The shaft-side mounting is IM B5 with the IM V1 and IM V3 variants also called out, and the power and signal connectors can be rotated through 270°, which lets the tech clock the connector face to the cabinet entry on install without re-terminating the cable. ## What eol_hot does to the BOM line For a kitting lead that means every spare pulled for the rack has to come with a confirmed source — the kit has to be complete with the mating connector set and the encoder cable, not a motor alone, because a stranded tech with a half-built spare is a two-hour round trip nobody budgets for.","metaTitle":"Siemens 1FK7042-5AK81-1TH3 Servo Motor, 3 Nm, 6000 rpm","metaDescription":"Siemens 1FK7042-5AK81-1TH3 1FK7 compact synchronous servomotor, 3.0 Nm, 6000 rpm, natural cooling, lifecycle eol_hot.
