39SB-1NB-103 is a type of rotary potentiometers and rheostats, it has a wide range of application fields and working principles. In this article, we will discuss the application fields and working principles of the 39SB-1NB-103, in order to provide a better understanding of its features and capabilities.

Application Fields of 39SB-1NB-103

The 39SB-1NB-103 is a rotary type potentiometer and rheostats and it can be used in many different application fields. It is typically used as a variable resistor for controlling current in electrical circuits, particularly when exact output values are required. They are often used when precise control of motor speed or voltage is required as they can be easily adjusted. Additionally, they are used as volume control elements in audio amplifiers.

The 39SB-1NB-103 is also used in the manufacturing process to measure distances, angles, displacements, and other physical parameters in machines and tools. It can also be used for measuring temperature and pressure devices. Additionally, the 39SB-1NB-103 can be used in pressure switches, start and stop controls, and other control systems for various applications.

Working Principle of 39SB-1NB-103

The 39SB-1NB-103 is designed with a contact wiper and a circular track having evenly spaced resistance elements. As the shaft of the potentiometer is rotated, the contact wiper moves along the track and the electrical resistance of the device varies accordingly. This variable resistance is what is used to measure the displacement of the shaft. The resistance is determined based on the position of the contact wiper on the track, which is determined by the mechanical output of the shaft.

The 39SB-1NB-103 is a reversible type potentiometer and its resistance value can be adjusted from zero ohms to its maximum rating. The resistance value desired can be written down, and then adjusted by rotating the shaft to the desired value. For example, the resistance value desired can be written down as 50 ohms, and then the rotary knob can be rotated to achieve a value of 50 ohms.
