Quotations on EOL/hot stock are confirmed at RFQ through independent distribution; availability is lot-specific and pricing reflects the remaining channel inventory. ## Handling and panel-side notes for a 4.54 kg servo The lead dressing on a 1FK7 motor is short and angled; when pulling the unit for swap, support the cable harness so the drag does not kink the insulation at the connector strain relief — that kink is the most common field-reject cause on a like-for-like replacement.","metaTitle":"Siemens 1FK7042-5AK71-1UG3 Servo Motor, EOL, 4.54 kg","metaDescription":"Siemens 1FK7042-5AK71-1UG3 servo motor, listed at 4.54 kg, flagged EOL/hot — sourced to order against an RFQ through independent distribution.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AK71-1UG3","Part #":"1FK7042-5AK71-1UG3","Weight":"4.54 kgs","Category":"Motors","description":"1FK7042-5AK71-1UG3 - SERVO MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,588.39","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies 1FK7042-5AK71-1UG3 and how is it quoted for volume purchases?","answer":"Supply runs through independent industrial-automation distribution rather than the OEM's new-order channel, given the eol_hot lifecycle flag.
