Shaft height, connector and what pairs to what
The Siemens 1FL2102-4AG00-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, built to run on the SINAMICS S200 servo drive system — the drive pairing is explicit on the model description and dictates the controller-side commissioning profile. Stator stack gives 100 W rated power at a nominal speed of 3000 rpm, with stall and continuous torque both listed at 0.32 Nm, so the motor delivers its full torque envelope from standstill up to base speed without a fan or forced-air assist. Mechanical side is shaft-height 20 mm with a keyed shaft and tolerance N, no holding brake, IP54 protection without an oil seal — the right build for a clean, dry cabinet location where ingress protection is moderate rather than washdown-grade. Feedback is a 21-bit absolute single-turn encoder wired out through a hybrid connector (power + signals in one shell), so the cabinet-side cable harness is the single-cable variety typical of the S-1FL2 family — fewer cores to land, one connector to key.
Lifecycle and the order classification that matters to procurement
Packaging is one piece per shipper with outer dimensions 315 x 182 x 172 mm and a non-controlled ECCN (AL:N / ECCN:N), so export paperwork for standard destinations is straightforward and no dual-use licensing is triggered. Compliance posture: RoHS-compliant since 01-01-18 and REACH Article 33 information available through the manufacturer's candidate-list portal — the environmental declarations a buyer needs for an EU shipment are on the record, not a request away.
Group and product codes inside the Siemens ordering system
Because the unit is built per order under product class C, the right commercial move is to specify quantity against the BOM and let the supplier confirm lead time at RFQ — holding stock of a made-to-order servomotor is not how this family ships.
