The 40 mm shaft height positions it as the small-frame member of the 1FL2 family. Mechanical package reads for panel-level integration: hybrid connector AM21bit, keyed shaft with N tolerance, holding brake, and IP65 sealing with oil-resisting seal — a build suited to factory automation cells where occasional lubricant mist reaches the housing, not to food-grade washdown or outdoor cabinets. ## Fit to SINAMICS S200 and commissioning posture The description block pairs this motor explicitly with the SINAMICS S200 drive — the drive performs the auto-identification on first power-up, recognises the 21-bit AM21bit encoder, and resolves the holding-brake control timing from the motor's electronic rating plate. Substitute the motor only within the same 1FL2 family; controller parameter sets for neighbouring families do not migrate cleanly across encoder and brake-wiring variants. Holding brake and IP65-with-oil sealing are factory-fit options — the order code suffix encodes both, so a swap on the line cannot drop a non-brake motor into a brake-expecting application without a parameter change in the drive's safety configuration. ## Lifecycle and compliance state Compliance posture: RoHS substance restrictions have applied since 01-01-18, and the part is subject to REACH Art. 33 duty-to-inform per the current candidate list — the declaration pack is requested alongside any quote.","metaTitle":"Siemens 1FL2104-4BG11-1MC0 Servo Motor, 1 kW, 3000 rpm","metaDescription":"Siemens 1FL2104-4BG11-1MC0 SIMOTICS S-1FL2 servo, 1 kW, 3000 rpm, IP65 with oil, holding brake.
