The Omron F3SG-4SRA1120-25 is a Type 4 safety light curtain from the F3SG-SR series, rated for hand detection with a 25 mm detection capability. It projects 56 beams at a 20 mm pitch over a 1120 mm protective height, covering an operating range from 0.3 m to 20.0 m. This unit is active in production and sourced to order.
The 25 mm detection capability sets this curtain for hand and finger safety applications — it catches a 25 mm diameter object anywhere in the field. The 1120 mm protective height and 20 m range suit it for guarding a single machine access point or a conveyor zone up to that width. The IP65/IP67/IP67G rating means it handles washdown environments and oil exposure; the IP67G variant adds resistance to oil and coolant, common in machining centers. Blanking and muting functions are built in, so the curtain can tolerate fixed obstructions (like a machine frame) or temporarily ignore the beam for a workpiece pass-through without disabling the safety output. That saves an external bypass module.
