Servo motor identity and duty envelope
The Siemens 1FK2104-6AF00-0SB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family, sized for SINAMICS S120 drive commissioning — PN 1 kW at nN 3000 rpm on a 380-480 V bus and PN 0.5 kW at nN 1500 rpm on 200-240 V, so the same winding covers both the European 400 V class and the North American 230 V class without a re-rate. Stall torque is M0=3.2 Nm with a cylindrical shaft D19x40 mm and an absolute encoder single-turn 22-bit (AS22DQC) — the 22-bit resolution gives 4,194,304 counts per turn, which is the resolution ceiling the SINAMICS controller will close position loops against before any gearing downstream. The feedback path is DRIVE-CLiQ over the M17 plug; the power connector is a separate size-M17 — keeping encoder and power on different keyed connectors prevents a cross-mate at the cabinet, which matters when the motor lands in a high-density SINAMICS S120 motor module bay.
Mechanical and environmental envelope
Degree of protection is IP64 — dust-tight and resistant to splashing water from any direction, so the motor body tolerates typical cabinet-near plant air but is not rated for direct washdown; mount it where the shaft seal faces the gearbox, not the floor drains. Shipping crate is 452.00 x 250.00 x 267.00 mm at one piece per pack — single-unit handling applies, and the packaging dimensions tell you the cell needs to accept a roughly half-metre box at goods-in for receiving inspection before the motor goes to staging.
Compliance posture and commercial classification
RoHS compliance is in force since 01-07-06 and REACH Art. 33 candidate-list information is supplied with the product — the substance-restriction declarations a buyer on a European build expects to see in the declaration pack are covered. Export Control Regulations show AL:N / ECCN:N_CNDU — no special export licence routing required for the standard shipment, which keeps the cross-border paperwork inside the routine commercial-invoice flow. Group Code R220 and Product Group 9021 are the internal ordering identifiers Siemens uses for this line — match both against the PO line so the BOM ties to the correct factory order code and not a visually similar 1FK2 variant.
Lifecycle and supply
Lifecycle stage is current and product status is Active — the part is in production and not on a phase-out track, so a BOM line carrying 1FK2104-6AF00-0SB0 is safe against an LTB window landing mid-project. Because the product class is built-to-order, availability is quoted against the requested quantity and the current factory load at the time of RFQ — independent distribution channels pull from Siemens' configured production run rather than holding finished inventory.
