Industrial Applications

1. Robotic Work Cell Guarding

Utilizing the SF2C-H32-P light curtain at access points to robotic work cells in automated assembly lines. Its 640mm protective height effectively guards the entry for hands and arms.

Problem Solved

Prevents severe hand and arm injuries to human operators by immediately halting robotic arm movement when the 25mm minimum detectable object threshold is breached. The 24VDC PNP output integrates seamlessly with standard industrial control systems, meeting Type 2 safety requirements.

2. Automated Packaging Machine Access Protection

Implementing the SF2C-H32-P as a safety barrier around high-speed packaging and palletizing machinery, especially in areas with limited space due to its ultra-slim profile.

Problem Solved

Ensures operator safety by detecting intrusion into dangerous moving parts of packaging machines. The IP67 rating provides resilience against dust and moisture common in food and beverage packaging lines, while the ultra-slim 13.2mm width allows installation in confined spaces, enhancing productivity without compromising safety.

3. Conveyor System Pinch Point Safeguarding

Deploying the SF2C-H32-P along conveyor systems at pinch points, material transfer zones, or other areas where personnel might access moving parts.

Problem Solved

Minimizes the risk of crushing or entrapment injuries by rapidly detecting hands or objects entering the conveyor's operational zone, triggering an emergency stop. The optical synchronization feature simplifies installation and wiring across extended conveyor layouts, and the fast 20ms OFF response time ensures quick machine shutdown.
