What the 14 mm detection means for fit
The F3SG-4SRB0400-14 is a Type 4 safety light curtain from the F3SG-SR series, built for finger protection with a 14 mm detection capability. That 14 mm beam pitch catches fingers 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 400 mm protective height and 39 beams give a 400 mm sensing field; the 0.3 m to 10.0 m operating range covers short-reach to mid-span guarding without external mirrors. Runs on 24 VDC, standard for safety circuits. The IP65/IP67/IP67G rating means the sensor body and optics withstand washdown — the IP67G adds oil resistance, making it suitable for food-and-bev lines or machining centers with coolant mist. Operating temperature from -30°C to 55°C covers freezer environments and unventilated enclosures.
Built-in blanking and muting
Blanking and muting functions are onboard — no external controller needed for fixed or floating blanking (ignoring a stationary object in the field) or muting (temporarily overriding the curtain during a material pass). This simplifies wiring and saves panel space for applications like palletizers or conveyor infeed where workpieces break the beam intentionally.
