Rotary Potentiometers and Rheostats are some of the oldest pieces of electronic equipment and are still incredibly commonly used in a wide range of applications. The most popular type is the 132B20502 potentiometer, which is known for its excellent accuracy and reliability.

A potentiometer is an adjustable voltage divider, consisting of a rotatable contact, or wiper, that moves along a resistive element. When the contact is moved, the electrical resistance of the element changes and the output voltage is altered. This allows the user to easily adjust the output voltage by rotating the contact.

The 132B20502 is a particular type of rotary potentiometer that is commonly used for controlling power supplies, as well as for motor speed control and other types of audio and light circuits. It has two terminals which are used to input power and a variable center pin which outputs voltage. The center pin is connected to the contact, which then varies the resistance of the internal resistive element. By changing the resistance, the output voltage of the potentiometer can be adjusted.

Rheostats are very similar to potentiometers and work in the same way, except they don’t have an adjustable wiper contact. Instead, they use a fixed contact to apply a variable voltage to the internal resistive element. This allows the user to control the current flow and the resistance of the device. Rheostats are mainly used for adjusting electrical heating elements and for controlling motors.

The 132B20502 is popular due to its excellent accuracy and reliability. It is built with high-quality materials and has a very long lifetime with minimal maintenance. It also features an adjustable screw terminal for easy installation and adjustable resistance to fine-tune the output voltage.

In conclusion, the 132B20502 is a very popular type of rotary potentiometer and rheostat. It is known for its excellent accuracy and reliability and it is commonly used in a variety of applications. Its adjustable screw terminal makes it easy to install, and its adjustable resistance allows the user to fine-tune the voltage output.
