Description

Designed for reliable machine safeguarding, the Omron F3SJ-E0305N25 functions as a Type 4 safety light curtain engineered for hand detection in hazardous industrial environments. This unit provides a 305 mm protective height with a 25 mm detection capability, utilizing a 14-beam infrared optical grid to monitor intrusion fields. Operating on an NPN output configuration, the sensor system integrates seamlessly with standard control architectures and safety relays.

The F3SJ-E series features a streamlined, "easy" design paradigm that simplifies mounting, wiring, and overall system commissioning. With an operational range spanning from 0.2 to 7 meters, this light curtain is highly adaptable to space-constrained machinery and medium-range industrial workcells. Its IP65-rated enclosure ensures sustained optical alignment and environmental resilience against dust and water jets in manufacturing spaces.

Technical Specifications

Installation Guidelines

• Safety Distance: Ensure the unit is installed at a calculated safety distance from the hazard zone in compliance with ISO 13855 / ANSI B11.19.
• Alignment: Align the emitter and receiver optics until the integrated LED indicators confirm optimal signal reception across all 14 beams.
• Power & Grounding: Power the device using a stabilized SELV/PELV 24 VDC power supply. Route safety output cables away from high-voltage motor lines to prevent electromagnetic interference.
• Environmental Consideration: Avoid installation directly adjacent to highly reflective surfaces that could deflect the optical paths and bypass safety detection.
