Rotary Potentiometers, Rheostats

Rotary potentiometers, also known as rheostats, are used for a wide range of applications. They can be used to measure resistance, voltage, current, speed, and a variety of other variables. In terms of technology, rotary potentiometers (Rheostats) are classified into two primary types: DC (static) and AC (dynamic) varieties.

The 7276R500L.25 rotary potentiometer is a variation of the traditional rotary potentiometer design. It consists of a single-turn potentiometer with a 25K ohm resistance rating. It is designed to withstand 500V under normal usage and is rated for the highest surge current of 15mA.

Application Field

The 7276R500L.25 rotary potentiometer is mainly used for the measurement of electrical signals, such as voltage, current, and resistance. It is often seen in applications where accuracy and reliability are paramount, such as in medical devices, power electronics, instrumentation, and automotive systems. Additionally, the 7276R500L.25 rotary potentiometer can be used as a volume or gain control in audio applications, and as a control for dimming lights.

Working Principle

The working principle of the rotary potentiometer consists of a mechanical contact and a resistor. The mechanical contact moves over a resistance element, which determines the amount of resistance the potentiometer has. When the shaft of the potentiometer moves, the mechanical contact moves, changing the resistance of the device.

The 7276R500L.25 rotary potentiometer also has a rubber stopper that serves to prevent mechanical wear on the potentiometer caused by constant usage. It also ensures that the mechanical contact remains in contact with the resistor element for an extended period of time, improving its accuracy and reliability.

Conclusion

The 7276R500L.25 rotary potentiometer is a highly accurate and reliable device that can be used in a variety of applications. It is perfect for measuring electrical signals as well as for audio applications and dimming lights. Additionally, its robust construction and superior performance make it an ideal choice for medical equipment, power electronics, instrumentation, and automotive systems.
