures operator safety by rapidly halting machine operation (response time ≤25ms) upon intrusion into the protected area, preventing severe injuries. Its Category 4 / SIL3 compliance meets stringent safety requirements for high-risk equipment.

3. Perimeter Protection for Automated Material Handling Systems

The ST4-C11 and its associated ST4 safety beams can establish a virtual safety perimeter around automated guided vehicle (AGV) paths or conveyor systems in warehouses.

Problem Solved

Safeguards personnel and equipment by detecting obstructions or human presence, initiating a controlled stop of AGVs or conveyors to prevent collisions and accidents in dynamic material handling environments. The ability to serially connect multiple sensors is ideal for extensive perimeters.
