The Omron F3SJ-E0625P25 serves as the primary F3SJ-E Safety Light Curtain utilized to execute machine guarding optical sensing and interruption signal switching across safety controller platforms.

Part Number Structure & Model Decoding

The internal cataloging format defines functional classification, protective height, output circuit configuration, and resolution spacing across the series matrix:

• F3SJ-E: Easy-type base series providing core optical presence detection without complex software configuration.
• 0625: Specifies a 625 mm vertical protective height.
• P: PNP open-collector output circuit configuration.
• 25: Indicates 20 mm optical beam gap yielding a 25-mm diameter detection capability.

Technical Data Sheet

EtherNet/IP & Deterministic Bus Operations

The safety sensor array interfaces directly with safety input channels to maintain deterministic response timing across Profinet and EtherNet/IP networks. Optimized firmware flash compatibility ensures synchronized status reporting to PLC safety CPUs, maintaining high I/O density scaling and predictable safety-off trip times without introducing communication delay onto the fieldbus network.

Field Installation & Wiring Guidelines

Physical Alignment & Assembly

• Install emitter and receiver on rigid, vibration-free structural profiles at matched heights.
• Ensure full parallelism between optical faces using line-of-sight laser tools before tightening brackets.
• Maintain the optical distance strictly within the specified 0.2 to 7 m operating range.

Power Supply & Signal Shielding

• Connect the system exclusively to a regulated SELV/PELV 24 VDC source with less than 10% ripple.
• Isolate output and power cables from AC drive outputs, motor cables, and high-frequency noise sources.
• Ground the aluminum housing enclosure and cable shielding to a low-impedance earth terminal to suppress EMI.

Technical Questions & Troubleshooting

• Q: What power supply parameters are required for reliable sensor operation?

  A: The device requires a SELV/PELV 24 VDC power supply with +/-20% voltage tolerance and maximum peak-to-peak ripple under 10% to prevent internal reset conditions.

• Q: Is live hot-swapping permitted on this light curtain model during operation?

  A: No, hot-swapping is prohibited. Always de-energize the 24 VDC power supply prior to disconnecting or reconnecting sensor cables to prevent short-circuit output damage.

• Q: What is the exact detection capability provided by this 30-beam unit?

  A: The 20 mm beam gap delivers a 25-mm diameter detection capability, which provides certified hand and arm protection across the full 625 mm protective height.

• Q: How do the PNP safety outputs function under uninterrupted conditions?

  A: In a clear optical state, dual PNP transistors source 24 VDC actively to the connected safety relay or controller input terminals.

• Q: What is the no-load current consumption for this specific beam configuration?

  A: At 30 beams, the emitter consumes a maximum of 57 mA, while the receiver consumes up to 47 mA from the 24 VDC power line under no-load conditions.

• Q: What ingress protection rating applies to the sensor enclosure?

  A: The sensor enclosure meets IP65 standards, offering protection against total dust ingress and low-pressure water jets from any direction.

• Q: How does the system handle high-frequency electrical noise from surrounding machinery?

  A: Internal optical filtering combined with proper single-point shield grounding prevents electromagnetic interference from causing false output trips.

• Q: What optical emitter technology is utilized in the transmitter head?

  A: The emitter head houses an array of infrared LEDs operating at an emitted peak wavelength of 870 nm to send synchronized pulses to the receiver.
