Omron F3SG Series Light Curtain Sender, Receiver, 40 Beam(s), 30 mm Resolution

This light curtain provides non-contact safeguarding for machinery by detecting intrusions into hazardous zones. It comprises a transmitter and receiver pair that create a multi-beam protective field suitable for industrial environments. The device is intended to interrupt hazardous motion quickly while fitting into installations that require a compact protective height and flexible reach.

• 40 beams deliver fine object detection and improved area coverage
• 30mm beam resolution enables detection of small obstructions
• 0.3-10m scanning distance supports close-range to extended deployments
• 8 ms response time minimises stopped-machine exposure during intrusion
• 24V supply compatibility eases integration with common control systems
• Safety type 4 classification permits use where high integrity is required

• Suitable for safeguarding access to automated press operations
• Ideal for perimeter guarding on robotic workcells
• Used with conveyor infeed zones to detect operator entry
• Can be used for loading doors requiring reliable presence detection
• Used for machine-feeding stations where fast stoppage is necessary

It uses separate sender and receiver units aligned across the protected area, with a low-voltage 24V supply for control wiring and optical synchronisation between units.

With a 30mm beam spacing and 40 distinct beams, it detects objects approximately equal to or larger than the beam resolution across the entire protected height.

The device interrupts output within 8 ms of beam interruption, allowing designers to account for short detection-to-stop intervals when calculating stopping distances.

The system can span up to 10m in protective width, enabling a single sender/receiver alignment to cover wide openings.
