Slimline encoders claim world record
Encoders based on a new RF technology target applications in noncontact displacement encoders where cost, space, dirt or weight issues mean that traditional sensors cannot be used.
A group of Cambridge scientists has contacted the Guinness Book Of Records to claim the record for the world's thinnest position encoder At only 50um thick, the encoders are based on a new RF technology which has been invented, developed and patented by Zettlex Printed Technologies

Consortium conceives rugged encoder
A UK consortium has developed what it claims to be the world's toughest position sensor based on a novel radio frequency (RF) technique.
Target applications include noncontact 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 medical equipment, domestic appliances and oil and gas equipment.
The technology's main components are based on printed arrays of conductive ink and, when conformally coated, require no mechanical housing.
The sensors can be sealed to IP67 and are rated from -40 to +200C.
If flexible substrates 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, annular, linear, two-dimensional and three-dimensional forms as well as a range of sizes.
Linear versions range from 0.1 to 2700mm.
Zettlex is marketing the technology as a cost-effective replacement for traditional encoders and LVDTs. Request a free brochure from Zettlex Printed Technologies ...
