Hall-effect-sensors uses a technique where a difference of potential occur between semi conductor plates when they are exposed to a magnetic field. The base Hall-element uses the variation of the distance to the magnet to detect the angle, but more sophisticated solutions are also developed to meet the demands and increasing EMC-levels. With this contact less technique we can offer linear sensors, angular sensors (up to 360 degrees) and joysticks. The technique is used in several of our products and have also been used in some customized projects by Regal. In this area there is a quick and continuous development on the market, and we are following to be able to offer the best solutions to our customers.
