Optical encoders boost speed and resolution

Renishaw's market leading RG2 (20um) and RG4 (40um) non-contact optical encoders offer more speed, more resolution, more features and increased reliability.

Renishaw's encoder products are recognised for their innovative filtering optics, high accuracy and high speed, and have become the established choice for many industrial applications.

With each new design, customers and designers push performance and specifications to the limit and to support this progress, Renishaw's encoder products continuously evolve and improve.

In the latest phase of evolution, Renishaw's market leading RG2 (20um) and RG4 (40um) noncontact optical encoders offer more speed, more resolution, more features and increased reliability.

Key improvements include: typically 20-30% faster than previous models; increased speeds now obtainable from slower controller inputs; lower SDE; 50nm resolution achieved directly from the readhead (RGH20, RGH22, RGH24 and RGH40); a wider choice of clocked outputs provides compatibility with a broad range of controllers; in addition to the setup LED and low signal alarm, the high resolution versions now include an over-speed alarm for added safety; a whole host of electronics upgrades guarantee a more robust signal and greater reliability; RGE and RGB high resolution interfaces are now reduced in size; and significant reduction in current consumption on high resolution options.

To mark these improvements, the new readheads feature a revised finish and new labelling.

As with all Renishaw products, a worldwide application support network and local stocks bring added confidence to system designers.
