Joystick potentiometers are potentiometers that are used when customers require devices with reliable and sensitive linear motion control. The commonly used series is the 252A124A40NA series, which is ideal for use in applications such as industrial machinery, mobile robots, pilot seats in aircraft, medical and laboratory equipment, gaming systems, and computer-controlled equipment. This article will take a closer look at the application field and working principle of the 252A124A40NA series.

The 252A124A40NA series is designed for demanding applications due to its ability to withstand temperatures as low as -40°C and as high as 125°C. It is also compact yet rugged, making it suitable for applications where space and robustness is of the utmost importance. Additionally, it is highly shock and vibration resistant, allowing it to perform reliably even in extreme and hazardous environments. Furthermore, it is equipped with a high total travel, which is adjustable between 60° and 350° depending on the customer’s needs.

In terms of its working principle, the 252A124A40NA series is a variable resistor that uses the wiper-controlled resistor principle. The internal construction is comprised of a conductive spindle, a wiper that sweeps along a resistance element, and three contacts on the printed circuit board (PCB) that carry its input and output signals. As the spindle is turned, the wiper changes the electrical resistance between the two contacts, which yields a corresponding voltage change at the output contact. This signals the computer, allowing it to accurately control the linear motion of the joystick.

The 252A124A40NA series is designed to provide reliable and sensitive linear motion control in a variety of applications. Its high temperature range, large total travel, robust construction, and wiper-controlled resistor principle make it highly suitable for applications such as industrial machinery, mobile robots, pilot seats in aircraft, medical and laboratory equipment, gaming systems, and computer-controlled equipment. By employing this joystick potentiometer, customers can rest assured that their machinery will be able to perform reliably and accurately even in the most demanding conditions.
