Slide Potentiometers

Slide potentiometers are a type of electric device used to measure the magnitude of voltage at a particular point. They are a form of resistor which can be adjusted using a straight or curved sliding bar to vary the precise amount of resistance. Slide potentiometers are generally used to measure the voltage of DC current, but can also measure AC current for some applications. Generally, the current is measured at the center pin of the potentiometer.

The PDV15-21D-102B is a common slide potentiometer. It is a single-turn, 15-watt, 2-pole model and is the most popular, used in a wide range of applications. This potentiometer is mainly used in motor control systems and control panels for industrial and commercial appliances. The PDV15-21D-102B is also capable of measuring voltage. It has a 0 to 10K ohm range measuring 10 volts.

The PDV15-21D-102B works on a sliding principle, whereby a third central pin receives current which is converted to voltage. The voltage is then regulated by a resistance element on the central pin which controls the output voltage. Internally, the third pin is connected to a slider which is physically moved up and down the central resistance element. This, in turn, changes the level of voltage present at the output.

The PDV15-21D-102B has a low noise level, excellent electrical insulation, and high resistance stability. It is also capable of withstanding up to 85°C temperatures and has a long life span of up to 5 million cycles. The potentiometer is also resistant to shocks and vibrations.

When it comes to installation, the PDV15-21D-102B is fairly straightforward. The potentiometer can be easily installed on a printed circuit board, or a metal plate. All that is required is a simple wiring connection, and the potentiometer can be securely attached using the provided screws and nuts.

The PDV15-21D-102B is a highly efficient and reliable slide potentiometer suitable for a wide range of applications. It is capable of measuring voltage accurately and reliably, and is resistant to shocks and vibrations. Furthermore, it is simple to install and features a long life span of up to 5 million cycles.
