Omron F3SJ Series Light Curtain Receiver, Sender, 14 Beam(s), 25 mm Resolution

This light curtain is a safety receiver designed to detect intrusions into hazardous zones and halt machinery where necessary. It operates as part of a protective sensing system, offering multi-beam detection across a guarded area with a compact protective height and versatile distance capability suitable for a range of industrial environments.

• Four-level safety category reduces risk in high-hazard applications
• Fourteen independent beams provide precise object detection
• 25mm beam spacing enables fine intrusion resolution
• Operates from a 24V supply for common industrial control systems
• Response time of 70ms supports rapid stoppage of equipment
• Scanning capability from 0.2-7m accommodates varied layouts

• Suitable for safeguarding access to production machinery
• Ideal for integration with automated packaging lines
• Used with conveyor guarding where limited height clearance exists
• Can be used for perimeter protection of robotic cells
• Useful for retrofit installations requiring a receiver-only unit

With 25mm beam spacing and 14 beams, the system detects intrusions approximately matching the beam resolution rather than individual pixel sizes.

The receiver functions correctly across a scanning range from 0.2m up to 7m, permitting placement close to or several metres from the paired transmitter.

It is intended to run on a 24V supply compatible with standard industrial control circuits and safety relays.

The device provides a maximum reaction interval of 70ms from detection to output, enabling prompt machine stoppage.
