HEIDENHAIN’s LC 195S and LC 495S encoders designed for functional safety.
Heidenhain introduced its absolute LC 195S and LC 495S sealed linear encoders that focus on the requirements for purely-serial absolute systems for Siemens SINAMICS drive components. The Functional-safety (FS) encoder versions are available for the EnDat 2.2 interface and now DRIVE-CLiQ interface, meaning they can be used as single-encoder systems in safety-related applications. In addition to safe processing of the position values, these encoders provide fault exclusions for the loosening of the mechanical coupling for various types of mounting. The resolution of the LC 195S and the LC 495S with an accuracy grade of 3 µm is 1 nm.
