Omron F3SG Series Light Curtain Receiver, Sender, 12 Beam(s), 25 mm Resolution

This light curtain is a safety receiver designed to detect intrusions into hazardous machine zones and halt motion accordingly. It operates as part of a safeguarding system, providing short-range protection with a compact housing suited to tight installations. The unit is intended for integration into industrial control circuits where reliable presence detection across a defined vertical area is required.

• Twelve independent beams give fine object discrimination
• 25mm beam spacing improves small-object detection
• Response time of 8ms supports rapid stop commands
• Operates from a 28.8V supply for low-voltage systems
• Detects targets from 0.3m for close-proximity sensing
• Effective protective span reaches up to 20m for wide coverage

• Suitable for safeguarding robot workcells with restricted access
• Ideal for press and cutting machinery perimeter protection
• Used with conveyor infeed points to detect hand intrusion
• Can be used for inspection stations requiring short-range detection
• Appropriate for packaging lines needing wide-area safeguarding

The array comprises 12 beams with 25mm spacing, enabling detection of relatively small objects crossing the protective plane.

The receiver has a compact rectangular housing measuring 32mm in width and 38mm in height, permitting installation in constrained spaces.

The system supports a scanning distance range from 0.3m up to 20m between sender and receiver for flexible layout options.

It requires a 28.8V supply, so designers should provide appropriate low-voltage power and consider wiring for safety category interfaces.
