Configured for optical presence detection and hazardous area perimeter guarding in automated machinery enclosures, the Omron F3SJ-E0625N25 (F3SJ-E Safety Light Curtain) provides direct physical/electrical execution.

Model Number Code Structure

• F3SJ: Identifies the Omron compact functional safety light curtain series.
• E: Specifies the Easy type functional classification with fixed NPN output logic.
• 0625: Designates a protective height metric of 625 mm.
• N: Indicates NPN transistor output configuration.
• 25: Represents a 25-mm beam pitch resolution designed for hand detection.

Physical & Electrical Specifications

Deterministic Safety Logic & Controller Integration

The safety light curtain array emits 870 nm infrared light beams across a 30-channel matrix to execute real-time optical interruption monitoring. Internal CPU processing evaluates cross-talk suppression and beam alignment status without external control units. Operating on EtherNet/IP deterministic networks or direct safety I/O backplanes, the unit maintains fast response times and firmware flash compatibility, preventing machine start cycles during light beam occlusion.

Mounting Architecture & Electrical Wiring Guidelines

Physical Alignment & Mechanical Mounting

• Secure the emitter and receiver units strictly parallel to each other on rigid structural frames using the provided mounting brackets.
• Ensure the optical axis covers the entire 625 mm hazard clearance area without optical reflections from nearby metallic surfaces.

Power Supply & Output Connection

• Connect a SELV/PELV certified 24 VDC external power supply to both the emitter and receiver heads.
• Route the NPN safety output lines directly to safety relay units or functional safety PLC inputs.

Cable Routing & Noise Mitigation

• Keep emitter and receiver cables separated from high-voltage motor drive conductors and AC supply wiring.
• Connect cable shielding to the main enclosure ground bus to guarantee electromagnetic compatibility.
