Omron F3SJ Series Light Curtain Receiver, Sender, 19 Beam(s), 30 mm Resolution

This light curtain is a receiver unit designed to perform personnel and machine safeguarding in industrial environments. It establishes a protective detection plane using multiple infrared beams to monitor access to hazardous areas, suitable for short-range installations requiring rapid interruption sensing and compact vertical coverage.

• Nineteen beams provide fine multi-point intrusion detection
• 30mm beam spacing enables precise presence discrimination
• 44 ms maximum response time aids rapid machine stoppage
• 24V maximum supply voltage supports common control systems
• 0.2-9m minimum to maximum scanning distance allows flexible placement
• Safety type 4 rating ensures high integrity for risk reduction

• Suitable for safeguarding access to press and stamping machinery
• Ideal for protecting robotic workcells and loading zones
• Used with conveyor infeed points to detect reaching hazards
• Can be used for perimeter protection on automated lines
• Used for short-range guarding where compact height is required

The receiver provides a protective height of 470mm, forming the active sensing aperture for detecting intrusions across its plane.

With 19 separate beams the unit reduces blind zones and improves object capture across the sensing plane, aiding consistent interruption detection.

The unit accepts up to 24V supply voltage, matching common industrial control voltages and simplifying connection to safety relay input circuits.

The minimum effective scanning separation is 0.2 m, permitting installation in confined or compact guarding layouts.
