The Siemens 1FK7042-5AK71-1KH0 sits on the 1FK7 compact synchronous servo line, a brushless AC servo sized for high-dynamic positioning axes where the drive electronics (SINAMICS S120, SIMOTION) close the loop over the connected encoder.
Independent industrial-automation channels carry it against BOM-level RFQs; volume pricing and current availability are confirmed at quote time, with no factory-direct line behind the code.
Not as a straight swap — both are 1FK7 compact frames but the suffix codes (1AK71-1KH0 vs 1AF71-1DB0) carry different shaft-stack, encoder and brake options, so the drive-side parameter set and the mechanical face must be reverified before commissioning.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
