| Contactless position sensors |
Measurement of angular position using variation of magnetic field amplitude induced by the displacement of a moving magnet has been intensively developed over the last fifteen years. However, these solutions have limits in terms of angular range and temperature influence.
The technology used by Piher is only sensitive to the flux density coplanar with the IC surface. This allows to decode the absolute rotary (angular) position from 0 to 360 degrees. It enables the design of high performance non-contacting rotary position sensors for both automotive and industrial applications whithout the limitations of potentiometric solutions (wear, electrical angle...).
In combination with the appropriate signal processing, the magnetic flux density of a small magnet (diametral magnetization) rotating above the IC can be measured in a non-contacting way. The angular information is computed from both vectorial components of the flux density (i.e. BX and BY). Then an output signal proportional to the decoded angle is produced. The output is selectable between Analog, PWM and Serial Protocol. A configurable switch ouptput is integrated within the sensor too.
Redundancy is also integrated in the circuit and furthermore you can request a dual-chip sensor for true full redundancy which comprises a dual switch output.
Piher rotary contactless absolute sensors can be sealed and flange mounted for easy positioning when necessary. They provide excellent repeatability, accuracy, resolution, linearity and high stability under harhs environment conditions such as vibration, shock, extreme temperatures / humidity, dither, moisture or dirt. Featuring a modular architecture, electrical & mechanical characteristics can be fully customised to customer΄s needs. Endless connector configurations are available too.
Piher is a specialist designer and manufacturer of true non-contact absolute sensors for use in harsh environments and custom product tailoring for use on Tier One and OEM platforms including contactless magnetic technology complete sub assemblies.

Sunon「Mighty Mini Fan & Blower 1cm Series」
Won Taiwan Excellence Silver Award 2010 with World Leading Innovative Mini Heat Sink Technology |
|
Sunon, the world famous mini fan leader, has been granted Taiwan Excellence Silver Award 2010 for its world leading innovative mini heat sink technology, making Sunon Mighty Mini Fan & Blower 1cm Series the only innovative product prize-winner in the electronic parts and components industry. Shih Yen-Shiang, the Minister of MOEA, emphasized in his speech in the award ceremony, the importance of mini motor to global industries and acknowledged Sunons brand marketing ability which is based on innovative R & D, exquisite design, and excellent quality, and the ability to promote international brand, saying that Sunon embodies the innovative spirit of Taiwan.
Sponsored by the Bureau of Foreign Trade and organized by the Taiwan External Trade Development Council, the Taiwan Excellence Awards selection has attracted 717 products competing for the prize. Sunons Mighty Mini Fan & Blower 1cm Series emerged out of the fierce competition and won the silver award. Considering that the selection process, which emphasizes particularly on the innovation value of the products in addition to their R & D, Design, Quality, and Marketing, is done by a selection committee consisting of many domestic and foreign scholars and experts through rigorous professional selection procedures including document review, product appraisal, manufacturer briefing, and on-the-spot examination, the prize-winning products not only demonstrate their excellent quality but also embody the innovation value of Taiwan Branding by their manufacturers.
The Taiwan External Trade Development Council will, in order to improve the acknowledgement of Taiwans industrial design, innovation value, and brands and create new business opportunities for winner products of the Taiwan Excellence Silver Award 2010, organize a global exhibition tour and set up Taiwan Industry Image Galleries to display these excellent products. Exhibitions will be held in Dongguan, Beijing, Tianjin, Jinan, Jilin, Nanjing of China and Hanover, Indonesia, Berlin, and Dubai to enhance the image of Taiwan Industry in the world.
As the lowest energy-consuming and thinnest fan in the world, Sunons Mighty Mini Fan & Blower 1cm Series can meet the heat dissipation and air convection requirements of next generation portable electronic products, making them the first choice for equipment such as new generation UMPCs, UPCs, projectors embedded in mobile phone, mini projectors, USB Sticks, helmet monitor, air detector, mini fuel batteries, temperature sensors. With Sunons Mighty Mini Fan & Blower 1cm Series, product development concepts will be transformed into physical forms and product size will be shrunk from small to mini.
Having been operating with its own brand for 30 years, Sunon always adheres to the business philosophy of Brand, Innovation, and Value. Sunon has won the National Invention and Creation Contribution Award 2009 and the National Invention and Creation Silver Award for its mini fan invention patents, and now, it is glorified by the Taiwan Excellence Silver Award 2010. We firmly believe that encouraged by the Taiwan Excellence Silver Award, Sunon will continue its innovative R & D on mini motors and demonstrate its international level R & D, Design, and Branding strength. |
