Omron F3SG-SRA Series Light Curtain Receiver, Sender, 179 Beam(s), 14 mm Resolution

This light curtain provides optoelectronic presence detection for machine safeguarding in industrial settings. It operates as a receiver unit within a safety barrier arrangement, creating a protected vertical detection field to prevent access to hazardous areas. The device is intended for use where a compact, high-resolution sensor is required to monitor operator or object intrusion across a guarded aperture.

• 179 beams deliver dense coverage for fine object detection
• 14mm beam spacing enables detection of small targets
• 0.3-10m scanning range supports short to medium reach installations
• 18ms maximum response time permits rapid safety interruption
• Type 4 safety classification supports high-integrity applications
• 28.8V maximum supply allows integration with low-voltage safety circuits

• Suitable for safeguarding access to automated press lines
• Ideal for perimeter protection of robotic workcells
• Used with conveyors to detect product overhang or jamming
• Can be used for loading stations requiring fast stop response
• Used for gate monitoring where slim-profile receivers are needed

The unit is supplied in a 1800mm protective height format to match common reach profiles.

A maximum protective width of 10m can be established when paired with appropriate transmitters and alignment.

Detection is possible from 0.3m from the optical plane, enabling close-proximity safeguarding.

The compact 32mm housing width permits tight spacing on machine frames and narrow mounting rails.
