Industrial Applications

1. Hand Protection for CNC Machine Tool Loading

This light curtain can be installed at the loading/unloading point of a CNC machining center or stamping press. Its 480mm protective height and hand protection capability (25mm detectable object) ensure that an operator's hand or arm is detected immediately upon entering the hazardous zone, stopping the machine and preventing injury during material handling. Its ultra-slim profile (13.2mm) allows for installation in tight spaces common around machine tools without impeding workflow.

Problem Solved

Prevents operator injury (hand/arm) during manual loading or unloading of parts in high-speed or dangerous machinery operations, meeting PLc SIL1 safety requirements.

2. Restricted Access Protection on Automated Packaging Lines

Employed at access points to automated packaging lines, such as conveyor feed-in areas or palletizing stations, the SF2C-H24-P ensures personnel safety. The 0.1 to 3-meter operating range and IP67 rating make it suitable for environments where occasional splashes or dust are present, common in food or beverage packaging. The 480mm protective height covers typical hand access points, and the Type 2 PLc SIL1 certification provides adequate safety for less complex or slower-moving packaging machinery.

Problem Solved

Safeguards personnel from entanglement or crushing hazards on automated packaging lines, especially in damp or dusty conditions, ensuring operation within safety standards.

3. Small Robot Cell Entrance Safety

For smaller robotic cells performing assembly or pick-and-place tasks with less kinetic energy (e.g., collaborative robots in non-collaborative mode or light-duty industrial robots), this safety light curtain can monitor the entrance. The 20mm beam pitch for hand detection is crucial for human interaction areas. Its robust -10 to +55 °C operating temperature allows deployment in various factory environments. The ultra-slim design is beneficial when space is at a premium around a compact robot workstation.

Problem Solved

Provides reliable, space-efficient entry monitoring for small to medium robot cells, detecting human presence and preventing accidental interaction with moving robot parts, adhering to PLc SIL1 safety.
