The Omron F3SG-4SRB0600-25-F is a type-4 safety light curtain from the F3SG-SR series, rated for hand protection with a 25 mm detection capability. It projects 30 beams at a 20 mm pitch across a 600 mm protective height, covering an operating range from 0.3 m to 20.0 m. Powered by 24 VDC, the unit carries IP65/IP67/IP67G ingress protection — dust-tight, oil-resistant, and waterproof, including the IP67G variant for harsh washdown environments.
The 25 mm detection capability and 20 mm beam pitch are the deciding specs for hand-protection applications: this curtain catches a finger or hand entering the field, not just a torso. The 600 mm protective height defines the zone it guards — sized for a single access point or a small machine opening. With 30 beams, the resolution is fine enough to detect a hand at any point across the height, and the 0.3 m to 20.0 m range gives flexibility for both close-in and longer-reach guarding.
Integration notes
The F3SG-4SRB0600-25-F supports blanking and muting functions, which allow it to ignore fixed obstructions or temporarily bypass the field during a material feed cycle. These features are configured via the controller or external inputs — no mechanical masking needed. The IP65/IP67/IP67G rating means it can be mounted directly on a machine frame in a wet or oily environment without a secondary enclosure. Supply is 24 VDC, standard for safety circuits; plan for a dedicated safety relay or safety PLC input to handle the OSSD outputs.
