What the 25 mm Detection Capability Means for Your Guarding Layout
The Omron F3SJ-A1500P25 is a Type 4 safety light curtain from the F3SJ-A series, rated for hand protection with a 25 mm detection capability per the spec. That 25 mm figure is the minimum object size the curtain reliably detects — a finger or hand reaching past the plane triggers the safety output. The 1500 mm protective height and 75 beams at 20 mm pitch cover a full standing-height zone without gaps. Operating range spans 0.2 m to 9.0 m, so it fits both tight machine-loading stations and wider perimeter access points.
Blanking and Muting — When the Curtain Needs to Ignore Fixed Objects or Let Material Through
Built-in blanking lets you mask stationary machine parts (a clamp, a fixture) within the field without disabling the whole curtain — the beams around the object stay active. Muting function temporarily suspends the safety output when a workpiece enters the zone under controlled conditions, then re-arms once the part clears. Both features are configured at the controller level, not hardwired, which saves panel space and avoids external bypass relays.
IP65 and 24 VDC — Deployment Constraints for Washdown and Control Voltage
Rated IP65 — dust-tight and protected against water jets — so the emitter and receiver housings tolerate washdown in food processing or machining coolant environments. Supply is 24 VDC, which is standard for safety circuits tied to a safety PLC or relay module.
Lifecycle and Sourcing — Active Production, No End-of-Life Notice
The F3SJ-A1500P25 carries an active product status per the manufacturer's lifecycle record. No end-of-life notification or last-time-buy window is in effect.
