Torque envelope and dual-voltage rating
The 1FK2104-4AF00-2SB0 is a SIMOTICS S-1FK2 HD servo motor in the 1FK2 family for SINAMICS S120 drives, rated M0 = 1.27 Nm with PN = 0.4 kW at nN = 3000 rpm on a 380–480 V bus and PN = 0.2 kW at nN = 1500 rpm on 200–240 V — the same frame covers both the 230 V and 400 V SINAMICS line inputs without a winding swap. The 22-bit single-turn absolute encoder (AS22DQC) feeds position feedback back to the drive over the DRIVE-CLiQ plug; the M17 power connector on the same housing carries the motor cables, so the field-side wiring terminates at one M17 pair on the motor and no separate resolver or encoder cable gland is needed.
Mechanical envelope and degree of protection
Cylindrical shaft D14 × 30 mm suits a standard servo coupling or gearbox input, and the IP64 rating seals the motor body against dust and splashing water — adequate for inside-cabinet or sheltered machine-frame mounting, but not an open washdown zone. Packaging footprint is 452 × 250 × 267 mm for the single-piece shipper; the motor ships as one unit per order and falls under product class C (made to order, non-returnable) so the frame size and winding are confirmed at order entry rather than pulled from shelf stock.
Compliance and lifecycle status
RoHS compliance has been in force since 01-07-06 and REACH Art. 33 duty-toinform applies; export control is AL:N / ECCN:N_CNDU, which means the part ships without an export licence gate on the standard industrial-automation channel.
Sourcing posture for the BOM line
Because the 1FK2104-4AF00-2SB0 is product class C — manufactured to order rather than pulled from finished-goods inventory — sourcing goes through the RFQ channel against the specified quantity and lead time is confirmed at quote rather than off a stock shelf.
