Shaft height is 30 mm and feedback is the AM21-bit absolute encoder delivered through a hybrid connector, so a single cable carries power and feedback back to the S200 — the connector choice matters more for cabinet routing than the motor itself, and the absence of an oil seal plus IP54 sealing sets this as an indoor cabinet-adjacent axis rather than a washdown or outdoor station (cites:). ## Shaft-key mount, N tolerance, no holding brake The output side uses a shaft key with tolerance N and ships without a holding brake — for any vertical axis where back-driven motion is a safety concern the brake has to come from the mechanics or a different motor variant, and the N tolerance class on the keyed shaft dictates the fit of the coupling or pinion pressed onto it (cites:). Packaging is a single-piece shipper at 315.00 x 182.00 x 172.00 mm — the boxed footprint is what the receiving dock plans for, not the motor's installed footprint inside the machine, so the receiving pallet opening needs to clear that envelope (cites:,). ## Production status and compliance trail Lifecycle status reads active under the R220 group code, and the product is classed as built-to-order with no return-for-credit path — that means the BOM line is a committed order once it drops, not a stocked shelf item you can return against credit if the design pivots (cites:,).","metaTitle":"Siemens 1FL2103-4AF00-1MC0 Servo Motor, 0.4 kW, 1.27 Nm","metaDescription":"Siemens 1FL2103-4AF00-1MC0 SIMOTICS S-1FL2 servo, 400 V 3AC, 0.4 kW, 1.27 Nm, IP54, for SINAMICS S200.
