Duty envelope and family slot
The 1FK2104-6AF00-2MB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 servomotor family built for SINAMICS S120 drive line-ups, delivering M0 = 3.2 Nm with PN = 1 kW at nN = 3000 rpm on a 380-480 V bus (and PN = 0.5 kW at nN = 1500 rpm on a 200-240 V bus), which puts it squarely in the high-dynamic / short-stroke machine-tool and packaging axis class rather than the constant-torque conveyor class. Feedback is an absolute encoder AM22DQC — 22-bit single-turn plus 12-bit multiturn — resolved through a DRIVE-CLiQ M17 plug, so the motor carries its own electronic nameplate into the SINAMICS S120 and auto-configures on plug-in rather than needing a separate commissioning download.
Mechanical side: shaft, sealing, power lead
The shaft is a cylindrical D14 x 30 mm stub — no keyway — so coupling selection has to be a clamping or friction-fit element rather than a keyed coupling; the front face sealing rating is IP64, meaning dust-tight and resistant to splashing water but not a washdown-rated enclosure end. The power connector is size M17, sized for the 1 kW continuous rating on the 380-480 V bus; both signal (DRIVE-CLiQ) and power leads exit the same housing family, keeping the cabinet-side cable gland set to a single M17 spec.
Compliance set and admin codes
Siemens has held the 1FK2104-6AF00-2MB0 in compliance with the RoHS substance restrictions since 01-07-06 and supplies REACH Article 33 candidate-list disclosure on request, which is the documentation an Obsolete Parts Hunter typically needs to keep a machine file current. The piece carries Group Code R220 and Product Group 9021, the Siemens-internal admin keys a maintenance clerk uses to map the order code against the MRP master and the spare-parts catalogue (Product class C — produced to order, non-returnable for credit).
Carton contents
One piece ships per Quantity Unit, packaged at 452.00 x 250.00 x 267.00 mm — a single-motor carton with no separate accessory pack called out on the spec line, so any coupling, feedback cable extension, or SINAMICS mating connector is a kitting decision that has to be added to the BOM before the tech walks out the door.
Production status and supply posture
Lifecycle stage reads as current with the part marked Active, and the export classification is AL:N / ECCN:N_CNDU — no licence trigger for routine cross-border industrial shipment.
