New POSITAL Hybrid Rotary Encoders Combine Incremental and Absolute Functionality


POSITAL has introduced new models of its versatile IXARC magnetic encoders that combine incremental and absolute rotation measurement capabilities in a single, compact and highly robust package. Absolute encoders provide a control system with an accurate report of the rotational angle and rotation-count at a specific point in time, which makes them ideal for many machinery positioning tasks.

Air Bearing Stage and Systems introduced by PI at Photonics West

Precision motion leader PI (Physik Instrumente) has introduced their new air bearing stage and system capabilities at this year's Photonics West conference, to complement their comprehensive range of piezo nano positioning stages and hexapod micro positioning systems. With the 2014 acquisition of Nelson Air Bearing Products of New Hampshire, PI is building on over 200 man-years of in-house air bearing experience to offer linear, planar XY, and rotary air bearing stages to serve both the research and industrial markets.

POSITAL offers Programmable Rotary Encoders, convenient UBIFAST Programming Tool

POSITAL offers a powerful new programming capability and tools for their IXARC series of rotary encoders. With these new capabilities, the performance characteristics of these POSITAL encoders can be extensively modified through software changes, without requiring changes to physical components. This increases the versatility of these devices for end users and helps distributors offer a wide range of options without having to increase the number of models held in inventory.

COUNTEX Easy as 1-2-3 Three-piece, double cardanic Coupling

COUNTEX® is a three-piece, torsionally stiff coupling which was specifically developed for the zero backlash demands of measuring  and control applications. The double-cardanic operating principle of COUNTEX® minimizes the restoring forces in a compact design ideal for ac-comodating large shafts and short DBSEs.

Yaskawa releases the Z1000U HVAC Matrix Drive

The Z1000U HVAC Matrix drive provides extremely low harmonic distortion in a space-saving design, along with the same HVAC-specific features as the standard Z1000. This single component solution achieves excellent low distortion levels all by itself, completely without the need for additional countermeasures such as passive filters or multi-pulse arrangements.
