That 25 mm figure is the minimum object size the curtain reliably catches — anything smaller could pass through undetected. For a point-of-operation guard, this means the curtain stops the machine before a hand or finger reaches the hazard zone, matching the resolution required by IEC 61496-1 for finger/hand detection at typical reach-through distances. The 1420 mm protective height and 20 mm beam pitch give 71 beams across the guarded opening. The 20 mm pitch is the spacing between adjacent beams; combined with the 25 mm detection capability, it sets the curtain's ability to resolve small objects. The 0.2 m to 9.0 m operating range covers most machine guarding layouts — from tight press-brake applications out to wider perimeter zones. ## Deployment context: where the IP65 and features matter Rated IP65 — dust-tight and protected against water jets — so the sensor heads and optics handle washdown environments typical in food processing, packaging lines, and machining cells where coolant mist or hose-down cleaning is routine. The 24 VDC supply is standard for safety circuits; plan for a dedicated safety-rated power supply if the control cabinet doesn't already provide one. Built-in blanking and muting functions are on-board, not add-on modules. Blanking lets you mask fixed obstructions (like a machine frame member) within the guarded area without disabling the entire curtain. Muting temporarily suspends the safety output during a defined material pass-through cycle — useful on conveyor infeed/outfeed stations where the product itself must break the beam without stopping the line. These are configured via the controller, not hardware jumpers.","metaTitle":"Omron F3SJ-A1420P25-TS Light Curtain, 25mm Detection, 1420mm","metaDescription":"Omron F3SJ-A1420P25-TS safety light curtain. 25 mm hand detection, 1420 mm protective height, 20 mm beam pitch, 71 beams, 9 m range.
