What this curtain is rated for
The F3SG-4SRB0960-14-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 single finger before it reaches the danger zone — not just a hand or arm. The 10 mm beam pitch and 95 beams give you a 960 mm protective height, sized for a typical vertical guarding zone on a machine access point. Operating range runs from 0.3 m out to 10.0 m, so it works both close-coupled against a press and across a wider cell entry. Blanking and muting functions are built in — blanking lets you ignore a fixed obstruction (like a fixture) in the field, and muting suspends the safety output during a controlled material pass. Both are standard, no extra module needed. Supply is 24 VDC, which is the standard for safety controllers and most PLC safety inputs. The enclosure carries IP65/IP67/IP67G — dust-tight, protected against temporary submersion, and with oil resistance. That IP67G spec (the G stands for oil-resistant) matters if this curtain sits near lubricated presses or machining centers where coolant mist and oil splash are daily.
The 960 mm protective height covers a typical machine access opening. The 14 mm finger detection meets the required resolution for point-of-operation guarding per ISO 13855 when the minimum distance from the hazard is calculated correctly. Operating temperature from -30°C to 55°C covers unheated warehouses and hot factory floors alike.
