Rotary Potentiometers

A rotary potentiometer, or rotary rheostat, is an electrical device used to control the flow of energy in a circuit. The device consists of a conductive track, usually of metal, that has a fixed terminal at one end and a moving contact, or wiper, at the other end. The position of the wiper, or variable contact, can be changed to vary the resistance in the circuit. There are several different types of rotary potentiometers; each type has different characteristics and applications.

7486R10KL.25

The 7486R10KL.25 is a standard-size rotary potentiometer with a center-tapped 10 KΩ linear taper. It is ideal for use in applications where linearity is important, such as light dimmers and position sensing. It has a two-piece construction with a black plastic rotor and plastic housing. The housing is threaded for secure mounting. The resistor\'s durable construction allows it to operate in temperatures ranging from -20°C to +70°C.

Application Field and Working Principle

Rotary potentiometers are used in many applications, such as audio controls, lighting controls, and gas flow control. They are also used in industrial and scientific equipment. The 7486R10KL.25 can be used in applications such as light dimmers, audio level controls, temperature controls, and robotic actuator position sensing. It is designed to be mechanically robust and reliable.

The operating principle of this device is based on the basic laws of electricity. When the voltage is applied across the two terminals, current is allowed to flow through the resistance track between the two terminals. The position of the wiper determines the amount of resistance in the track; the greater the resistance the lower the current. By adjusting the wiper, the current can be changed to control the output.

The 7486R10KL.25 has a linear taper, which means that the resistance increases in a linear fashion as the wiper is moved. Therefore, it can accurately control the current in a linear fashion over a wide range. This makes it ideal for applications that require linear control, such as dimming lights or controlling the position of a robotic actuator.

Conclusion

The 7486R10KL.25 is a standard-size, 10KΩ linear taper rotary potentiometer. It is designed to be robust and reliable, and it is ideal for applications where linearity is important. Its two-piece construction and threaded housing make it easy to mount. The operating principle of the device is based on the laws of electricity; when the voltage is applied across the two terminals, the resistance between them changes depending on the position of the wiper. The 7486R10KL.25 can be used in light dimmers, audio level controls, temperature controls, and robotic position sensing.
