The Omron F3SG-4SRB1200-14 is a Type 4 finger-protection light curtain from the F3SG-SR series, rated for 14 mm detection capability and a 1200 mm protective height. It operates on a 24 VDC supply and spans a 0.3 m to 10.0 m operating range. The 119 beams at 10 mm pitch give it the resolution to detect fingers, making it suitable for access guarding around automated cells or press brakes. The enclosure carries IP65/IP67/IP67G ratings, meaning it handles dust ingress, oil exposure, and temporary submersion — a practical choice for washdown zones or machining environments where coolant mist is present.
The 14 mm detection capability is the key spec for finger protection — it defines the smallest object the curtain reliably catches. If your application requires hand or palm detection, a 30 mm or 40 mm beam pitch would suffice, but for finger safety this is the correct resolution. The 1200 mm protective height covers a typical machine opening; verify that the guarded opening height does not exceed this value, as the curtain must overlap the hazard zone by at least the required safety distance. Blanking and muting functions are built in, which allows the curtain to ignore fixed obstructions (like a work fixture) or to temporarily suspend detection during a material pass-through. These are configured via the controller, not the sensor head itself, so factor in the controller model when specifying the system.
