2.4 Nm holding-brake servo for the SINAMICS S210 line
The 1FK2104-5AF10-2SA0 is a SIMOTICS S-1FK2 HD servomotor with a 2.4 Nm stall torque and a holding brake, designed to drop onto the SINAMICS S210 drive platform through its native OCC interface. Two voltage bands are published on the nameplate: 0.75 kW at 3000 rpm from a 380–480 V supply, and 0.375 kW at 1500 rpm from a 200–240 V supply — so the same motor can be specified at 230 V or 400/480 V class cabinets without rewiring. Position feedback is an absolute single-turn 22-bit encoder (AS22DQC) and the cable exits through a rotatable M17 plug, which lets the wireman clock the connector to the cabinet routing rather than spin the motor in its flange. The shaft is a cylindrical D14 × 30 mm stub — no keyway — and the housing carries IP64, meaning the body tolerates dust and splash but is not a sealed washdown unit.
Lifecycle status and class-C build-to-order terms
The part carries 'current' and productStatus 'Active', so it remains in normal Siemens production at the time of the record — no last-time-buy window is flagged on this order code. RoHS compliance is declared from 01-07-06 and REACH Article 33 information is published for the part, which covers the substance-restriction declarations buyers typically need at goods-in.
Ordering codes and packaging context
Group Code R220 and Product Group 9021 are the internal Siemens ordering identifiers on this line; the part ships one piece per package at 452 × 250 × 267 mm carton dimensions. Export control is AL:N / ECCN:N_CNDU — no special licence is triggered for cross-border movement of this motor under the declared classification.
