Encoder in often use a long time, may fail, need to replace a new encoder, you know how to correctly choose the right encoder to replace the original encoder?
In general, replace encoder should follow the following principles: (1) encoder volume, shape should be similar with the original encoder;
(2) the value can vary by 20% ~ 30%.
The original encoder for 470 kq, for example, you can use 510 k, 0 substitution;
(3) power rating of substitute encoder generally should not be less than the original encoder, if the encoder is used in signal control circuit,
Such as the volume, tone encoder)
Encoder, wattage can not consider;
(4) if the length of shaft and axle end handles processing (
Such as file oblique or cut, etc. )
, should be performed before installation, must not in post-processing on the machine, so as not to damage parts.
Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various types of encoder, widely used in audio encoder volume, air conditioning, electrical appliances, intelligent household.
With complete encoder multiple-choice, can provide customers with a axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom, looking for looking for electronic encoder manufacturers.
