Magnet sensors for Tension Monitoring in Coil Winders
Coil Winders help wind bobbins with Copper wire and these bobbins are used in various applications such as in reed relay coils, microphone, speakers, motors and generators. Coil winders, or coil winding machines, as they are also know, wind bobbins with the enameled Copper wire at very high speeds.
For the winding to be consistent as well as to ensure cable cuts are minimized, closed loop tension control systems are used. The wire, which is to be wound, is usually taken through a spring, which gives cushioning when winding on bobbins, which are not circular. The purpose of this arm is to also act as a buffer for feeding wire to the bobbin, during high speed winding.
A reed sensor mounted on this arm, with a magnet mounted on the lower limit stop ensures that the optimum tension level of the wire is always maintained during winding and this provides a closed loop system. Reed Sensors can also accurately count the number of turns on a bobbin, as it is being rotated, and this helps the controller maintain a uniform speed of winding across multiple spindles.
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.
