What it is and where it fits
The Siemens 3SF5900-0BA is a cable set designed for AS-i F-slave devices, used as a component within AS-i enclosures — both plastic and metal types. It's the wiring link between the AS-i bus and the slave module, carrying power and data in a single flat cable. Rated IP67, so the connector end and the cable entry are sealed against dust ingress and temporary immersion — suitable for washdown zones on packaging lines or in food-grade areas where hose-down cleaning is routine. Operating temperature range of -25 to +70 °C covers most indoor industrial environments and cold-store applications down to freezer temperatures.
Lifecycle and sourcing reality
RoHS compliance is documented with a substance prohibitance date of 07/01/2006, confirming the part meets the original EU RoHS directive. No REACH or UL listing appears in the record for this specific cable set.
What it connects to
This cable set is specific to AS-i F-slave modules — it is not a general-purpose sensor cable. The fastening method is listed as miscellaneous, meaning it uses the AS-i standard piercing connection rather than a screw or spring terminal. No DIN-rail clip or panel-mount bracket is involved; the cable terminates at the slave module inside the enclosure. The reference code per IEC 81346-2 is W, which designates a cable or wiring assembly in the standard functional labeling system — useful when generating panel documentation or EPLAN tags.
