Adjustable encoder pin is varied, such as three feet, four feet, six feet and so on, the definition of the pin is not the same.
Whatever the pin, adjustable encoder encoder has several parameters characteristics: a, conformity degree: also called conformity, namely patch adjustable encoder features and actual output function required by the theory of function characteristics conform to the degree.
Resolution: patch adjustable encoder is one of the main factors that influence the accuracy of resolution, it is used in the moving contact on the winding resistance variation caused by every turn mobile and the percentage of the total resistance.
Three, mechanical life: patch adjustable encoder pin definition after mechanical life also called wear life.
Are generally expressed in mechanical durability.
Adjustable encoder pin connection with encoder connection is the same as the ordinary, specific wiring diagram may refer to the volume of the wiring method and encoder encoder wiring diagram, super practical described here.
A, if the patch adjustable encoder center sliding contact C to encoder output of voltage when A client is + 12 v, when the encoder center sliding contact C to encoder output of voltage of - B side
Second, audio amplifier used for volume control connection when the patch is adjustable encoder center sliding contact C to encoder when A volume is the largest, when the patch is adjustable encoder center sliding contact C to encoder B minimum volume, C to B appears poor contact will appear the phenomenon of volume closed tightly.
