S-1FL2 low-inertia servo, sized for the SINAMICS S200 slot
The Siemens 1FL2102-4AG01-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor rated at 200 V 3AC supply with a nominal output of 100 W at 3000 rpm and matched standstill / nominal torque of 0.32 Nm, in a shaft height 20 mm frame built to pair with the SINAMICS S200 drive family. The shaft key with tolerance N, hybrid connector AM21bit encoder interface, and 21-bit resolution make it the drop-in motor half for a S200PN / S200 basic axis where the small-frame S-1FL2 catalogue is specified — no holding brake is fitted on this code, which is the choice when the load cannot back-drive the motor on a power loss.
IP65 with oil seal — washdown-adjacent deployment envelope
IP65 with oil seal on the shaft exit defines the wet-side envelope: dust-tight and resistant to water jets, so the motor body survives food-and-beverage splash zones, machine-tool coolant rinse and the general factory ambient that would defeat an IP54 machine — but it is not an IP67 immersion-rated unit and should not be specified for submerged duty. The 315.00 x 182.00 x 172.00 mm shipping carton (single-piece pack) and 0.32 Nm frame mark this as a low-inertia point-of-motion axis — small-format conveyors, indexing tables, lab automation and the auxiliary feed axes on a S200-driven machine — rather than a main spindle or high-inertia load.
Order-made class, RoHS-aligned since 2018
Siemens classifies this motor under product class C — produced to order, non-returnable and non-reusable against credit — so the unit is built against the purchase order rather than pulled from bulk finished-goods stock; that drives the standard quoted-to-order lead-time posture on this code. RoHS compliance has been in force on this code since 01-01-18, and REACH Article 33 candidate-list disclosure applies via the Siemens Reach Information portal — buyers specifying into an EU or UK line can cite the dated RoHS line for the declaration pack without an additional concession request.
