It carries 1.27 Nm of static stall torque (M0) and 0.4 kW rated power at 3000 rpm on a 380–480 V bus, dropping to 0.2 kW at 1500 rpm on a 200–240 V bus — the same frame, two operating points, which is how Siemens sizes a single motor for both 230 V and 400 V class cabinets without respinning the mechanics. ## Ratings read for fit, not just on paper IP65 on the housing means the body tolerates directed water jets and dust ingress — fine for a cabinet-side mounting or a food-adjacent packaging line, but it does NOT cover the connector face when unmated; the DRIVE-CLiQ M17 and power M17 plugs need their sealing caps or the cordset fitted before washdown. The D19×40 mm shaft with feather key is the standard 1FK2 low-flange format — the keyway lets a gearbox or coupling transmit peak acceleration torque without slip, but it also raises the balance grade requirement on the driven side, so spec a keyway-balanced coupling rather than a set-screw collar if the cycle runs past 3000 rpm. Absolute encoder AM22DQC (22-bit singleturn + 12-bit multiturn) returns the absolute shaft position on power-up — no homing move required after a controller restart, which closes the cycle budget by the time a reference search would otherwise consume, and lets the SINAMICS S120 hand off position to a robot controller the instant the bus comes up. DRIVE-CLiQ is the proprietary Siemens motor-to-drive digital link, so the motor only talks natively to a SINAMICS S120 control unit — a third-party drive would need the equivalent SIZER-configured SINAMICS or a third-party feedback card that accepts the AM22DQC signal level; otherwise the motor and drive stay in their own walled garden. ## Compliance and documentation posture RoHS compliance is declared since 01-07-06, well before the motor's date of manufacture, and the supplier is on the hook for REACH Article 33 candidate-list disclosure if any substance in the motor crosses the threshold — buyers exporting into the EU should expect the standard Reach Information sheet on request. Export control sits at AL:N / ECCN:N_CNDU — no special license required for shipment outside the US, which keeps the cross-border paperwork light for a European-built servo. Product class C flags this as a built-to-order motor: configuration is frozen once the order enters production, and the unit cannot be returned for credit — confirming the encoder variant, shaft format, and connector orientation at the quote stage is non-negotiable because swapping a non-stock motor mid-build eats the lead-time budget. ## Sourcing posture for an active made-to-order motor Pricing and availability for 1FK2104-4AF01-1MB0 are confirmed against the order quantity at quote time through independent distribution; lead time and any volume breaks are returned in the same response, with factory trace and warranty backing carried through.","metaTitle":"Siemens 1FK2104-4AF01-1MB0 servo motor, 1.27 Nm, 0.4 kW","metaDescription":"Siemens 1FK2104-4AF01-1MB0 SIMOTICS S-1FK2 HD servo motor, 1.27 Nm stall, 0.4 kW at 380–480 V.
