HEIDENHAIN Product Solutions
HEIDENHAIN linear encoders measure the position of linear axes without intervening mechanical elements. This eliminates a series of potential error sources such as backlash, pitch error, or heating of the recirculating ball screw. Wherever rigorous position accuracy and high machining speeds are needed, linear encoders are essential.
Sealed linear encoders feature optimal protection from dust, chips, and splash water. They are especially ideal for use in manually operated machine tools and also in numerically controlled machine tools.
Exposed linear encoders have zero mechanical contact between the scanning head and scale or scale tape. Applications include pick-and-place machines and direct drive systems, production and measuring equipment in the semiconductor industry.
HEIDENHAIN angle encoders enable high-accuracy angular measurement down to a few arc seconds. Various design options offer the optimal solution for any application: sealed versions for high robustness, modular solutions for maximum flexibility in the application, and angle encoder modules with an integrated precision bearing. As a result, process reliability and positioning accuracy are always perfectly matched to the given scenario.
Thanks to their very high system accuracy, angle encoders with an integral bearing are ideal for demanding applications such as machine tools and printing machines.
Modular angle encoders can be perfectly matched to the application, offering a choice of optical or magnetic scanning and numerous combinations of circular scales, scale drums, and scanning heads.
The optimal interplay between angle encoder modules and their high-precision bearings results in high measurement and bearing accuracy, very high resolution, exceptional repeatability, and the added benefit of easy installation.
Rotary encoders from HEIDENHAIN stand for premium quality, durability, and precision, delivering accurate and dependable position and speed measurement. Due to their outstanding features and rugged, easy-to-install design, HEIDENHAIN rotary encoders have been used throughout the world for many years.
