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.
