Headline torque, speed and encoder combo
The 1FK2104-5AK11-0SB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 servomotor family for SINAMICS S120, carrying M0 = 2.4 Nm of standstill torque and PN = 1.07 kW at nN = 6000 rpm on a 380–480 V supply, or PN = 0.75 kW at nN = 3000 rpm on a 200–240 V supply. It ships with a holding brake, an IP65 housing, a cylindrical D19 x 40 mm shaft, a single-turn 22-bit absolute encoder (AS22DQC), a DRIVE-CLiQ plug M17, and an M17 power connector — the standard 1FK2 high-dynamic connector complement. In field terms, 2.4 Nm standstill and 1.07 kW on the 6000 rpm winding puts this frame in the medium-inertia, high-dynamic slice of the 1FK2 line, sized for the kind of cyclic acceleration/dwell duty a converter-fed indexing axis or a small-format packaging head demands — provided that the drive line on the SINAMICS S120 is configured for the 1FK2 HD motor data set rather than the older 1FK7 firmware blocks.
Mechanical and connector integration
The shaft is the cylindrical D19 x 40 mm variant (no key) and the housing carries IP65 — meaning the body is sealed against jet water and dust ingress, so the motor can sit near process washdown or outdoor cabinet faces provided the cable glands and the DRIVE-CLiQ/power side are dressed to the same rating. The encoder is read out through the M17 DRIVE-CLiQ plug, and the power side terminates through a size M17 connector — no separate incremental cable to route. Unit packaging is 452.00 x 250.00 x 267.00 mm for a single piece, which is the box outline the MRO planner should allow for when budgeting shelf or staging space ahead of a turnaround window.
Lifecycle and group-code status
Export control markings are AL: N / ECCN: N_CNDU — no special export licence applies on the part code itself, but the shipping destination still drives the standard commercial-export paperwork.
Substance compliance on record
RoHS substance-restriction compliance has been declared since 01-07-06, and the part carries the Reach Article 33 duty-to-inform statement per the current candidate list. No UL/IEC third-party certificate is recorded in the available spec set, so any certification claim beyond the RoHS/REACH entries above would need to be confirmed against the manufacturer's declaration pack at quote time.
Sourcing posture
Because the product class is built-to-order and the line remains active, the realistic procurement path is quoted-to-order against the BOM line — quantity, lead time, and any project-specific declaration pack are confirmed at RFQ.
