Paired drive and rating envelope
The 1FL2102-2AF10-0HC0 sits inside the SIMOTICS S-1FL2 family built to match the SINAMICS S200 drive — the 400 V 3AC supply, hybrid AS17-bit encoder, and 20 mm shaft height line up to a low-voltage S200 axis, so the motor is sized for point-to-point positioning or small-format rotary axes on packaging, labeling, or small-format assembly machines rather than a heavy feed drive. Rated 50 W continuous with a 0.16 Nm stall and rated torque (M0 = Mn = 0.16 Nm) and a nominal speed of 3000 rpm, the motor lands in the low-inertia 1FL2 bracket — useful where the drive must accelerate a small load quickly, but not where the axis needs sustained high torque. IP54 with the holding brake option fitted protects against dust ingress and light splash, so cabinet-internal mounting behind sealed cable entry is the realistic deployment rather than direct washdown exposure.
Shaft, encoder, brake — what the build includes
Plain shaft with tolerance N (no keyway) and a hybrid connector carrying the AS17-bit absolute encoder — the connector standardises wiring against the S200 drive harness, which keeps commissioning to a single cable family on the S200 side. The holding brake is included, which matters for vertical or gravity-loaded axes where the motor must hold position with the drive powered down; on a horizontal small-format axis it is a useful redundancy rather than a load-bearing function. Shaft height 20 mm is the short-frame end of the 1FL2 range; the 0.16 Nm continuous figure should be derated against the customer's mounting and ambient rather than the headline figure, since IP54 without an oil seal implies standard sealing rather than harsh-duty sealing. For fit decisions the buyer should confirm the matching S200 drive firmware slot for AS17-bit encoders and the hybrid connector pinout before locking the BOM line.
Lifecycle status and product class
Siemens lists the part under product class C — manufactured to order, non-returnable, non-reusable against credit — which is the typical posture for a configured servo with a specific shaft, brake, and connector combination. Lifecycle status is recorded as current/active, so this is not a discontinued stock buy; it is a configured order placed against the manufacturer's production line. For MRO purposes that means the maintenance spare is the same order code rather than a drop-in replacement; the lifecycle event to watch is a future PCN or LTB against the 1FL2 family, not a derivative already published.
