What the 1FK2204-5AF01-0SB0 is and where it sits
The 1FK2204-5AF01-0SB0 is a SIMOTICS S-1FK2 CT servomotor from the 1FK2 family built to run on a SINAMICS S120 drive platform, with a standstill torque of 2.4 Nm and a rated output of 0.75 kW at 3000 rpm when supplied from a 380–480 V bus, or 0.375 kW at 1500 rpm from a 200–240 V bus, which means a single frame covers both the European 400 V class and the North American 230 V class without rewinding. Siemens lists this code as active and ships it as product class C — built to order against the received purchase order, not held as a returnable shelf item — so a confirmed BOM position with the SINAMICS S120 control slot, firmware slot, and motor module rating is required before the order can be released to the factory.
Shaft, feedback, and the cabling decision
The motor carries a cylindrical D19 × 40 mm shaft with an IP65 housing seal and an absolute single-turn 22-bit encoder (AS22DQC), which gives 4.19 million countable positions per turn — enough resolution for high-dynamic positioning without an external measuring system on the load side. Both the power lead and the DRIVE-CLiQ feedback cable terminate in M17 connectors, which keeps the encoder and power conductors on matched, keyed interfaces and removes the wiring-error path that bare terminal boxes open up during commissioning.
Compliance footprint and what the codes on the box mean
RoHS compliance has been in force for this code since 01-07-06, REACH Article 33 candidate-list information is published, and the export classification is AL:N / ECCN:N_CNDU — the latter flagging it as not controlled for dual-use export, which simplifies the cross-border paperwork on a replacement unit. The Siemens group code R220 and product group 9021 are the internal classification keys used to route the order inside the factory and to pull the correct test certificate and dimensional drawing — they are not approvals and should not be quoted as such on a customer-facing submittal.
Shipping carton and how it lands on the dock
The unit ships one per carton at 452.00 × 250.00 × 267.00 mm, which is sized for a single motor in its transit crate rather than a multi-up pack — a panel builder should plan the receiving bay around one-carton-at-a-time handling for the initial intake.
