Technical datasheet for the SICK-STEGMANN TTK70 absolute, non-contact linear measuring system for linear motors, featuring HIPERFACE interface and RS-485…
The TTK70 is an absolute, non-contact linear measuring system designed for linear motors. It consists of a reading head and a magnetic tape with a twin-track code containing both incremental and absolute tracks. The system calculates absolute position values without requiring a reference run and transmits data via the HIPERFACE interface while providing incremental sine/cosine signals.
