Integrator's field note — what the ratings mean for fit
The Omron F3SG-4SRB0920-14-F is a Type 4 safety light curtain from the F3SG-SR series, built for finger detection at 14 mm resolution — that means it catches individual fingers reaching into the hazard zone, qualifying as finger-protection class per IEC 61496-1. The 920 mm protective height and 10 mm beam pitch give you 91 beams covering the full guarded opening; you size the curtain so the protective height exceeds the reach distance to the pinch point. Operating range spans 0.3 m to 10.0 m, so it works on a short press feed or across a wider robot cell. The 24 VDC supply is standard for safety circuits — just confirm your safety relay or controller can source the loop current. Blanking and muting functions are built in, meaning you can program fixed obstructions (like a part fixture) or temporarily bypass the curtain during a material-handling cycle without an external bypass module.
Environmental sealing — where this curtain lives
Rated IP65/IP67/IP67G — the G suffix means it passed Omron's oil-resistance test, so it holds up on machining lines with coolant mist or light oil spray. Dust-tight and waterproof to submersion depth, but the real differentiator is the oil resistance: standard IP67 curtains wick oil into the optics over time; this one doesn't. Operating temperature from -30°C to 55°C covers cold warehouses and warm factory floors without derating.
