Have you ever used a panel potentiometer when designing an electronic system? Where do you start when selecting a panel potentiometer?

As a variable resistor, the working principle of the potentiometer is very simple. It usually consists of an adjustable sliding contact and a fixed resistor. By moving the sliding contact, the resistance value between the two ends of the potentiometer is changed, thereby adjusting the voltage or current in the circuit. The panel potentiometer is based on the potentiometer and adds a switch mechanism (such as rotation, push, touch switch light) and related modules and components. It is installed on the panel of instruments and equipment to adjust and control various parameters (such as screen brightness, volume, speed, etc.). It is an intuitive and easy-to-use human-computer interaction element .

As a world-renowned electronic component manufacturer, Vishay also has a very rich portfolio of panel potentiometer products, which are widely used in heavy-duty vehicles (such as off-road tractors, excavators, cranes), avionics, medical and industrial fields. Among them, the P11 series is a very classic panel potentiometer product and is very representative .

Specifically, the P11 series panel potentiometer has three characteristics and advantages:

① Rich product types: The resistance modules cover the resistance range from 20 Ω to 10 MΩ. One P11 potentiometer can be configured with up to 7 resistance modules, providing 6 different taps including linear, logarithmic and anti-logarithmic , which can meet various design requirements.

② Diverse configurations: Provide up to 20 shaft designs and 8 sleeve types to cope with diverse application scenarios.

③Excellent reliability: With IP64 sealing level and high torque brake module, it can maintain stable performance under harsh replacement conditions.

After years of accumulation, the P11 series has now formed a large "family" with many members. No matter what application you are facing or what type of panel potentiometer you need, you can find a suitable solution from it. In addition, Vishay also provides customized options to meet the unique design needs of developers to achieve differentiated product development .

In order to help everyone fully understand the P11 series products and fully understand the functions and customization options provided when selecting panel potentiometers, Vishay has specially launched a Chinese technical white paper to provide more detailed technical descriptions. It can be said that starting with this white paper will be a shortcut to selecting Vishay panel potentiometers!
