How to choose a suitable adjustable encoder?

Of modern electronic equipment is more and more widely, the application of adjustable encoder using conditions are mature, then under different conditions of use how to choose the appropriate adjustable encoder? Electronic summary for everyone. Conditions of a type, selection of high power circuit power wire wound encoder; Condition 2, a sound system of tone control can choose straight slide type encoder; Three conditions, power supply circuit reference voltage adjustment should be chosen fine-tuning encoder; Condition 4, communications equipment and computer used in the circle of encoder can choose patch type more encoder or lap encoder; Conditions of five, the transistor radio volume and power switch can choose small with rotary encoder switch of carbon membranes; Six, precision instruments, such as circuit conditions should be chosen in the encoder, precision to high precision line around the encoder or metal glass glaze encoder; Conditions of seven, when choosing the encoder, answer to choose according to the specific requirements of the application circuit of encoder in resistance material, structure, type, specification, the adjusting way; Conditions of eight, audio equipment tone control should be chosen with encoder inversion logarithmic type ( Old exponential) Encoder, volume control with encoder can choose logarithmic type encoder; Conditions of 9, according to the requirements of the device and circuit chosen encoder types and specifications, and according to the requirement of the circuit electrical parameter of reasonable selection encoder, including rated power, nominal resistance, allowable deviation, resolution, high working voltage, noise, etc. Shanghai electronic products co. , LTD. , specializing in the production of adjustable encoder manufacturers, 25 years experience in research and development production adjustable encoder, the product has been SAMSUNG, SANYO, PANASONIC, TCL, MICROSOFT, rambler, chaoyang, FORYOU Huayang gm) Desai, navigation, west wei, song, backgammon, galanz, midea and other well-known enterprises at home and abroad. Looking for looking for electronic encoder manufacturers.
