It carries a 40 mm shaft height, a keyed shaft with N tolerance, a holding brake, and a hybrid AM21bit connector — the matching drive is the SINAMICS S200, so the motor ships configured for that drive's electronic nameplate and one-cable hybrid feedback topology rather than as a standalone servo. ## Sealing, brake, and the SINAMICS S200 pairing IP65 with oil seal means the shaft seal is the wet-end barrier, not the housing — installation in a food-and-beverage or machine-tool environment where cutting fluid or washdown reaches the shaft area is acceptable, but the seal lip should be inspected on a held-spindle downtime window because the oil seal is the consumable. The holding brake is integral rather than retrofitted, which keeps the brake-coil wiring inside the same hybrid connector and removes a separate cable run — a practical advantage when retrofitting into older machines where the original servo slot has limited cable routing. ## Lifecycle and catalog classification Catalog flags worth flagging to procurement: Product class C indicates the unit is made to order and cannot be returned for credit, so the BOM line should be sized to the actual build quantity rather than booked against a returnable stock buffer. Logistics footprint is a single-piece pack at 382 x 222 x 240 mm — useful for receiving-bench planning rather than cell-level selection.","metaTitle":"Siemens 1FL2104-4AF11-1MC0 Servo Motor, 1 kW, 3.2 Nm","metaDescription":"Siemens 1FL2104-4AF11-1MC0 SIMOTICS S-1FL2 servo, 1 kW at 3000 rpm, 400 V 3AC, IP65 with holding brake, for SINAMICS S200.
