Omron F3SJ Series Light Curtain Receiver, 18 Beam(s), 20 mm Resolution

This light curtain is a safety sensing device designed to detect obstructions in machinery access zones and halt hazardous motion. It operates as a receiver within a protective sensing system and is intended for short-range safeguarding tasks where rapid detection and shutdown are required. The unit connects via screw terminals and is powered from a low-voltage DC supply, making it suitable for integration into industrial control circuits.

• 18 beam array delivers fine-zone interruption detection
• 20mm beam spacing improves hand and finger detection
• 0.2-7m operating range supports compact layouts
• 70ms response time enables fast fault reaction
• 24V DC supply compatibility simplifies control integration
• Type 4 safety classification meets high-risk application needs

• Suitable for guarding access on assembly-line machines
• Used with robotic cells requiring presence detection
• Ideal for press or cutting-station perimeter safeguarding
• Can be used for operator access control on conveyors
• Used for packaging machinery requiring rapid stoppage

Connections are made via screw-type terminals, allowing conventional field wiring to low-voltage control systems.

The receiver can detect beams at a minimum separation of 0.2m from its paired emitter, enabling close-proximity installations.

The device’s maximum response time is 70ms, which determines how quickly it signals a safety stop after beam interruption.

The receiver is constructed with a narrow 30mm profile and a height of 454mm, permitting installation where clearance is limited.

TUV, cULus, CE marked.
