i need a sensor/transducer to detect speed when a motorcycle braking system is being applied. can a rotary encoder suit this application? how?
get the metal detector and scour the desert.
You buy it from the store and use it in the desert. You could recharge it in the basement.

A rotary encoder is a gadget that converts rotary mechanical potential into electric powered potential. There are numerous varieties. some are relative encoders that use a chopped biphase easy source or magnetic pulse to % out stream and path. while means is bumped off, the learning regarding the placement of the encoder is lost. Absolute encoders have a coded wheel that has a special value for each place of the wheel. while means is lost and then restored the learning isn't lost. A knob is a undeniable gadget that appends to the shaft of the encoder to allow humanoid actual appendages to analogically control the encoder place, for this reason various encoded training to needed stages. In different words, that's the doohicky that sticks on the tip of the shaft so which you would be able to alter the quantity or bass/treble, etc.
A metal sheet cut into a complex pattern is affixed to an insulating disc, which is rigidly fixed to the shaft. A row of sliding contacts is fixed to a stationary object so that each contact wipes against the metal sheet at a different distance from the shaft. As the disc rotates with the shaft, some of the contacts touch metal, while others fall in the gaps where the metal has been cut out. The metal sheet is connected to a source of electric current, and each contact is connected to a separate electrical sensor. The metal pattern is designed so that each possible position of the axle creates a unique binary code in which some of the contacts are connected to the current source (i.e. switched on) and others are not (i.e. switched off).
