Heidenhain Encoders Useful for Higher Shaft Speeds

Heidenhain Corporation has announced the start of series production of their ROC 2000 and ROC 7000, a new family of Absolute Solid Shafted Angle Encoders. Using the same mechanical connections and “footprint” as their incremental cousins (the ROD series), and the same scanning principles as their hollow shafted siblings (the RCN series). These new angle encoders feature an absolute track with serial code structure and an incremental track that is scanned by means of robust, single field scanning… so there is no need for a homing routine at power-up. These ROC angle encoders with integral bearing and solid shaft are especially useful for applications that require higher shaft speeds or larger mounting tolerances. A separate rotor coupling is used for coupling the shaft. This makes it possible to realize axial tolerances of up to ±1 mm depending on the rotor coupling used. The rotor couplings are capable of compensating for axial motion and misalignment between the encoder shaft and the measured shaft. These new ROC angle encoders are useful for both new applications or for an upgrade of an existing installation to absolute technology.
