The synchronous rotor design and integrated encoder feedback make it a closed-loop position actuator paired with a SINAMICS S120 or SIMOTION drive line. ## EOL status and what that means for replacement stock Lifecycle stage is recorded as eol_hot: the part is past its active manufacturing window and is sustained through remaining inventory and independent distribution rather than new factory runs. For a buyer filling a spare slot this is the cohort where lot-specific surplus and factory-traceable overhauls carry the line — quoted against an RFQ, no immediacy or volume claim made here.","metaTitle":"Siemens 1FK7042-5AF71-1DA0 Servo Motor, EOL","metaDescription":"Siemens 1FK7042-5AF71-1DA0 1FK7 compact synchronous servo motor, 4.54 kgs, EOL — sourced through independent channels against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1DA0","Part #":"1FK7042-5AF71-1DA0","Weight":"4.54 kgs","Category":"Motors","description":"1FK7042-5AF71-1DA0 - 1FK7 COMPACT SYNCHRONOUS MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,175.56","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1FK7042-5AF71-1DA0?","answer":"It is sourced to order through independent distribution on an RFQ basis — current pricing and available quantity are confirmed when the quote is raised against the BOM line."},{"question":"Will 1FK7042-5AF71-1DA0 drop into a panel that was specified around 1FK7042-5AF21-1UA0?","answer":"Both codes share the 4.54 kgs weight class and the 1FK7042 frame, so mechanical fit and rotor inertia line up.
