The motor is listed under the Servo Motors category, filed at the path Servo Motors within the broader Motors & Motor Controls catalog, which is the typical placement for an axis-motor slot inside a machine control panel rather than a stand-alone line-drive (cite E*:,). ## Sourcing posture for an eol_hot servo motor Buyers specifying this motor onto a new line should plan for a formal cross-reference check before committing the BOM slot, because an eol_hot part does not offer the long-tail support a greenfield machine tool builder usually wants (cite E*:).","metaTitle":"1FK7042-5AF21-1PB0 Siemens Servo Motor, 5.44 kg, EOL hot","metaDescription":"Siemens 1FK7 compact synchronous servo motor, 5.44 kg, lifecycle flagged EOL hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF21-1PB0","Part #":"1FK7042-5AF21-1PB0","Weight":"5.44 kgs","Category":"Motors","description":"1FK7042-5AF21-1PB0 - 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":"$2,643.95","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I get pricing and availability for 1FK7042-5AF21-1PB0?","answer":"Pricing and availability are quoted against the RFQ through independent distribution for this eol_hot servo motor; the lead-time and quantity depend on the lot available at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AF21-1PB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK7042-5AF21-1PB0 when reusing this data.
