What the ratings mean for fit
The F3SJ-A0745P30 has a 30 mm detection capability for hand/arm protection. The 745 mm protective height covers a vertical zone with 30 beams at 25 mm pitch. Operating range is 0.2 m to 9.0 m. The IP65 rating means the emitter and receiver housings are dust-tight and protected against water jets — suitable for washdown environments in food processing or wet machining lines. The 24 VDC supply is standard for safety circuits, keeping it compatible with most safety relay or safety PLC inputs.
Deployment context
Mount the emitter and receiver on rigid brackets at either side of the hazard opening, aligned within the angular tolerance specified in the installation manual. The IP65 housings tolerate washdown, so this curtain fits on packaging lines, robotic cells, or assembly stations where coolant or cleaning sprays are present. The 0.2 m minimum range means it can guard a small press opening; the 9.0 m maximum covers a wide conveyor access point.
