Rotary Potentiometers, Rheostats

A rotary potentiometer, or rotary rheostat, is a type of adjustable electrical resistance component that is widely used in many different applications. The two main types of rotary potentiometers are the AC-coupled rotary potentiometer and the frequency-selective rotary potentiometer.

86A2A-B28-A18/R51L

86A2A-B28-A18/R51L is a rotary potentiometer manufactured by American Controls, Inc. It is a 2-slot, 20-turn rotary potentiometer with a base resistance of 1 kilohm and a maximum resistance of 10 kilohm. The total resistance of the device varies linearly with the number of turns. This device is designed to accommodate a wide range of frequencies ranging from 12 KHz to 500 KHz.

Application Fields

Rotary potentiometers are commonly used in a variety of applications, such as audio equipment, industrial controllers, and medical equipment. 86A2A-B28-A18/R51L is particularly well-suited for automotive and medical applications due to its rugged design and wide frequency range.In audio applications, the rotary potentiometer allows users to control the volume of their equipment without having to make adjustments to the actual sound levels. It uses the resistance of the potentiometer to control the electrical current and the volume level. The size of the resistance is adjusted by rotating the knob.In industrial controllers, the rotary potentiometer is used to control the speed and power of motors or other devices that require varying resistance. This allows users to manually adjust the speed of the motor or device without having to make physical changes to the device.In medical applications, the rotary potentiometer can be used as a position sensor to measure and adjust the position of surgical instruments. It is also often used as a control element in temperature adjustment systems, as the resistance of the potentiometer can be adjusted to regulate the amount of electrical current and the temperature of the system.

Working Principle

The working principle of the rotary potentiometer is relatively simple. The resistance of the device is adjusted by turning the knob which changes the amount of resistance in the circuit. When the knob is turned, the resistance of the circuit changes and this results in a change in the voltage across the circuit.The power rating of the rotary potentiometer is determined by its maximum resistance. The output resistance can be varied from 0 to the maximum resistance and can be adjusted using the external knob. This allows users to precisely adjust the resistance in the circuit.The rotary potentiometer is a versatile and reliable device that is widely used in many different applications. It offers precise control, high accuracy, and durability. 86A2A-B28-A18/R51L is an ideal choice for automotive and medical applications due to its wide frequency range, rugged design, and precision.
