What It Is and What It Does
The Omron F3SJ-A0470N30 is a safety light curtain from the F3SJ-A series, designed for hand and arm protection on machinery. It uses 19 beams at a 25mm pitch to create a 470mm protective height, with a 30mm detection capability — meaning it reliably catches a hand or arm reaching into a hazard zone, which is the standard for finger and hand safety per IEC 61496. Rated for a 0.2m to 9.0m operating range, it works across a wide span of machine guarding applications, from tight press enclosures to longer conveyor access points. The 24VDC supply is standard for safety circuits, and the IP65 rating means the housing and optics resist dust and water jets — suitable for washdown environments in food processing or machining lines.
Key Features for the Install
Blanking and muting functions are built in, allowing the curtain to ignore stationary objects (like a fixture) or temporarily bypass during a material pass cycle. This saves wiring external bypass relays. Operating temperature range of -10°C to 55°C covers most indoor plant floors, but watch the upper end near ovens or dryers — derating isn't specified, so keep it clear of heat sources.
Sourcing and Lifecycle
For BOM-freeze or compliance documentation needs (RoHS, REACH, UL, IEC), the manufacturer provides declarations with the shipment. We source it against an RFQ for your line.
