Purchasing the encoder is not just only know a encoder type procurement, in addition to the shapes of encoder, we should also know about the technical parameters of the encoder, in order to choose the right encoder is applied to the product. Mainly to understand these, also not sure purchasing friends can look. Main parameters of the encoder has a nominal value, sliding noise, power rating, zero resistance, resolution, abrasion resistance, resistance change characteristics and temperature coefficient, etc. ( 1) Nominal resistance, zero resistance and the rated power is nominal value encoder on resistance, namely encoder the resistance between the two set pieces end; Zero resistance refers to the smallest value of encoder, which end with Ren Yiding end between the minimum resistance; Encoder rated power in ac, dc, when atmospheric pressure is 87 ~ 107 kPa, under specified temperature rating of the load for a long time continuously allowed by the maximum power consumption. ( 2) Resistance changes of resistance changes characteristic of encoder encoder feature refers to the resistance value encoder as the length of the moving contact or axis of rotation Angle changes, the relationship between the resistance characteristics of output function. There are three commonly used: 1) Exponential ( Z) 2) Logarithmic type ( D) 3) Linear type ( X) ( 3) The resolution of the encoder resolution encoder is also called the encoder resolution, for winding the encoder, when dynamic contact each moving a circle, the output of the encoder voltage variation and the ratio of output voltage for resolution. For the linear encoder winding, the reciprocal of the number of turns its theoretical resolution for the winding, and expressed as a percentage. Encoder, the total number of turns, the more the higher the resolution. ( 4) Encoder dynamic coder dynamic noise is when the encoder under the effect of applied voltage, the dynamic contact resistance in sliding, generated by electrical noise. Dynamic noise is the main parameters of sliding noise, its size and the shaft speed, the contact point between resistance and contact resistance, the resistor body resistivity of uneven changes, the number of moving contact point and related to the size of the applied voltage. Shanghai electronics is 27 years old coder manufacturer, specializing in the production of various types of encoder, rotary encoder, straight and smooth encoder, rocker encoder, switch, encoders, take the motor encoder, resistance, linear and encoder handle designs and sizes are available according to customer's demand to customize, encoder models complete, can perfect replacement brand encoder, both at home and abroad to find find electronic encoder manufacturers.
