PDV20-21P-504B

Slide Potentiometers

A slide potentiometer, or slide pot, is an adjustable electronic component that has a sliding contact for the rotary pot, hence the name. It is usually used to control the voltage and current going through circuits and is usually found in electronic appliances and industrial equipment. The PDV20-21P-504B is an example of a slide pot and it has a very specific application field and working principle.

PDV20-21P-504B Application Field

The PDV20-21P-504B slide pot is a manually adjustable, single-turn, linear-taper pot. It is mainly used in electronic equipment, such as audio amplifiers and attenuators. It is also used in electronic test instruments, like digital multi meters, for readout and adjustment of scale values. It is an ideal choice for applications that require a wide range of adjustability.

PDV20-21P-504B Working Principle

The PDV20-21P-504B slide pot works on the principle of a sliding contact. The pot’s contact is a wiper, which is connected to a taper-shaped track. The wiper slips along the track, increasing or decreasing the resistance at the contact as it moves along. This in turn adjusts the voltage and current passing through the circuit. In electronic devices, the slide pot is often used to adjust the volume, gain, frequency, or other parameter.

Conclusion

The PDV20-21P-504B is a single-turn, linear-taper slide pot that is widely used in a range of electronic devices and equipment. It operates on the principle of a sliding contact that increases or decreases the resistance of the circuit depending on its position. This makes it an ideal choice for applications that require adjustable voltage and current.
