P230-CEC22BR20K

A rotary or rotational potentiometer, also known as a rheostat, is a two-terminal device that produces a variable resistance when rotated. It consists of a rotary element which is connected to a resistance track and a number of contact wiper arms. The P230-CEC22BR20K is a rotary potentiometer and rheostat.

The P230-CEC22BR20K is a single turn rotary potentiometer with 20 kΩ resistance. The body is constructed of thermoplastic, has a diameter of 22 mm, and a length of 64 mm. The center hole is 5.4 mm in diameter. The resistance track is 10 turns, with a resistance of 20 kΩ from end to end (clockwise). The power rating of the P230-CEC22BR20K is 2 watts.

The application of the P230-CEC22BR20K includes:

• Electric motors
• Voltmeters
• Stereo systems
• Audio systems
• Electronic games
• Radio and TV tuning circuits
• Variable relays

The working principle of the P230-CEC22BR20K can be broken down into three main parts – the resistance track, the wiper arms, and the contacts.

The resistance track is a conductor which is connected to the two terminals of the potentiometer. As the rotary element is rotated, the resistance between the two terminals changes, creating a linear voltage divider circuit.

The wiper arms are connected to the rotary element and move along the resistance track, making contact with the resistance track at different points. The resistance between the wiper arms and the resistance track determines the amount of current that flows between the two terminals of the potentiometer.

The contacts are the electrical connections that bridge the wiper arms and the resistance track. The type of contact used depends on the type of potentiometer. The P230-CEC22BR20K uses a carbon contact for its low-voltage, low-current applications.

Ultimately, the working principle of the P230-CEC22BR20K is similar to any other rotary potentiometer or rheostat. By rotating the rotary element of the potentiometer, the resistance between the two terminals of the potentiometer is varied, creating a linear voltage divider circuit. This allows for precise control over the amount of current that flows between the two terminals, enabling it to be used in a variety of applications.
