The protective height of 1905mm covers a full standing operator's reach zone, and the 20mm beam pitch gives you 94 individual beams across that height, so there are no gaps a hand could slip through undetected. The operating range spans 0.2m to 7.0m, which suits it for guarding the front of a machine cell or a conveyor access point where the receiver can be mounted a few meters away. The 24VDC supply is standard for safety circuits, and the IP65 rating means the housings and optics withstand washdown — suitable for food-and-bev lines or any environment where hoses are used for cleaning. Built-in blanking and muting functions let you configure the curtain to ignore fixed obstructions (like a machine frame) and to temporarily suspend the safety output during a material pass-through cycle. That saves you from needing an external safety controller for simple muting applications. Mount the emitter and receiver on opposite sides of the hazard zone, aligned so the 94 beams form an uninterrupted plane. The 1905mm protective height and 7.0m maximum range cover most reach-in guarding applications around presses, assembly stations, and packaging machinery. The IP65 housings tolerate direct spray, so you can mount them inside a washdown cell without adding protective shrouds.","metaTitle":"Omron F3SJ-B1905N25 Light Curtain, 25mm Hand Protection, 190","metaDescription":"Omron F3SJ-B1905N25 safety light curtain, 25mm detection capability, 1905mm protective height, 94 beams, 20mm pitch, IP65, 24VDC.
