What this motor is, and where it plugs in
The 1FK2104-5AK10-2MB0 is a SIMOTICS S-1FK2 HD servomotor from Siemens rated at M0 = 2.4 Nm, sized for the SINAMICS S120 drive line on a DRIVE-CLiQ M17 interface, and ships with a holding brake and an absolute encoder AM22DQC (22-bit single-turn + 12-bit multiturn) so the controller re-establishes axis position on power-up without a homing routine. Power is quoted in two operating windows — PN = 1.07 kW at nN = 6000 rpm on a 380-480 V bus, and PN = 0.75 kW at nN = 3000 rpm on a 200-240 V bus — so the same frame covers both the 230 V European and 400/480 V common-bus cabinets without rewinding or a different winding option.
Mechanical and connection stack a panel builder needs
The shaft is a plain cylindrical D14 x 30 mm stub and the housing carries IP64, meaning it is sealed against splash and dust ingress but not rated for hose-down — keep it behind the cabinet face or in a non-washdown zone of the machine. The motor carries both a power connector size M17 and a DRIVE-CLiQ encoder plug M17; on the SINAMICS S120 side these land on the matching Motor Module and the DRIVE-CLiQ port, so the feedback loop closes natively without an external SMC/SME module between the two. One piece ships in a 452.00 x 250.00 x 267.00 mm pack — plan the inbound-receiving cart space for single-unit deliveries when an MRO spare is being kitted alongside the BOM drop.
Compliance and trade paperwork that follows the crate
Compliance with the substance restrictions per the RoHS directive has been in force since 01-07-06, and the supplier carries a Reach Art. 33 duty-to-inform obligation against the current candidate list — request the latest Reach declaration against your PO date before the goods clear customs if your site is EU-bound. Export classification is AL:N / ECCN:N_CNDU, which keeps the part out of the US export-licence queue for most commercial destinations but still requires the standard end-use statement on the commercial invoice. Siemens lists the product under Product Group 9021 and Group Code R220, and the product class is class C — manufactured or produced to order, not returnable for credit. That class-C tag is the lever that lets a sourcing desk push for replacement-window warranty through the OEM channel rather than the distributor return-and-refund path.
Production status and how the RFQ line moves
Procurement-wise this is a build-to-order servo: BOM quantities are quoted against the RFQ, lead time and price-break ladder confirmed at quote, and a single-piece MOQ baseline flows from the Quantity Unit field. Line-down spares are kitted against the same RFQ path; no standing shelf stock is implied.
