Industrial Applications

1. Industrial Machine Guarding for Manual Loading Stations

The SF4C-H28-J05 is ideal for safeguarding manual loading and unloading stations on industrial machinery, where operators interact directly with the machine's work area.

Problem Solved

Provides a reliable safety barrier, automatically halting machine operation if a worker's hand (due to 20mm beam pitch and 560mm protective height) enters the hazardous zone, preventing injuries during loading/unloading tasks. The IP67 rating ensures durability in environments with coolants or debris.

2. Assembly Line Robotics Safety Zone

This light curtain can establish a critical safety perimeter around high-speed robotic work cells on assembly lines, protecting personnel from potential crush or impact hazards.

Problem Solved

By creating a Type 4 safety zone with a 0.1 to 3m operating range, the SF4C-H28-J05 ensures that robots immediately cease operation if a human enters the defined area. Its ultra-slim design allows for integration into compact spaces within busy assembly lines.

3. Automated Material Handling System Entry/Exit Points

The SF4C-H28-J05 is well-suited for deployment at entry and exit points of automated conveyor or material handling systems where intermittent human access is required.

Problem Solved

It detects human presence (with hand protection capability) at pinch points or access areas, instantly stopping the material flow and preventing injuries during manual intervention or maintenance. The IP65 rating protects against dust and splashes common in such environments.
