What are the criteria for selecting the right straight slip potentiometer sensor.2.4 ghz 15dbi outdoor omni directional antenna

　　(1) Select the potentiometer sensor according to the requirements of use

　　For example, power type wire-wound potentiometer sensor is used for high-power circuit; In the circuit of precision instrument standard, high-precision wire-wound potentiometer sensor, precision multi-turn potentiometer sensor or metal glass glaze potentiometer sensor should be selected; Medium and high frequency circuit can choose carbon film potentiometer sensor;

　　When selecting a potentiometer sensor, the resistance material, structure, type, specification and adjustment mode of the potentiometer sensor should be selected according to the selection of the application circuit, the potentiometer sensor and the specific requirements of the standard.

　　Parameters, including rated power, nominal resistance, allowable deviation, resolution, maximum standard operating voltage, dynamic noise, etc.

　　(3) Potentiometer sensor is selected according to the law of resistance value change

　　Resistance potentiometer sensors belong to the basic industry, in recent years, with Taiwan factories, such as Guoju, Wanquan and other companies began to enter China, the domestic resistance potentiometer sensor industry competition intensified. Most of the products brought by these Taiwanese companies are low-end products, especially the direct-slide potentiometer sensor is more low-end products, its patent level, or technical content is relatively low. In China, there are a number of resistance potentiometer sensor companies in the Yangtze River Delta and Pearl River Delta, but their economic choices, potentiometer sensors, and standard status are unbalanced. Like some options, potentiometer sensors, standard private companies, they can also earn some money, but the product grade is low, basically not much technical content. There are only a handful of state-owned enterprises left from the original state support, and most are now operating at a loss, with poor economic performance. The main reason is the lack of high-end products. Now there are many standard low-end products, and the shipments of low-end products are also large, we also export resistors, the number is also large, but the amount is not large. Because of its low technical content, and there are so many manufacturers competing in the direct slide potentiometer sensor, it is impossible to sell a good price.
