Reed Switches in Automobile Relays
Reed Switches find various applications in automobile electronics, for signal switching using reed relays, and in overheat protection using thermal reed sensors. Miniature reed relays, capable of switching high loads are used in automobile climate control circuits to switch on or switch off the heater and air conditioning circuits, for controlling the turn signals, and in applications for overload protection and safety. A well designed Reed Relay can consistently work at the require operate voltage range for hundreds of thousands of operations. In addition to Reed Relays, Thermal reed sensors are also used in automobiles to as a safety cut-out when the electronics on the control circuits cross a set temperature.
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.
