The Omron F3SG-4SRB0280-85 is an active-production safety light curtain from the F3SG-SR series, with a detection capability of 85mm and a protective height of 280mm. It operates on a 24VDC supply and covers an operating range from 0.3m to 20.0m, making it suitable for point-of-operation guarding on larger machinery where hand or body detection is required.
The 85mm detection capability means this curtain reliably detects objects of that diameter or larger — sized for hand or torso detection, not finger. The 280mm protective height defines the guarded zone; pair it with a controller that matches the beam count (4 beams at 80mm pitch,). The IP65/IP67/IP67G rating covers dust-tight, temporary immersion, and oil-resistant environments — the G suffix indicates oil resistance, which matters in machining or press areas with coolant mist.
