Heidenhain Expands Low-Priced Rotary Encoders Series and Increases Alternatives to Resolvers
SCHAUMBURG, IL - (February 2005) - With HEIDENHAIN Corporation's expansion of their economically-priced inductive rotary encoders series - the ECI/EQI 1100 Series --, more alternatives than ever are available for those using small servo drives and general applications with lower accuracy requirements. Common applications are in drive technology, robotics and general automation technology. Most recently, these applications were mainly satisfied with resolvers.
Resolvers are known for their robustness, but they cannot fulfill the demands of drive technology for simpler commissioning, an electronic ID label and diagnostic functions. HEIDENHAIN's newest inductive rotary encoders, on the other hand, with their inductive scanning principle and well-known EnDat interface, fulfill exactly these requirements, and are even superior to resolvers in terms of positioning accuracy, speed stability and control dynamics. Also the competitive pricing makes them a welcome alternative to resolvers.
These newest of rotary encoders without integral bearing are even smaller in size than HEIDENHAIN's past offerings in this arena. Now, the outside diameters of them are 38 mm; their length is less than 28 mm. The new HEIDENHAIN models are the ECI 1116 (an absolute singleturn encoder with a resolution of 16-bit) and the ECI 1128 encoder (an absolute multiturn which counts in 28-bit). The mounting of these encoders has been simplified as well.
These ECI/EQI rotary encoders are mechanically compatible with the optical variant, HEIDENHAIN's seasoned ECN/EQN 1100 series. The motor non-drive end shield and the electrical interface remain identical regardless of the choice between optical and inductive encoders, meaning that with them, the motor manufacturer can produce a large number of identical parts increasing overall production and lowering production prices. The same also applies to the subsequent electronics and connecting cables.
