Mechanical build is a 45 mm shaft height, keyed shaft (tolerance N) with an axial connector exit and an integrated holding brake, sealed to IP65 with an oil seal at the shaft entry — the brake and the IP65 oil seal together let the motor hold a vertical axis at rest and survive the oil-mist and coolant splash of a machine-tool or transfer-line cabinet without a separate shaft seal. ## Driveline pairing and encoder feedback The part ships with the 21-bit angular connector (AS21) encoder, which is the feedback package that the SINAMICS S200 expects — going to a different encoder variant on the same motor family means re-validating the drive's auto-commissioning, so for a service swap you want this -1SB0 suffix on the replacement rather than a -1SA_ sibling. Siemens rates the unit as Group Code R220 / Product Group X0DM and product class C (made to order, non-returnable), so a line-down request has to be quoted against a confirmed BOM quantity — stock-and-go spares are not the supply model for this code. ## Compliance, export, and packaging footprint RoHS compliance has been in force since 01-01-18, and REACH Art. 33 duty-to-inform applies per the current candidate list — the documentation an audit or tender usually asks for is already on the Siemens record, which matters when a machine builder has to ship into EU jurisdictions. Export classification is AL:N / ECCN:N, so the part is not controlled under the standard dual-use lists and does not require an export licence for the usual destination set; a single unit ships in a 382 x 222 x 240 mm pack, one piece per orderable quantity. ## Active status, no successor on record Pricing and availability are confirmed at quote time against an RFQ: the make-to-order class C designation means lead time is governed by Siemens' configured production slot rather than shelf stock, so a tender or panel-build window should lock the order code and quantity before the production schedule freezes.","metaTitle":"Siemens 1FL2304-2AF11-1SB0 Servo Motor, 0.4kW, 400V 3AC","metaDescription":"Siemens 1FL2304-2AF11-1SB0 SIMOTICS S-1FL2 servo, 0.4 kW, 400 V 3AC, 3000 rpm, IP65 with brake, for SINAMICS S200.
