Original Press Release:

ETEL’s DXR+ Offers Entry Level Rotary Module to Semiconductor and Electronics Industries

ETEL is proud to introduce the DXR+, the newest member of its direct drive rotary module portfolio. For years, ETEL has offered a DXR rotary table as an accessory to its motion stages and now, with important design changes, the DXR+ is now available as a stand-alone entry level rotary module featuring a compact design, light mass, and large hollow shaft which provides the right performance-to-cost ratio for mid-end applications in semiconductor and electronics.

The DXR+ has the exact same physical characteristics as its predecessor, the DXR, but brings major improvements in terms of stiffness which has a direct impact on the control bandwidth of any XY stage that is supporting it.

The new DXR+ sports a toothless ring design, similar to an ironless linear motor but in a rotary shape, ensuring zero-cogging along with cross-roller bearings providing high moment load capacity and high stiffness. It is equipped with a Numerik Jena RIK4 encoder with 18,000 lines per revolution that can be read as either 1 VPP or a TTL signal output.

It is designed for electronic and semiconductor applications that can benefit from bidirectionnel repeatability of ±2 arc sec, position accuracy down to ±3 arc sec after calibration, and position stability ±0.2 arc sec.

Like any other standard modules from ETEL (ZT, Z3TH, RTTB), the DXR+ can be mounted on any standard XY platforms. The DXR+ is a one-degree-of-freedom module allowing unlimited angular travel. Nevertheless, as an option, travel can be limited to angular segments that are multiple of around 60°. The cleanliness level of a DXR+ ranges from ISO 5 down to ISO 1 under specific conditions.

ETEL S.A. is based in Switzerland with exclusive North American distribution through HEIDENHAIN CORPORATION in Schaumburg, IL. As a leading international supplier of direct drive and motion control components and integrated systems, ETEL supports high tech industry with linear motors, torque motors, positioning stages, and motion controllers/systems.
