Reed sensors in Radio-controlled Gliders and model Airplanes
Radio controlled aircrafts, gliders and helicopters come in various sizes from simple ones with few controls to more expensive ones with several controls for the flaps, yokes, and motor speeds. On the simpler models, the hand held controller uses joysticks radio frequency to communicate with the crafts but this is not a closed loop system for there is no feedback as to the exact settings on the craft. The more expensive models require feedback from the craft when the controller is used and this is where reed sensors are useful.
Reed Sensors are very light devices and can be used on these models in the flap areas to sense whether the flaps have been deployed properly and also to check the multiple angles of the flaps. The same principle can also be used to check if the under carriage is down so that the model can be landed safely. More complicated models use multiple reed sensors for sensing a host of other features.
Applications are classified as Position Sensing, Pulse Counting, Electromagnetic or Relay, Temperature Sensing or Magnet Biasing types. This application is classified as follows and the link gives more information on best practices to help select the most suitable AT band and matching magnet.
The Reed Switches and Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and our intention is to ensure end product durability and life. Although we wouldn’t want to restrict any of our products for use in only certain applications, the recommended products for use in this application are listed below.
