Inductive Rotary Encoders suit automation applications.

Press Release Summary:

Manufactured with bearings, RIx 400 series bridges gap between resolvers and high-end rotary encoders in automated machine applications. Single- and multi-turn versions feature solid shaft and reach vibration load capacity of company's optical encoders with flange socket (150 m/s²). With this true absolute series, users can attain 16-bit single-turn resolution with measuring step of 20 angular seconds for speed control and accuracy of ±480 in. for positioning.

Inductive Rotary Encoders from HEIDENHAIN

Offered for Common Automation Technology Applications

SCHAUMBURG, IL - (June 2007) - In order to bridge the gap between resolvers and high-end rotary encoders in automated machine applications, HEIDENHAIN Corporation is now making available a line of inductive rotary encoders, the RIx 400 series with bearings. This new true absolute series of encoders is intended to broaden the possibilities of incorporating high quality, yet affordably priced rotary encoders from HEIDENHAIN, into an automated machine's motion control system.

By utilizing these inductive-type encoders, users are able to reduce their overall system costs. The RIx 400 series rotary encoders are available in both single-turn and multi-turn versions.

The first generation of HEIDENHAIN's RIx 400 series now enables users to attain a 16-bit single-turn resolution with a measuring step of 20 angular seconds for speed control, and an accuracy of ±480" for positioning. These encoders also reach the vibration load capacity of HEIDENHAIN's optical encoders with flange socket (150 m/s2), with later generations planned with higher loads if necessary.

The mechanical dimensions of these current RIx400 inductive encoders with a solid shaft are identical to those of HEIDENHAIN's optical encoders. Samples them are now available with EnDat 2.1 interfaces.

More information is available by contacting HEIDENHAIN at (847) 490-1191 or HEIDENHAIN CORPORATION, 333 E. State Parkway, Schaumburg, IL 60173. HEIDENHAIN can also be accessed directly via the web site at or e-mail at

HEIDENHAIN CORPORATION is the North American subsidiary of DR. JOHANNES HEIDENHAIN GmbH, a leading international manufacturer of precision measurement and control equipment.
