Rotary Potentiometers, Rheostats

The 73JB2K is a type of rotary potentiometer and rheostat that is used to accurately measure and control the electrical current, voltage, and resistance in a wide range of applications. The potentiometer is a device consisting of three terminals (pins) and a rotary knob or dial which can be turned to vary the resistance between the terminals. The rheostat is a three-terminal device that uses the same rotary mechanism as a potentiometer, but uses two terminals to vary the resistance between them.

Application Fields

The 73JB2K can be used for a wide range of applications that require precise control over the voltage, current, and resistance. Common applications include: power supplies, regulators, amplifiers, industrial controls, audio/visual equipment, digital/analog instruments, industrial robotics, and communications equipment.

Working Principle

The 73JB2K functions by using a rotary knob or dial to precisely adjust the resistance between two terminals. When the knob is turned, the resistance in the system changes, which affects the voltage, current, and resistance output of the system. The change in resistance is determined by the amount of resistance between the two terminals. This change in resistance is what allows the user to precisely adjust the current, voltage, and resistance output of the system.

The rotary knob also has a detent notch which helps the user keep track of the position of the knob. The detent allows for a more precise control of the voltage, current, and resistance output. The device also features an adjustable stop which allows the user to limit the travel of the knob, preventing accidental or unwanted adjustment of the system.

Conclusion

The 73JB2K is a versatile device that can be used to measure and control the current, voltage, and resistance in a wide range of applications. Its rotary mechanism allows for a precise adjustment of the resistance, and the adjustable stop feature limits the travel of the knob, preventing accidental adjustment of the system. With its range of uses and adjustable features, the 73JB2K is an invaluable tool for any application requiring precise control over the current, voltage, and resistance output.
