The 1FK2104-5AK11-1SA0: The SIMOTICS S-1FK2 HD servo motor on this code delivers a stall torque M0 of 2.4 Nm with a rated power of 1.07 kW at nN=6000 rpm on the 380-480 V class, and the lower-voltage 200-240 V rating settles to PN = 0.75 kW at nN=3000 rpm — the bus voltage you feed the SINAMICS S210 determines which curve you actually sit on. Absolute encoder single-turn 22-bit (AS22DQC) on the rear, paired with the OCC interface and a rotatable M17 plug — the connector orientation matters at panel build because a fixed-exit cable would force the cabinet layout to bend around it. Holding brake ships fitted from the factory and the shaft is D19x40 mm with feather key, so the mechanical side of the swap-out is defined: the driven element must accept a 19 mm keyed journal at 40 mm length.
Sealing, duty envelope, and what IP65 actually buys you
IP65 on the motor body means the housing resists dust and water jets from any direction, so the unit survives washdown on a converter-equipped machine tool or a conveyor line near coolant splash — the sealing assumption is mated connector fitted, not a bare shaft. Operating envelope is the two voltage rails already noted (380-480 V and 200-240 V); the encoder resolution and brake integration come from the factory, so the commissioning job is parameter download into the S210 and mechanical alignment, not field wiring of feedback.
Lifecycle, ordering class, and documentation pack
Lifecycle stage reads current, and the product class is C — built to order, non-returnable, non-reusable — so this motor is sourced per BOM line and quoted against the order quantity; surplus speculation does not apply on a made-to-order code. Compliance on file: RoHS conformity since 01-07-06 and REACH Art. 33 duty-to-inform per the current candidate list, with export control classification AL:N / ECCN:N_CNDU — the declaration pack is what a quality or shipping desk asks for first. Group Code R220, Product Group 9021 — the Siemens internal codes that line up with the SIMOTICS S-1FK2 HD family on the SINAMICS S210 axis; packaging is 1 piece at 452 x 250 x 267 mm shipping carton.
