Encoders for motion control news

LinACE is a heavy-duty absolute linear encoder that is designed for integration into hydraulic, pneumatic and electromechanical actuators as a feedback element for position or velocity. The system has an accuracy of ±5 µm and users can achieve full closed-loop control, significantly improving safety and performance. LinACE is a completely novel approach to linear position feedback which is designed and manufactured by Renishaw’s associate company RLS.

With many countries moving to high-speed, fibre-optic broadband, there is a significant challenge to replace the mass of existing underground cables quickly and easily. The replacement of cables is made particularly challenging by the fragility of individual glass fibre strands and of the sheathed fibre-bundles, which cannot be simply pushed or pulled into ducts. Renishaw’s magnetic encoders help to provide a rugged solution to this extensive problem.

Renishaw's new RoLin non-contact magnetic encoder system is designed for embedded miniature motion control in high-volume applications in a wide range of industry sectors including semiconductor, science/medical, military/aerospace, and industrial automation.

Renishaw's RESOLUTE™ absolute optical encoder is now compatible with the Mitsubishi serial communications protocol in linear encoder formats. This allows RESOLUTE to be used with Mitsubishi’s MELSERVO-J4 range of servo amplifiers, which are regularly used in industries such as electronics assembly, flat panel display (FPD) manufacturing, factory automation and general motion control applications.

Renishaw's RESOLUTE™ absolute optical encoder is now compatible with the Panasonic serial communications protocol in linear encoder formats. This allows RESOLUTE to be used with Pansonic’s MINAS A5 range of drives, which are often employed in industries such as electronics assembly, semiconductor processing and flat panel display manufacturing.

The digital age has led to a quantum leap in astrophotography, making even the furthest galaxies accessible to professional astronomers and observatories. Now, thanks to Astrosysteme Austria (ASA), helped by Renishaw technologies, even keen amateurs can observe and photograph these remote solar systems at an affordable price.

Renishaw to launch its new RESOLUTE™ ETR (Extended Temperature Range), true absolute position encoder at the DSEI military exhibition, 13th-16th September 2011, ExCeL London.

Renishaw’s new RESOLUTE™ ETR (Extended Temperature Range) encoder brings all the benefits of the revolutionary RESOLUTE absolute, fine pitch angle encoder to harsh, low-temperature applications. With operation guaranteed down to -40 °C (-40 °F) in non-condensing environments, RESOLUTE ETR is highly suited for use in demanding applications such as telescopes, scientific research, military and aerospace.

Renishaw's new encoder pocket guide highlights the range of encoders, including incremental and absolute versions of both rugged magnetic encoders and precision optical encoders, and products for ultra-high vacuum (UHV) applications.

Known for its nano-motion stages for biomedical, semiconductor and photovoltaic applications, ALIO Industries depends on Renishaw's TONiC optical encoders for the accuracy and repeatability needed to drive its True Nano™ 'six degrees of freedom' solution for linear stages.

Renishaw's new absolute linear and rotary encoders revolutionise position feedback

ABTech Manufacturing creates five-axis platform for nanometer/sub-arcsec processing around its ultra-precision air bearings and Renishaw SiGNUM™ position encoders

Vistec Lithography’s (previously Leica Microsystems) VB300 e-beam lithography tool is a development of the highly successful VB6 series introduced in 1993.  In designing the new tool, Vistec identified that a reduction of noise-induced positional errors would significantly improve tool performance. Through a combination of improved mechanical rigidity and integration of the Renishaw RLE20 differential interferometer based encoder system, these errors are now expected to be 3 nm.
