It runs on a 400 V 3AC supply, so the motor lands on the standard three-phase industrial bus without a step-up transformer — the same bus that feeds most European-panel machinery and the SINAMICS S200 it is paired with. ## Mechanical fit for retrofit and new-build panels The shaft height is 52 mm, which sets the frame size within the 1FL2 family and defines the flange footprint a panel builder has to match on the gearbox or coupling side — drop-in replacement only works if the replacement motor shares that 52 mm shaft height. The variant carries a plain shaft with tolerance N (no keyway) and uses an angular connector at the cable entry, so the power and feedback cable leaves the motor body at a defined angle rather than axially — useful where the cabinet geometry forces a side exit. It does not include a holding brake, so any vertical-axis application that needs a fail-safe stop has to specify that function externally or pick the -braked sibling variant in the 1FL2 lineup. The encoder is 21-bit, which gives roughly 2 million counts per revolution — that resolution is the floor on positioning repeatability for a point-to-point move; a downstream indexing or cam profile application should confirm it meets the commanded increment before locking in the BOM. ## Environment, sealing, and the SINAMICS S200 pairing Protection class is IP65 with the oil seal fitted, meaning the motor body resists dust ingress and low-pressure water jets from any direction — that rating covers typical industrial cabinet and machine-base environments, but the sealing depends on the connector being mated and the cable gland seated, not just the housing. The motor is explicitly matched to the SINAMICS S200 drive, so the electronics side, parameter set, and cable are pre-validated as a system — the drive commissioning is the place to confirm the motor ID is loaded into the S200 project before the first move command. ## Lifecycle, compliance, and ordering posture Lifecycle stage is recorded as current, and the product is listed as class C — produced to order, non-returnable and non-reusable against credit — so the BOM position needs a forecast behind it; sourcing from independent channels is the way to back-fill urgent spares when the production schedule does not align with a line-down date. Export control is AL:N / ECCN:N, so no special export licence is triggered for routine cross-border shipments — relevant for a panel builder sourcing into North America from a European distributor or vice versa. Group code R220 and product group X0DK are the internal administrative identifiers on the line; the group code is the field the storeroom uses to bin the part, while X0DK is the commercial-line grouping used in the price list.","metaTitle":"Siemens 1FL2105-4AF01-0SB0 Servo Motor, 2 kW, 6.6 Nm","metaDescription":"Siemens 1FL2105-4AF01-0SB0 SIMOTICS 1FL2 servomotor, 400 V 3AC, 2 kW, 3000 rpm, 8 Nm / 6.6 Nm, IP65, paired with SINAMICS S200.
