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.","metaTitle":"Siemens 1FK2104-5AK11-0SB0 SIMOTICS S-1FK2 HD servo motor","metaDescription":"Siemens 1FK2104-5AK11-0SB0 SIMOTICS S-1FK2 HD servo motor with brake, 2.4 Nm, 1.07 kW at 6000 rpm.
