It belongs to the 1FL6 family that pairs natively with the SINAMICS V70 and V90 drive platforms, so wiring, encoder feedback, and commissioning macros stay inside that ecosystem — the motor side is designed to plug in without a third-party cable harness. ## Shaft, feedback, brake, and sealing Shaft height is 45 mm with a feather key and tolerance N, terminated through an angle plug — the right-angle connector keeps the cable bend radius predictable inside tight machine frames. Feedback is a 20-bit absolute encoder with 12-bit multi-turn, so the drive retains absolute position through power cycles — useful for machines that home once and never re-reference on every restart. An integrated holding brake is fitted, and the housing carries IP65 with the sealing ring in place — meaning the motor body tolerates typical plant-side coolant splash and dust ingress when the cable gland and shaft seal are correctly seated. ## Lifecycle read: NRND, not yet discontinued Existing spare-part and running-series demand is still served, but new machine designs are steered to the current-generation alternative; the part is not flagged as discontinued and no official LTB date appears on this record. Because it is built to order in product class C (manufactured per order, non-returnable), supply is confirmed against each request — no standing stock pool on the manufacturer side, which is normal for this configuration. ## Compliance and packaging notes RoHS substance compliance has been in effect since 01-01-18, and the REACH Article 33 candidate-list obligation is discharged through the standard Reach Information notice — the documentation a buyer expects for shipment into the EU/EEA. Shipping carton is 432 x 222 x 250 mm for a single-piece quantity unit.","metaTitle":"Siemens 1FL6042-1AF61-2LB1 Servo Motor, 0.4 kW, 3000 rpm","metaDescription":"SIMOTICS S-1FL6 servo, 3AC 400 V, Pn=0.4 kW, Nn=3000 rpm, M0=1.9 Nm, with brake and 20-bit absolute encoder, IP65.
