Reed sensors and Magnet sensors in Two wheeler applications
Motor bikes and other two wheelers normally use plunger type switches for detecting depression of the front and rear brake levers to switch the brake light on, and also for detecting the side stand position or throttle position. These plunger type switches are purely mechanical, and they are likely to fail early due to sheer mechanical wear and also due to the harsh environmental conditions. Reed sensors are the only devices that are hermetically sealed and completely safe to use even inside fuel tanks and they are molded, which means they can withstand higher shock and vibration limits, as well. Reed Sensors also have the added advantage of working well and are very durable in dirty environments without much change in actuating distance when the right magnets are selected for use. The basic principles of position sensing remain the same and a Reed Sensor fitted on a fixed surface, with a magnet fixed on the movable surface ensures a good life. Such a combination can be used for any of the above listed motorbike applications.
