A 21-bit hybrid encoder (AM21bit) closes the position loop with the resolution needed for sub-degree indexing on packaging, pick-and-place, and small-format CNC auxiliaries — the resolver-free commutation lets the drive autotune without hall sensors at first commissioning. Shaft height is 40 mm with a keyed shaft, tolerance N, and no holding brake — the holding-brake option is a different order-code variant, so confirm the brake position on the BOM line before specifying this MPN in a vertical-axis application. ## Protection class and cabinet fit IP54 is achieved without an oil seal, so the shaft entry is splash-protected but not pressure-wash rated — the motor is sized for an enclosure or a sheltered machine interior, not for a washdown food-line environment or an outdoor mounting where IP65 or higher is the baseline. The hybrid connector AM21/AM21bit carries power and encoder in one plug, so the cabinet-side cable routing is a single assembly per axis — that simplifies the panel build but ties the encoder protocol to the cable, and field replacement requires the matching Siemens hybrid lead set, not a generic M23. ## Lifecycle and sourcing posture Lifecycle stage is current and the product is listed as Active — it is a build-to-order code in product class C (made to order, non-returnable), so each unit ships against a confirmed PO rather than from shelf stock, and lead time is confirmed at the quote stage, not at the catalog. RoHS compliance is in effect since 01-01-18 and REACH Art. 33 candidate-list information is published — both are required for EU ship-out, and the declarations accompany the shipment on request. ## Quoting this code against your BOM Order code 1FL2104-4AF00-1MC0 is supplied through independent distribution and quoted against the BOM line on RFQ — pricing and current availability are confirmed at quote time, and the same code is matched against the SINAMICS S200 firmware slot on the drive side before the order is committed.","metaTitle":"Siemens 1FL2104-4AF00-1MC0 Servo Motor, 1 kW, 400V","metaDescription":"Siemens 1FL2104-4AF00-1MC0 SIMOTICS 1FL2 servomotor, 1 kW, 400V 3AC, 3000 rpm, for SINAMICS S200.
