The sports and fitness and recreation industry has seen a lot of changes and have made their move from using analog instruments and gauges to intelligent electronic controllers which give the user a lot more information on calories burnt, distance run etc. Reed Sensors and Magnet Sensors are used in a variety of sports equipments for passing on signals to the controller which in turn do the processing and give the user intelligent outputs. With the advent of intelligent toys and engineering kits in the recreation space, reed switches are also used by hobbyists. Reed Switches can be used to make custom Sensors for use with toys such as Lego to sense rotation, position and temperature. Reed switches are also used in dolls and toys for position sensing. We have suggested recommended products for use in each application, but this does not mean that the other products in the same product category will be unsuitable. We have also classified individual applications into types and these guidelines will help select the right magnetic sensitivity and type of magnet to use from our range of products.
