Sizing this 50 W servo into a SINAMICS S200 cell
The Siemens 1FL2102-2AF01-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, rated for 400 V 3AC supply, 50 W rated power, 3000 rpm rated speed, with 0.16 Nm continuous stall and 0.16 Nm rated torque on a 20 mm shaft height — matched to the SINAMICS S200 drive platform. At this power level the motor sits in the very-low-inertia class: 0.16 Nm continuous torque over a wide speed range makes it a fit for high-acceleration point-to-point axes — small parts handlers, indexing tables, light-label and dispenser stations — rather than continuous-torque conveyors.
Feedback, brake, and shaft detail
Feedback is the AS17 bit absolute encoder (single-turn, 17-bit resolution) wired through a hybrid connector, so cable routing and connector spec must follow the SINAMICS S200 motion cable list — the hybrid cable carries power and feedback in one jacket. Shaft is keyed with tolerance N and there is no holding brake on this build. A keyed shaft needs a keyed coupling on the driven side; the absence of a brake means the axis must be back-drivable or rely on the drive's regenerative stop profile — vertical loads without a counterbalance are not a fit.
Sealing, environment, and what IP65 with oil seal covers
Protection class IP65 with oil seal — the seal is a wet-end barrier on the shaft entry, so the motor body tolerates light coolant splash and dust typical of light-assembly cells, but it is not rated for high-pressure washdown (IP67G/IP69K) or submerged duty.
Build-class and compliance paperwork for the contract buyer
Product class C — built-to-order, non-returnable, non-reusable. For a contract line this means each unit is produced against the order; substitution off the customer's AVL needs a written deviation, and returns against credit are not available on this build class. As a build-to-order part, lead time is set at quote against the RFQ and is confirmed per order quantity.
