What this light curtain does
The Omron F3SJ-A1940P25-TS is a safety light curtain from the F3SJ-A series for hand protection. Its 25 mm detection capability, 20 mm beam pitch, and 97 beams provide a 1940 mm protective height. Rated for a 0.2 m to 7.0 m operating range, this curtain works in both tight machine guarding and wider perimeter setups. The 24 VDC supply is standard for safety circuits, and the IP65 rating means the housing and optics withstand washdown and dusty environments — suitable for food processing or machining lines where coolant mist is present. Built-in blanking and muting functions allow the curtain to ignore fixed obstructions (like a fixture) or temporarily bypass during material feed, which saves adding external bypass relays. Operating temperature spans -10°C to 55°C, covering most factory floor conditions without derating.
