Industrial Applications

1. Machine Guarding for Stamping and Press Machines

The SF4C-H8 safety light curtain provides essential hand protection when installed at access points of stamping or pressing machinery. Its 160mm protective height and ability to detect objects as small as ø25mm ensure that an operator's hand entering the danger zone immediately triggers a machine stop, preventing severe injuries.

Problem Solved

Prevents critical hand injuries to operators by ensuring immediate machine shutdown upon detection of a hand or arm breaching the hazardous area.

2. Robotic Cell Safety Perimeter

Implementing the SF4C-H8 within robotic work cells establishes a critical safety perimeter. Its robust IP67 rating ensures reliable operation in demanding industrial environments, while the 0.1 to 3m operating range offers flexibility in defining the safety zone, prompting robots to cease movement upon human intrusion.

Problem Solved

Safeguards personnel from accidental contact with active robotic systems by halting robot operation when an individual enters the designated safety area.

3. Automated Assembly Line Access Protection

The ultra-slim 13.2mm profile of the SF4C-H8 makes it ideal for integrating safety at loading/unloading stations or maintenance access points on automated assembly lines where space is severely restricted. Operating on a standard 24VDC, it provides essential protection without requiring extensive modifications to existing setups.

Problem Solved

Protects operators interacting with fast-moving components on assembly lines, particularly in confined spaces where traditional bulky safety devices are impractical.
