P261D-D13BS12CA2K

The P261D-D13BS12CA2K is a type of rotary potentiometer or rheostat, which is an electromechanical device for voltage or current regulation. This particular model is a linear taper rotary ceramic rheostat, making it suitable for applications that involve adjusting the resistance between two conductors. It can also be used for outputs of sound or music levels or for electronic volume control.

Working Principle

The working principle of the P261D-D13BS12CA2K rotary ceramic rheostat is relatively simple. It is composed of two metal contacts that are connected by a metal shaft. When the shaft is rotated, the contacts slide along the surface of a ceramic element, resulting in an increase or decrease in resistance. This adjustment in resistance will then cause a varying voltage or current output.

Application Field

The most common application for the P261D-D13BS12CA2K rotary ceramic rheostat is volume control, as it enables the user to precisely adjust the output levels or sound of a stereo system or other audio system. It can also be used to regulate the output levels of lighting or heating systems, as well as variable speed motors. Additionally, this model of rotary potentiometer is ideal for industrial applications as it can be used to control the flow of energy or water from one point to another.
