It speaks DRIVE-CLiQ natively through the M17 plug on the motor, which is what makes the part 'meet it where it is' — replacement of an older 1FK2 on the same drive keeps the electronic nameplate, encoder resolution and safety wiring intact, so the cabinet-side harness does not have to be re-engineered. ## Encoder, shaft, and what sits behind the rating Feedback is an absolute encoder AM22DQC at 22-bit single-turn + 12-bit multi-turn, which is the resolution S120 expects for high-dynamic positioning — substituting a lower-bit encoder on this mechanical frame would limit the drive's loop performance. The shaft is cylindrical D19x40 mm and the housing carries IP65, meaning the motor tolerates typical industrial cabinet and machine-base environments with occasional splash and dust, but it is not a washdown-rated food-grade seal — confirm the deployment zone before specifying it on a wet line. The power connector is the same size M17 as the DRIVE-CLiQ signal connector; mismatching the two leads to a wrong-family cordset is the common retrofit trip-up, so the mating cable set must be matched to the M17 power/signal pair rather than reused from an M23-equipped predecessor. ## Lifecycle, ordering class, and the quoting reality Lifecycle stage reads 'current' and product status is Active on the record — the 1FK2104-4AF11-0MB0 is not on a phase-out path, so a retrofit BOM line built on this code is safe to commit against future production runs. Product class is 'C' — produced to order, non-returnable and not re-usable — which is the Siemens commercial classification for configured servo motors; this is why price and availability always come back against an RFQ rather than off a shelf price list. ## Packaging, export, and the physical handoff Supplied one piece per package with carton dimensions 452 x 250 x 267 mm — the 1FK2104-4AF11-0MB0 ships in a single-motor box, not a multi-pack, so receiving bay handling plans for one crate per line item rather than a bulk pallet.","metaTitle":"Siemens 1FK2104-4AF11-0MB0 SIMOTICS S-1FK2 servo, 0.4 kW","metaDescription":"Siemens 1FK2104-4AF11-0MB0 SIMOTICS S-1FK2 HD servo motor, 0.4 kW at 3000 rpm, with holding brake and DRIVE-CLiQ.
