Industrial Applications

1. Automated Assembly Line Hand Protection

Installed at the point of operation on an automated assembly machine to protect operators from moving parts, robotic arms, or presses.

Problem Solved

Provides a high level of safety (PLe/SIL3) without physical barriers, allowing for frequent and easy access for part loading/unloading while ensuring the machine stops instantly if an operator's hand enters the protected zone. The 560mm height is ideal for protecting torso-level access points.

2. Packaging Machine Access Guarding

Used to create a protective field across the infeed or outfeed openings of a high-speed packaging machine, such as a cartoner or case packer.

Problem Solved

The fast 7ms OFF response time ensures the machine's hazardous motion is stopped before an operator can reach the danger zone. Its IP65 rating allows it to withstand dust and minor splashes common in packaging environments.

3. Semiconductor Fabrication Equipment Safety

Integrated into semiconductor wafer handling equipment to protect technicians during maintenance or loading procedures.

Problem Solved

The ultra-slim housing allows for installation in space-constrained, complex machinery. The 20mm beam pitch for hand detection prevents access to sensitive or dangerous components inside the equipment, meeting the high safety standards required in the electronics manufacturing industry.
