Omron F3SG-SRB Series Light Curtain Receiver, Sender, 50 Beam(s), 25 mm Resolution

This light curtain is a safety sensing device designed to detect intrusion into hazardous zones and stop machinery operations where human presence is undesirable. It functions as a receiver within a protective safety system, providing short-range detection across a 1m protective height and supporting industrial guarding tasks where rapid interruption of hazardous motion is required.

• 50 beams provide dense detection and reduce bypass risk
• 25mm beam resolution enables fine object discrimination
• 0.3m minimum scanning distance permits close-proximity protection
• 20m maximum scanning distance supports long-range coverage
• 13 ms maximum response time reduces stopping delay for machinery
• 28.8V maximum supply simplifies integration with low-voltage systems

• Suitable for safeguarding robotic workcells with close access
• Ideal for conveyor end-of-line personnel protection
• Used with press and stamping machines for area intrusion detection
• Can be used for perimeter monitoring of production cells
• Suitable for short-range access control in assembly stations

When one or more of the 50 optical paths are broken, the receiver reports an interruption condition and outputs a safety signal within the specified 13 ms response window to initiate machine stoppage.

The sensor is rated to operate from a minimum separation of 0.3 m, so mounting should ensure the nearest protected zone boundary is at or beyond this short-range limit.

The unit must be powered within its maximum supply voltage rating of 28.8V to maintain specified detection and response characteristics.

The optical spacing delivers 25mm resolution, allowing detection of relatively small intrusions across the protective height.
