What this light curtain covers
The F3SJ-E0225P25 is a 25 mm detection-capability safety light curtain from Omron's F3SJ-E series, designed for hand protection per the listed Protection class. Its 225 mm protective height and 10 beams at 20 mm pitch define the guarded zone — it catches a hand or finger reaching into the hazard area, not just a full-body presence. Operating range spans 0.2 m to 7.0 m, so it fits both tight machine guarding zones and wider access points. Powered by 24 VDC, standard for safety circuits in most control panels.
Where it goes and what it survives
Rated IP65 — dust-tight and protected against water jets — so it handles washdown environments in food processing, packaging, or general industrial lines where hose-down cleaning is routine. The 25 mm detection capability means it meets the finger-protection threshold per IEC 61496-1/2 for safety light curtains guarding reaching hazards. That 20 mm beam pitch gives the resolution needed to detect a hand before it enters the danger zone.
