What the M0 and dual voltage rating mean on this shaft
The 1FK2104-5AK00-2SB0 is a SIMOTICS S-1FK2 HD synchronous servo in the 1FK2 family for SINAMICS S120, with a stall torque M0 of 2.4 Nm and a rated power PN of 1.07 kW at 6000 rpm on a 380-480 V supply, or 0.75 kW at 3000 rpm on a 200-240 V supply — the dual rating is the same motor recharacterised for the two common industrial bus voltages rather than two different windings.
Encoder, feedback connector, and the drive side of the pair
Feedback is a single-turn 22-bit absolute encoder (AS22DQC), terminated through the DRIVE-CLiQ M17 plug — DRIVE-CLiQ is the digital motor-to-drive link used across the SINAMICS S120 platform, so the encoder data, motor nameplate, and electronic rating plate all pass over one cable back to the drive. Power is brought in through the M17 power connector, sized for the 1FK2 frame; the encoder and power connectors are physically separate so a swap during a fault on the feedback cable does not disturb the power leads.
Mechanical integration: shaft, sealing, and cabinet placement
The shaft is a cylindrical D14 x 30 mm stub, the standard 1FK2 high-dynamic frame dimension for coupling to a gearbox or directly to the load — a keyway or feather-key option is a separate order code, so confirm the BOM position against the coupling choice before specifying. IP64 means the motor body resists dust ingress and splashing water from any direction but is not rated for high-pressure washdown; in food-and-beverage or outdoor exposure, plan for a shroud or move to an IP65/IP67 variant in the same family.
Compliance and administrative ordering data
The motor is RoHS-compliant since 01-07-06 and is subject to REACH Art. 33 duty to inform — for EU shipments the SVHC declaration on the shipment documentation should accompany the unit. Administrative ordering data: Group Code R220, Product Group 9021, packaging quantity 1 piece, export-control class AL:N / ECCN:N_CNDU (no special export licence required).
Production status and how to land one on the BOM
The 1FK2104-5AK00-2SB0 is listed as active under the Siemens lifecycle; the product class is C — manufactured to order, non-returnable — so a min/max spares position must be sized against actual consumption rather than against distributor stock.
