Description

Encoder and regulator Technical Field The utility model relates to the technical field of electrical components, in particular to an encoder and a regulator. Background An encoder (encoder) is a device that compiles, converts, or converts a signal (e.g., a bit stream) or data into a signal form that can be used for communication, transmission, and storage. The encoder converts angular displacement, referred to as a code wheel, or linear displacement, referred to as a code scale, into an electrical signal. Encoders can be classified into contact type and non-contact type according to a read-out mode, and can be classified into incremental type and absolute type according to a working principle. The incremental encoder converts the displacement into a periodic electric signal, and then converts the electric signal into counting pulses, and the number of the pulses is used for representing the size of the displacement. Each position of the absolute encoder corresponds to a determined digital code, so that its indication is only related to the start and end positions of the measurement, and not to the intermediate course of the measurement. In the prior art, the surface metal parts of the encoder are tightly attached to the bottom of the PCB after being installed, which easily has negative effects on the performance of the electronic equipment, such as electromagnetic interference and electrostatic discharge, and causes functional failure.
