Feedback is the 21-bit absolute encoder on the angular connector variant, and the shaft configuration ships with a key and tolerance N; no holding brake is fitted on this code, which is the choice for axes where braking is handled externally or by the gearbox. Group code R220 / product group X0DK marks the motor into the SIMOTICS servo ordering line, and lifecycle status is recorded as Active. ## Ratings, encoder, and IP class The 2 kW power rating, 3000 rpm rated speed, and 8 Nm stall torque set the load envelope on the SINAMICS S200 axis; picking a motor in the same 1FL2 family but at a different rating changes the drive sizing, not the cable set, so this code is the drop-in for the 52 mm SH, 2 kW / 8 Nm position on a build sheet. IP65 with oil seal on a keyed shaft is the duty class for machine-side mounting where the motor sits close to gearbox lubricants or cutting fluid — the seal is what protects the bearings; the rating does not cover direct washdown, so the motor is placed inside the machine envelope, not in an exposed location. Compliance documentation traces to RoHS conformity since 01-01-18 and REACH Article 33 candidate-list information; the product class entry notes that this is a made-to-order configuration that cannot be reused or returned against credit. ## Sourcing posture for an Active build-to-order code Lifecycle is recorded as Active on the manufacturer line, and the product class is the build-to-order 'C' class — meaning each unit is configured and built per the order code rather than drawn from a finished-goods shelf, which is the contractual reality behind a quoted lead time on this motor. Group code R220 places the motor in the Siemens SIMOTICS S-1FL2 ordering family for SINAMICS S200, so the matching drive, cabling, and gearbox selection all key off the same family designation rather than a one-off code.","metaTitle":"Siemens 1FL2105-4AF01-1SB0 Servo Motor, 2 kW, 400 V 3AC","metaDescription":"Siemens SIMOTICS 1FL2 servo motor, 2 kW, 400 V 3AC, 3000 rpm, 8 Nm M0, 21-bit encoder, IP65 oil seal, for SINAMICS S200.
