The Omron F3SG-4SRB0720-14-F is a type-4 safety light curtain from the F3SG-SR series, rated for finger detection with a 14 mm detection capability and a 720 mm protective height. It operates on a 24 VDC supply and is built to IP65/IP67/IP67G ingress protection, meaning it handles dust, oil, water jets, and temporary submersion in the field. The 10 mm beam pitch and 71 beams give it a resolution fine enough to detect a single finger, making it appropriate for applications where operator access near hazardous motion must be reliably interrupted. The operating range spans 0.3 m to 10.0 m, so it fits both compact machine cells and wider access areas.
Key ratings in context
The 14 mm detection capability is the spec that governs fit for hand/finger safety: it means the curtain will catch a 14 mm-diameter object anywhere in the field, which is the standard threshold for finger protection under IEC 61496. The 720 mm protective height defines the vertical zone covered — pair it with a transmitter and receiver of matching height to guard a single machine opening or a section of a larger perimeter. Blanking and muting functions are built in, so the curtain can tolerate fixed obstructions (blanking) or temporarily suspend the safety output during a material pass-through (muting) without needing an external controller. That saves panel space and wiring on automated lines where pallets or parts must cross the light curtain. The IP65/IP67/IP67G rating covers washdown environments: IP65 for dust and water jets, IP67 for temporary immersion, and IP67G adds oil resistance. This makes the unit suitable for food processing, machining with coolants, or outdoor installations where moisture and oil mist are present.
