The shaft is D19 x 40 mm with a feather key, the absolute encoder is a single-turn 22-bit AS22DQC, and the housing carries IP65 protection — meaning the motor tolerates dust ingress and low-pressure water jets, so it can sit on a machine skid near coolant splash without an additional shroud, but it is not sealed for full washdown immersion. ## Two speed points, one motor Siemens rates this motor at 0.75 kW PN at nN = 3000 rpm on a 380-480 V drive bus, and again at 0.375 kW PN at nN = 1500 rpm on a 200-240 V bus — so the same frame number is used in both 400 V-class European panels and 230 V-class North American builds without a re-spec, which matters when the BOM line is shared across regions. The holding brake keeps the axis parked when the drive is de-energised; the DRIVE-CLiQ M17 plug carries the encoder and electronic nameplate to the SINAMICS S120 line, so commissioning swaps the motor against the connected drive's automatic parameter read rather than a manual entry. ## Bookkeeping and compliance trail Siemens classifies this under Group Code R220 and Product Group 9021, ships it as a single-piece unit (quantity unit 1 Piece, packaging 452.00 x 250.00 x 267.00 mm), and lists Product class C — meaning it is built to order and cannot be returned against credit once the order is in production. Compliance: the motor has been RoHS-conformant since 01-07-06, falls under REACH Art. 33 information duty (current SVHC list applies), and is not export-controlled — AL: N / ECCN: N_CNDU — so cross-border shipments do not require a licence declaration for this code.","metaTitle":"Siemens 1FK2104-5AF11-1SB0 servo motor, 0.75 kW, IP65, brake","metaDescription":"Siemens SIMOTICS S-1FK2 HD servo motor, 2.4 Nm, 0.75 kW at 3000 rpm (380-480 V), with holding brake, IP65, DRIVE-CLiQ M17.
