Optical linear encoders

Renishaw offers a wide range of high speed, absolute and incremental optical linear encoder systems, to meet the diverse requirements of industrial automation.

Renishaw's optical linear encoders provide zero mechanical hysteresis and excellent metrology. The unique filtering optics withstand a variety of contaminants such as dirt, dust and scratches. Renishaw's encoders ensure that customers' machines run reliably with little or no maintenance.

All linear optical encoder and interface combinations feature an integral set-up LED on the readhead, which speeds installation and removes the need for complex set-up equipment. The newly launched miniature ATOM linear encoder is ideally suited to a variety of space-critical motion control, inspection and metrology applications. Stainless steel spar/tape is provided in cut-to-measure lengths and glass spar, for ATOM, is available in defined lengths to 130 mm. All scale types have the option of self-adhesive backing, which eliminates drilling and tapping, saving time and money.

  • Press release: Renishaw on high with Airbus A380 Superjumbo Press release: Renishaw on high with Airbus A380 Superjumbo

    By virtually every measure of comparison, the new Airbus A380 Superjumbo, now under final construction in Europe, is the largest commercial aircraft in the world. Able to accommodate 555 passengers, and with a wingspan in excess of 260 feet, building the giant double-decker calls for some highly-innovative assembly techniques. One such technique is the use of several wing-panel assembly machines that depend upon Renishaw’s RG4 linear encoder systems for positioning accuracy. The four machines incorporate over 1 km of 40 micron scale tape, to determine the precise position of travelling ‘yokes’.

    A revolutionary mobile phone antenna has been developed by UK company Sarantel, based on the company's patented PowerHelix™ technology. When other conductors or the user’s hand or head are next to the antenna, performance is completely unaffected, unlike conventional antennas. The unique manufacturing process uses a special purpose machine from Finnish company Citam Assembly Automatics Oy, fitted with Renishaw linear encoders to give very high accuracy.

    Special equipment has recently been installed at the University of Southampton by Ionoptika Ltd., for research into one of the most demanding of applications; micro-machining. Among the highly specialised suppliers involved is Renishaw, whose RG2 scale and RGH25 UHV readheads provide the crucial means of positioning for the nanometric movements required. People outside this discipline often find it hard to comprehend just how minute such work is – for example, Ionoptika’s full company logo can be etched 20 μm wide on a typical metallic screen mask.
