Company Press Probably the Thinnest Encoder in the World
28 February 2005
A group of Cambridge, UK , scientists has contacted the Guinness Book of Records to claim the record for the world's thinnest position encoder. At 50 microns, about 2 of these encoders can fit within the thickness of a typical piece of paper.
The encoders are based on a new electromagnetic resonance technology which has been invented, developed and patented by Zettlex Ltd., a technology start-up from the heart of Cambridge 's Silicon Fen in the UK . Target applications include non-contact displacement encoders where cost, space, dirt or weight issues mean that traditional sensors cannot be used. Applications also include rotary knobs or linear encoders for user interfaces in tough environments such as off road vehicles, medical equipment and domestic appliances.
The technology's main components are based on simple printed circuit boards and, when conformally coated, require no mechanical housing. The sensors can be sealed to IP 68 and are rated from -40 to 125 Celsius. If flexible PCB's are used they can be extended to carry power and signals, thus avoiding the use of cables and connectors. With the application of contact adhesive to one side of the PCB, mechanical fixings can also be avoided when connecting to fascia panels.
The units are available in rotary, linear, 2-dimensioanl and 3-dimensional forms as well as a range of sizes. Linear versions range from 1mm to 2850mm.
Zettlex are marketing the technology as an inexpensive replacement for traditional sensors.
Dr. Darran Kreit, Zettlex's Chief Technologist says “We hope the market will find the slim, lightweight form of the sensor attractive, but I suspect the slim price tags will be the key to our success.”
