Omron F3SG-RE Series Light Curtain Sender, Receiver, 79 Beam(s), 14 mm Resolution

This light curtain is a safety sensor designed to detect intrusions into hazardous areas and stop machinery accordingly. It is intended for industrial machine guarding where a compact, easy-to-install presence-detection device is required. The product suits short- to medium-range installations and provides a simple ON/OFF detection solution with rugged connectors and alignment aids for field setup.

• 14mm beam resolution reduces missed finger/part detection risk
• 79-beam array increases coverage for wide protective zones
• 800mm protective height enables single-unit guarding of mid-height openings
• 0.3m short-range start improves protection near the emitter
• 10m maximum scanning distance allows long-reach guarding layouts
• 24V supply with M12 connector simplifies industrial wiring

• Suitable for safeguarding press feed and pick-and-place zones
• Ideal for presence detection on conveyor infeed and outfeed lines
• Used for access control on automated assembly stations
• Can be used for perimeter protection around robotic workcells
• Used with safety controllers for machine stop on entry detection

The devices use a 4-pin M12 connector and standard wiring with power, 0V and two OSSD safety outputs

The unit operates between −10°C and 55°C and withstands humidity from 35% to 85% non‑condensing while offering IP65/67 protection against dust and water.

The detection chain offers ON-to-OFF switching in 5–15ms and OFF-to-ON recovery in 25–75ms, with a specified maximum system response time of 145ms under defined configurations.

The design includes torsion-resistant housings, simple click-style cable connections for correct torque and IP67 sealing, Plus QR-code reference for troubleshooting and alignment aids such as an optional laser pointer.

Safety outputs are provided as two transistor OSSDs available in PNP or optional NPN variants with a maximum load current of 300 mA per output to Interface with common safety controllers.
