Card image — what lands on the bench
The 1FK2104-5AK11-0MA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family sized for SINAMICS S210 drives, holding a static torque M0=2.4 Nm with an integrated holding brake and shipping in a 452.00 x 250.00 x 267.00 mm pack — a compact high-dynamics frame aimed at small-format motion axes rather than heavy industrial loads. Siemens rates the unit for two operating windows: PN=1.07 kW at nN=6000 rpm on a 380-480 V supply and PN=0.75 kW at nN=3000 rpm on a 200-240 V supply, so a single motor code covers both the European 400 V class and the North American 230 V class without re-specifying the winding.
Mechanical and feedback envelope
The shaft is a plain cylindrical D19x40 mm, which dictates the coupling selection and the radial load budget at the driven end — gear or belt drive stages must be sized against that 19 mm journal rather than a generic NEMA or metric-equivalent frame. Feedback is an AM22DQC absolute encoder, 22-bit single-turn plus 12-bit multi-turn resolution — the multi-turn range means the drive retains absolute position over power-cycle events without an external battery module, a key fit decision for suspended or vertical axes where re-homing on every power-up is unacceptable. The motor carries an IP65 degree of protection with an M17 rotatable plug on the OCC interface — IP65 tolerates dust and low-pressure water jets, so the unit is appropriate for cabinet-through-mount installations near coolant splash or food-and-bev washdown zones provided the mating cable gland is sealed to the same class; the connector orientation can be rotated on install to suit the cable exit direction.
Lifecycle, compliance, and kit integrity
Lifecycle status is recorded as current and product status as Active, with the field also marked current — the motor remains in normal production and is sourced as a built-to-order Class C item (manufactured to order, not returnable for credit), so the BOM line should be planned against the configured lead time rather than off-the-shelf shelf stock. Substance compliance covers RoHS directive conformity since 01-07-06 and REACH Article 33 information duty per the current candidate list — the motor can be specified into EU-market equipment without additional substance-declaration paperwork beyond the standard Siemens Reach Information set; export control regulations read AL:N / ECCN:N_CNDU, indicating no special export licence is triggered for typical destinations. The kit ships under Product Group 9021 / Group Code R220, one piece per Quantity Unit, one piece per Packaging Quantity — the carton is the single shipper and no accessory pack (separate brake connector, mating connector, or encoder cable) is documented inside this order code, so any add-on cable or mating connector must be confirmed against the BOM line before the technician is dispatched.
Spec the BOM and get the quote
For a procurement line targeting this code, the relevant confirmed fit points are: SINAMICS S210 family pairing, 2.4 Nm static torque, dual-voltage rating (1.07 kW at 6000 rpm on 380-480 V or 0.75 kW at 3000 rpm on 200-240 V), AM22DQC absolute encoder, IP65 housing, M17 rotatable plug, integrated holding brake — quoting against this BOM line confirms the configured motor is the one being built rather than a generic substitute.
