The Omron F3SG-4SRB0880-45 is a Type 4 safety light curtain from the F3SG-SR series, built for arm and foot protection with a 45 mm detection capability. That 45 mm resolution means it catches a hand or forearm reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits press brakes, assembly stations, and robotic cells where operators reach into the danger area. The 880 mm protective height covers a typical standing operator's reach zone; with 22 beams at 40 mm pitch, the curtain spans 0.3 m to 20.0 m operating range, giving flexibility for both compact and wide-access guarding.
Ratings and fit
Runs on 24 VDC, standard for safety circuits. The IP65/IP67/IP67G rating means the sensor body and optics withstand washdown and oil exposure — suitable for food-and-bev lines and machining centers where coolant mist is present. The IP67G variant adds oil resistance, a common spec for automotive powertrain environments. Operating temperature from -30°C to 55°C covers unheated warehouses and freezer tunnels. Built-in blanking and muting functions let you ignore fixed obstructions (like a machine frame) or temporarily bypass the curtain during a workpiece pass-through. That reduces false trips without external controller logic.
