The Omron F3SG-4RE1230P30 is a type-4 safety light curtain from the F3SG-RE series, rated for hand and arm detection with a 30mm detection capability. It provides a protective height of 1230mm across 60 beams at a 20mm beam pitch, covering an operating range from 0.3m to 20.0m. This unit operates on a 24VDC supply and carries an IP67 ingress protection rating, making it suitable for environments where dust tightness and temporary water immersion are concerns.
The 30mm detection capability means the curtain reliably detects a 30mm-diameter opaque object anywhere in the field — this is the standard threshold for hand/arm protection per IEC 61496-2. The 1230mm protective height defines the vertical zone that is guarded; for a machine opening or hazard area, the curtain must overlap the hazard by at least the required safety distance (calculated per ISO 13855 from the stopping time and approach speed). The 20mm beam pitch gives 60 beams, which provides a dense enough grid to catch a hand without excessive blanking. The operating range of 0.3m to 20.0m covers both close-in access and longer spans across a conveyor or press opening. The IP67 rating confirms the emitter and receiver can be washed down or exposed to coolant splash without ingress — relevant for food, automotive, or machining cells.
