A rotary potentiometer, or rotary pot as it is often called, is a type of mechanical device used for controlling the amount of power or voltage through a circuit. It consists of a circular disc, with a hole in the centre, and a fixed arm attached to the disc that is connected to a power or voltage source. When the center of the disc is turned, the arm rotates, changing the amount of power or voltage transmit through the circuit. The pot is usually attached to a knob or switch, allowing an operator to easily control the level of power or voltage.

Rheostats, on the other hand, are electrical components also used for controlling the amount of current sent through a circuit. They consist of a coil of wire wrapped around a cylinder, and are typically used to change the resistance of the circuit. When the coil of wire is turned, the electrical resistance of the circuit changes, causing the amount of power or voltage to be changed. Rheostats are commonly used to control the speed of electronic motors, such as those in fan motors.

The 84A1A-B28-J15L is an example of one of these components. It is a rotary potentiometer, with a 3/8-inch shaft, and a 20-turn knurled knob. This particular component is designed to be used in applications where a precise adjustment of voltage or power level is required. It is commonly used to control the speed of fan motors, or to regulate the flow of electricity in other applications.

The working principle of the 84A1A-B28-J15L is simple. As the knob is turned, the center of the disc will rotate, causing the arm to move in a circular motion. This causes the arm to increase or decrease its resistance to the flow of electricity, thereby controlling the amount of power or voltage transmit through the circuit.

In conclusion, the 84A1A-B28-J15L is one of several types of components used for controlling the amount of power or voltage in a circuit. It is a rotary potentiometer, with a 3/8-inch shaft and a 20-turn knurled knob, used for applications requiring precise adjustments. The working principle is based on the rotation of the center of the disc, which causes the arm to increase or decrease its resistance to the flow of electricity, thus controlling the amount of power or voltage sent through the circuit.
