Product Name:Magnetic Absolute Encoders


Magnetic Absolute Encoder Overview: An encoder is a device that compiles  converts signals  data into a form of signal that can be used for communication, transmission  storage. An encoder converts an angular  linear displacement into an electrical signal, the former known as a dial, the latter known as a scale. According to the readout method encoder can be divided into contact  non-contact two; according to the principle of operation encoder can be divided into incremental  absolute two types. Incremental encoders convert displacement into a periodic electrical signal, which is then converted into counting pulses, with the number of pulses indicating the size of the displacement. Absolute encoders have a defined digital code for each position, so that the displayed value is only related to the start  end positions of the measurement   to the intermediate process. Magnetic encoders
