Absolute encoder noise how to repair

　Household appliances in the absolute value encoder due to frequent use (such as recorders in the volume of the absolute value encoder is often repeated spinning), the use of a period of time is prone to failure. Absolute value encoder failure is relatively easy to produce in the machine on the performance, such as rotating the absolute value encoder noise, sound when big and small, power switch failure, etc., then the need for absolute value encoder maintenance and repair. 　　Carbon film and synthetic binary encoder application after a period of time is most likely to fail is noisy (especially non-sealed absolute value encoder with switch), the main reason is that the contact reed and the lead terminal reed between oil stains and dirt, or resistance film is worn (parts failure of a basic type) so that the contact resistance is not stable (explanation: solid stability; no change). Rope displacement sensor in accordance with the readout encoder can be divided into contact and non-contact two kinds. Contact type using brush output, a brush contact conductive area or insulated area to...
