Rotary Potentiometers and Rehostats are used to measure or adjust the amount of current or voltage flow through a resistance. The 3547B-1BB-103A is one such component that has a wide range of applications, and works on the principles of resistance, feedback, and conversion.

Potentiometers are resistors with an adjustable wiper terminal. By turning the shaft of the potentiometer, the resistance between the wiper terminal and one end of the resistor is adjusted. This can be used to measure the resistance between both terminals, or allow for the conversion of a physical parameter into an electrical signal. Rotary Potentiometers in particular are used in applications where flexibility and ease of use is required, and can be found in audio and communication equipment, light dimmer controls, motor control systems, and medical field devices.

A Rehostat is the same as a Potentiometer, but instead of a sliding contact on a resistive element, it uses a wire wound element with a single sliding contact for variable resistance. Rehostats are traditionally used as rheostats, for the purpose of controlling the intensity of electric current in a circuit or controlling voltage. They are most commonly used in light dimmer switches, the volume control of audio systems, and for resistance welding controllers.

The 3547S-1BB-103A is a special type of rotary potentiometer which uses conductive plastic for the resistive element. This type of resistor is more resistant to mechanical vibration, shock, and extreme temperatures, and is commonly used in audio passives, HVAC systems, automotive electronics, and load cells. This particular component is also designed with a knob to provide a visual indication of resistance setting, and has a 0.5W maximum power rating.

The working principle of the 3547S-1BB-103A is that when the wiper arm is connected to the flats of the resistor, the resistance between it and the other end of the resistor is measured. This resistance is analyzed through a circuit and a corresponding voltage, current, or resistance is determined. This value is then used accordingly in the device in which the resistor is installed, making it possible to measure and adjust the current or voltage flow.

Rotary Potentiometers like the 3547B-1BB-103A can be installed in many different applications and are used to measure the amount of energy passing through them or adjust the flow of current or voltage in a circuit. Rehostats are more limited in application and are primarily used for controlling the intensity of electric current or voltage in a circuit.
