The motor, the drive it locks to, and the ratings that decide fit
The 1FL2102-2AG10-0SC0 is a SIMOTICS S-1FL2 low-voltage servo in the 1FL2 family, supplied as 200 V 3AC with a rated power of 50 W and a rated speed of 3000 rpm; both standstill torque M0 and rated torque Mn are 0.16 Nm, so this is a constant-torque-across-speed frame sized for low-inertia point-to-point motion rather than a high-inertia machine tool spindle (cites:). Shaft height is 20 mm with a plain shaft (tolerance N), a holding brake fitted, and a hybrid connector — meaning the power and feedback conductors share a single plug rather than separate connectors, which simplifies the cable run back to the drive (cites:). The matching drive line is SINAMICS S200, so a swap to a different servo amplifier family would require firmware-side setup changes even if the mechanical envelope matches (cites:,).
Protection class and sealing — what IP54 without oil seal actually permits
The body carries IP54 protection without an oil seal, which means dust ingress is limited and splashing water from any direction is tolerated, but full washdown or submerged-shaft service is not in scope — a panel-mount or cabinet-internal installation is the natural home for this frame (cites:). Plain shaft with tolerance N and no oil seal means the through-shaft side is not sealed against oil mist or coolant exposure; if the application is near a lubricated gearbox or a cutting-fluid zone, a separate splash guard or a sealed coupling should be considered in the BOM (cites:).
Lifecycle and ordering mechanics — active, class C, no cancellations
Lifecycle stage reads as current on this code, so production is active and the part is being built today — but the listed product class is C, which on a Siemens line means the unit is produced to order and cannot be returned, reused, or re-credited, so order quantities must match the actual build rather than be padded as buffer stock (cites:,). Commercial coding is Group Code R220, Product Group X0DJ, packaging quantity 1 piece per pack, and packaging dimensions 315.00 x 182.00 x 172.00 mm — the single-piece pack and the build-to-order class mean RFQs should be sized to the real BOM line, not to speculative inventory (cites:,).
