Omron F3SJ-B1665N25 Light Curtain, 25mm Hand Protection, 166

Its 25 mm detection capability means it reliably catches a hand or finger reaching into the guarded zone — that's the standard finger/hand-protection threshold per IEC 61496-1. The 1665 mm protective height, built from 82 beams at a 20 mm pitch, covers a full standing-height access opening; you size the curtain so the protected height exceeds the reach distance to the hazard. The 0.2 m to 7.0 m operating range gives flexibility for machine guarding layouts — mount the emitter and receiver up to 7 m apart, with a minimum 0.2 m gap to avoid optical short-range instability. IP65 (dust-tight and water-resistant) means the sensor housings handle washdown environments, so this curtain suits food-processing or wet-area machine guarding without an extra enclosure. Supply is 24 VDC nominal, standard for safety circuits in a control panel. Built-in blanking and muting functions let the curtain ignore fixed obstructions (blanking) or temporarily suspend guarding during a material pass-through (muting), which avoids nuisance trips on automated lines. Operating temperature spans -10°C to 55°C, covering most factory-floor conditions without derating.
