Industrial Applications

1. Hand Protection in Compact Robotic Assembly Cells

The Panasonic SF2C-H20-P safety light curtain is ideally suited for integration into compact robotic work cells where human operators require safe access for tasks like small part assembly or quality inspection. Its ultra-slim (13.2mm deep) design allows for minimal encroachment on valuable workspace, while the 400mm protective height and 20mm beam pitch ensure comprehensive hand detection.

Problem Solved

This solution prevents accidental injury to operators by rapidly stopping robotic movement when a hand or arm breaches the safety zone, even in confined spaces, ensuring compliance with Type 2 PLc safety standards due to its 20ms response time.

2. Personnel Safety in Food & Beverage Packaging with Washdown

This light curtain is an excellent choice for safeguarding personnel operating packaging machinery within the food and beverage industry, particularly at loading or unloading points that necessitate frequent washdowns. The robust IP67 rating ensures superior resistance to water jets and dust, while its 24V DC operation makes it seamlessly compatible with prevalent industrial control systems.

Problem Solved

It effectively protects workers from hazardous moving parts during operation and maintenance in wet or dusty environments, significantly minimizing downtime attributed to environmental damage to the safety equipment.

3. Point-of-Operation Guarding for Small Press Brakes and Material Feeders

The SF2C-H20-P can be effectively deployed for point-of-operation guarding on small press brakes, stamping machines, or material feeding systems where controlling hand access to hazardous areas is critical. Its rapid 20ms response time facilitates the calculation of a smaller safety distance, thereby maximizing productivity, and the ø25mm minimum detectable object ensures even finger detection.

Problem Solved

This system guarantees operator safety by preventing access to hazardous moving parts (e.g., cutting or pressing areas) during machine cycles, initiating a rapid machine shutdown upon any intrusion, all while maintaining a compact machine footprint.
