392JB2500

Rotary Potentiometers; Rheostats

When it comes to controlling the amount of electrical energy that flows through a circuit, components such as rotary potentiometers and rheostats are the go-to option. These components, while similar in function, use different operating principles. This article will discuss the application field and working principles of a 392JB2500 Rotary Potentiometer & Rheostat.

Application Field of a 392JB2500 Rotary Potentiometer & Rheostat

The 392JB2500 is designed for use in low-voltage control applications. This includes level control and volume control of consumer electronics, such as televisions, stereos, and CD players. It is also often used in automotive, medical, and marine applications. With a rating of 0.5 watts of operating power and a maximum operating voltage of 5 VDC, the 392JB2500 is an excellent choice for applications requiring precise and reliable control.

Working Principle of a 392JB2500 Rotary Potentiometer & Rheostat

The 392JB2500 contains a resistor with two stationary terminals and a moving terminal called the wiper. The resistor is split into linear sections, with each section having a different resistance value. The amount of resistance is determined by the position of the wiper – the further away from one end the wiper is placed, the higher the resistance. In a rotary potentiometer, the wiper can be turned clockwise or counterclockwise, affecting the resistance value. In a rheostat, the wiper can be moved along its linear range, changing the resistance in a linear fashion.

The 392JB2500 is a combination rotary potentiometer and rheostat. It contains 10 linear sections, each with a resistance value of 0 to 10 ohms, allowing for precise control over the amount of current flowing through the circuit. The 10 sections can be thought of as a linear range, so the 392JB2500 can also be used as a rheostat in certain applications.

The 392JB2500 is highly precise and reliable, providing excellent performance under a wide range of conditions. It operates over a temperature range of -40°C to +85°C and is rated for humidity levels up to 95%. It is available in a variety of sizes, weights, and configurations, making it an ideal choice for applications requiring precise control of electrical energy.

Conclusion

The 392JB2500 is an excellent choice for applications requiring precise and reliable control of electrical energy. It is a combination rotary potentiometer and rheostat, capable of providing precise control over the current flowing through the circuit. Its wide range of operating conditions and configurations make it an ideal choice for a variety of applications.
