Product Introduction
Our SF2C Safety Light Curtain Type2 PLc SIL1 is an ultra-thin safety light curtain sensor for machine guarding. It features simple installation and reduced wiring workload. The whole series maintains a fixed 20ms response time, and its compact resin housing achieves IP67 protection grade. It has obtained global certifications including CE, TÜV, NRTL, OSHA/ANSI and JIS, and is widely used for industrial machine safety protection.
Key Benefits
▶Greatly reduce wiring man-hours: Only 5 wires for transmitter and receiver respectively to complete wiring. Wiring workload is comparable to area sensors, allowing simple safety countermeasures for machinery.
▶Easy optical axis alignment: At detection distance of 3m, the effective opening angle of transmitter is within ±5°. Compared with Type4 light curtain, optical axis alignment becomes simpler and installation is much easier.
▶Shorter safety distance calculation: All models of SF2C series have a unified 20ms response time. There is no need to calculate safety distance based on different optical axis quantity.

FAQ
Q: How does the optical axis alignment design benefit field installation?
A: At 3 meters detection distance, the transmitter has an effective opening angle within ±5°. Compared with Type4 safety light curtains, it is much easier to align optical axes during installation, saving adjustment time for technicians.
Q: What is the benefit of unified response time for all models?
A: All SF2C models feature a fixed 20ms OFF response time. Engineers no longer need to recalculate safety distance according to different optical axis numbers, which simplifies safety assessment and mechanical design work.
Q: What performance does the IP67 slim housing offer?
A: With new manufacturing technology, the miniature resin housing reaches IP67 IEC protection rating. It can resist dust and splash water inside production workshops, ensuring stable long-term operation under common industrial conditions.
Q: What output selections are available for this safety light curtain?
A: Two output versions are provided, including PNP open collector transistor and NPN open collector transistor. Customers can select the matching output type according to their control system requirements.
