Some friends design products to how to choose the encoder is very puzzled, encoder of choose and buy, need according to the requirement of the circuit to choose encoder, such as some encoder resistance materials, specifications, structure type and adjust the way to choose.
How to choose the encoder, you can choose from the following points, to determine the encoder supplier which to choose.
Choose encoder choose reasonable electrical parameters of the encoder in determining the locator device and circuit requirements after selective type specification, also according to the requirement of the circuit to rational selection of the point, the electric parameters, electrical parameters of the encoder mainly includes the rated power, nominal resistance, allowable deviation, resolution, high working voltage, noise, etc.
To choose encoder by resistance change law of different power circuit voltage regulation, amplifying circuit of working point adjustment, deputy brightness adjustment with encoder, linear encoder should be used.
Programmable control of audio equipments with encoder should use inversion logarithmic type encoder, but the volume control with encoder can choose logarithmic type encoder.
According to the requirements of the actual use of some such as precision instruments, such as to select the encoder circuit should be chosen in the encoder, precision to high precision line around the encoder;
The encoder, high frequency circuit can be used in carbon membranes;
Transistor radio volume and power switch can choose small with rotary encoder switch of carbon membranes;
The volume on the stereo audio amplifier can choose double coaxial encoder;
A sound system of tone control can choose straight slide type encoder;
Power circuit of the benchmark voltage regulation should choose fine-tuning encoder;
Communications equipment and computer used in the circle of encoder can choose patch type more encoder or lap encoder.
Shanghai electronics is a manufacturer specializing in the production of encoder for 27 years old encoder, encoder became some of the world famous enterprises designated products, customers throughout the world.
Looking for looking for electronic encoder manufacturers.
