Encoder selection of technical parameters, must see!

by:HENGXIANG     2020-11-06
Encoder varieties, structure, installation and technical parameters of circuit designers in selecting the encoder to shall, first of all, according to the encoder in the circuit to determine the performance indicators, following the first consideration for the selection of the encoder technology indicators, everyone can watch. 1. Rated power. Encoder allow dissipation on two fixed end of one of the most high power as the rated power of the encoder. Should be paid attention to in the use of power rating is not equal to the center tap and fixed on the power. 2. Nominal resistance. Marked on the name of the product value, the series is similar to the series resistance. 3. Permissible error level. The measured value and the nominal value error range according to different precision level allows & plusmn; 20%,± 10%,± 5%,± 2%,± An error of 1%. The accuracy of precision encoders can reach & plusmn; 0. 1%. 4. Value change rule. Refers to the resistance with the sliding piece of contact Angle of rotation ( Or sliding trip) The change of the relationship between the change relations can be any functional form, commonly used have line and logarithm model and inversion of logarithmic type ( Exponential) 。 In use, suitable for linear encoder divider; Inversion of logarithmic type ( Exponential) Encoder is suitable for a volume control in radio, tape recorder, record player, TV. If can't find the similar product, when maintenance can be replaced straight-line, but should not be replaced with logarithmic type. Only suitable for logarithmic type encoder tone control, etc. Shanghai electronics is 27 years old encoder manufacturers, encoder models complete, completely can according to customer demand axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom. Factory has advanced production equipment and testing equipment, the quality of large cargo is easy, find find electronic encoder manufacturers.
