The Omron F3SG-4SRA0720-14-F is a Type 4 safety light curtain from the F3SG-SR series, built for finger detection at 14 mm resolution. That 14 mm detection capability means it catches a finger reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits press brakes, assembly stations, and robotic cells where hand access needs guarding without a physical barrier. Protective height is 720 mm, covered by 71 beams at a 10 mm pitch. Operating range stretches from 0.3 m out to 10.0 m, which gives flexibility for both tight machine guarding and wider access areas.
What the ratings mean for fit
The 14 mm detection capability is the headline: it resolves a 14 mm object anywhere in the field. That's finger protection, not hand (30 mm) or body (50 mm) — so if your risk assessment calls for finger-level guarding, this is the resolution tier you need. The 10 mm beam pitch gives the density to catch smaller targets consistently. IP65/IP67/IP67G ingress protection means the sensor body and optics withstand washdown — suitable for food-and-bev lines or machining centers where coolant spray is routine. The IP67G suffix adds oil resistance, so it holds up in greasy environments like press shops. Operating temperature from -30°C to 55°C covers cold storage areas and unheated factory floors. The 24 VDC supply is standard for safety circuits; no special power rail needed.
Where it is used
Safety light curtains of this class are used to guard hazardous machinery — presses, cutters, robots, packaging lines — by creating an invisible detection field that stops the machine when interrupted. The F3SG-4SRA0720-14-F, with its blanking and muting functions, can handle pass-through applications where material needs to move through the field without tripping the stop.
