The Omron F3SG-4SRB0640-14 is a type-4 safety light curtain from the F3SG-SR series, built for finger and hand protection at machine access points. Its 14mm detection capability and 10mm beam pitch (63 beams) resolve a 14mm object across a 640mm protective height, covering the opening on smaller assembly stations or packaging machines. The 0.3m to 10m operating range gives flexibility for both reach-in guarding and perimeter applications within a cell.
The 14mm detection capability is the key fit parameter — it means the curtain catches a 14mm-diameter finger or tool before it reaches the hazard, which is the standard for finger protection per IEC 61496. The 640mm protective height defines the guarded zone; if your opening is taller, you stack multiple units or step up to a longer model in the same series. The 10m range is the maximum separation between emitter and receiver — adequate for most machine cells, but if your layout pushes beyond that, the curtain won't see the far end. IP65/IP67/IP67G means it handles washdown and oil mist; the IP67G variant adds oil resistance for cutting fluid environments.
Integration notes
The F3SG-4SRB0640-14 runs on 24VDC and includes blanking and muting functions, which let you ignore fixed obstructions (like a conveyor frame) or temporarily bypass the curtain during a material pass cycle without stopping the machine. These features are configured via the controller or software — no hardware jumpers. The IP67G rating is worth noting if the curtain sits near coolant spray; standard IP67 is fine for dust and hose-down, but IP67G adds the oil-resistance spec for machining centers.
