Omron F3SG Series Light Curtain Sender, Receiver, 28 Beam(s), 30 mm Resolution

This light curtain provides non-contact presence detection for safeguarding access to hazardous machinery in industrial automation settings. It operates as a paired emitter-and-receiver protection device designed to interrupt motion when an object crosses its optical field, delivering a compact safeguarding solution for production lines and machine guarding applications.

• 28 beams deliver fine multi-point intrusion detection
• 30mm beam spacing enables small-object detection capability
• 0.3-20m sensing range supports short to long-distance setups
• 8ms response time minimises stoppage delay for faster cycling
• 28.8V maximum supply voltage allows integration with common control systems
• Type 4 safety classification provides high-integrity protective performance

• Suitable for perimeter guarding on automated assembly stations
• Ideal for preventing access to press and cutting equipment
• Used with robot cells for collaborative zone demarcation
• Can be used for conveyor line access control and e-stops
• Suitable for retrofitting compact machine enclosures

It comprises a sender and a receiver pair configured to face each other across the protected area and establish the sensing curtain.

A higher beam count increases the number of detection planes, reducing the chance of undetected entry by small objects or fingers.

The sensor heads have a slim 35mm cross-section to ease mounting in tight frames and uprights.

The active protective height produced by the installation is 590mm measured along the sensing axis.
