Working Principle

The PTD902-1010K-B203 is a rotary potentiometer that combines two technologies: a contactless Hall-Effect-Sensor and a conductive plastic element that contains a wiper terminal. The contactless Hall-Effect-Sensor is integrated into the component\'s body and provides the switching signal. The conductive element is made of two layers of conductive plastic with a wiper terminal that moves in a circular motion to provide a fluid movement, or gain, of the sensor\'s output voltage.

When the terminal rotates, it changes the current path between the conductive layers, altering the output voltage. By varying the output voltage, or gain, it is possible to control the speed of motors and to adjust signal levels. The PTD902-1010K-B203 is robust and offers a low transmission error of ≤2% and a resolution of 0.2%.

Conclusion

The PTD902-1010K-B203 is a robust and reliable rotary potentiometer manufactured by Electromech. This component is suitable for a range of applications, including signal control, motor speed control, and industrial automation. It combines a contactless Hall-Effect-Sensor with a conductive plastic element that contains a wiper terminal to provide a low transmission error of ≤2% and a resolution of 0.2%. This combination of features makes the PTD902-1010K-B203 an ideal choice for applications that require precision and reliability.
