Form factor and what lands on the bench
The 1FK2104-5AK10-1MB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family built to drop into a SINAMICS S120 drive line, supplied as a single piece in its shipping box (452 x 250 x 267 mm) so the integrator unboxes a complete drive-end assembly rather than a kit. It carries a holding brake, an IP64 sealing class, a D19x40 mm shaft with feather key, the AM22DQC 22-bit + 12-bit multiturn absolute encoder, and both the DRIVE-CLiQ feedback plug and the power connector as M17 size — meaning the comms cable, the power lead, and the brake lead all share the same M17 form factor on the motor housing.
Ratings that drive the BOM fit
Rated output is 1.07 kW at nN = 6000 rpm on a 380-480 V bus, with a secondary rating of 0.75 kW at nN = 3000 rpm on a 200-240 V bus; the standstill torque figure is M0 = 2.4 Nm, so the motor pulls its rated load at low speed without leaving the constant-torque region on the SINAMICS S120 torque envelope. IP64 means the housing resists splashed water and dust ingress — fine for an enclosure-mounted machine but not a washdown bay, so a food-grade or outdoor deployment should look at the higher-rated sibling rather than expect this motor to survive direct hose-down.
Lifecycle posture and how to source it
Lifecycle status reads current and the product is ordered under class C — built to the buyer's configuration rather than stocked as a generic SKU — so the procurement path is a quote against the BOM with the exact encoder, brake, and connector options locked in before manufacture.
