On the 380-480 V bus it delivers PN of 1.07 kW at a rated speed nN of 6000 rpm; on the lower 200-240 V bus the same frame drops to PN of 0.75 kW at 3000 rpm — so the drive selection (or the existing line transformer) decides which of the two ratings is the working point, not the motor itself. The shaft is D19x40 with a feather key, the feedback is a 22-bit single-turn absolute encoder (AS22DQC), and both the signal side (DRIVE-CLiQ M17 plug) and the power side (M17 power connector) are M17-coded — meaning the motor cables are keyed to the family, not the user. ## IP64 rating and where the motor physically lives With an IP64 degree of protection, the 1FK2104-5AK00-1SB0 is sealed against dust ingress and splashing water but is not rated for washdown or high-pressure cleaning — it is intended for the inside of a cabinet or a shielded machine zone, not a food-and-bev line or an outdoor pedestal. The DRIVE-CLiQ M17 interface is what auto-negotiates the encoder type, motor parameters and temperature model with the SINAMICS S120 at first connect; the 22-bit single-turn resolution gives 4,194,304 steps per mechanical turn, which is the resolution ceiling for position loops run from this motor without adding an external measuring system. ## Lifecycle status, compliance trail, and what 'product class C' means at the RFQ desk Siemens lists the 1FK2104-5AK00-1SB0 as Active, with RoHS compliance dating from 01-07-06 and REACH Article 33 disclosure obligations carried through the supply chain; export classification is AL:N / ECCN:N_CNDU, so it ships under standard commercial paperwork with no dual-use license gate. Sourcing this part is therefore a confirm-the-spec-and-commit conversation, not a returnable-shelf pickup: the motor is wound, encoder-aligned and shaft-machined for the order, which is also why the packaging is sized for a single piece (452 x 250 x 267 mm) and the quantity unit is 1. The internal Group Code is R220 and Product Group 9021 — the same Siemens classification a parts planner uses to land the right motor when reordering across multiple 1FK2 frame sizes. ## Sourcing posture for this build-to-order servo With product class C and the part confirmed Active, the procurement move is a quoted-to-order ask against the BOM line rather than a spot buy: the motor is configured, wound and serialized for the order, and price is confirmed against quantity and bus-voltage variant at RFQ time — not a stock-holding line item.","metaTitle":"Siemens 1FK2104-5AK00-1SB0 SIMOTICS S-1FK2 HD Servo, 2.4 Nm","metaDescription":"Siemens 1FK2104-5AK00-1SB0 SIMOTICS S-1FK2 HD servo motor, M0=2.4 Nm, PN=1.07 kW at 6000 rpm (380-480 V); DRIVE-CLiQ and absolute encoder.
