Rotary Potentiometers, Rheostats

A rotary potentiometer, or variable resistor, is a tool used for measuring the electrical resistance values in a circuit. The basic construction of a rotary potentiometer is a resistive wiper, which is twisted around a current carrying ring. The ring, or “wheel”, is typically made of some metal, such as aluminum, and provides a fixed resistance.The 53AAD-B28-E18L is a type of rotary potentiometer. It is designed for applications where the control, or variable element, can be set to any position within a range. It features a power resistor with a knurled or slotted shaft for manual rotation to adjust resistance value. It also has a “drop-in” plunger, which allows it to be installed and removed without structural changes.In terms of its working principle, the rotary potentiometer is a three-terminal device that utilises a sliding wiper to change the resistance between two of the terminals. When the knob of the potentiometer is turned, the wiper moves along the left side of the resistor, increasing or decreasing the resistance between the two terminals. Additionally, the wiper has a third terminal that can be used for either connecting a source or a load.The 53AAD-B28-E18L has a range of up to 0.2 ohms, with a tolerance of ±10%, making it particularly appropriate for precision applications requiring accuracy and reliability. It is also designed for rugged operation, making it suitable for many industrial applications.In summary, the 53AAD-B28-E18L is a type of rotary potentiometer ideal for precision applications. It features a rotary wheel and a knurled or slotted shaft for manual rotation, as well as a drop-in plunger for easy installation. This potentiometer provides an adjustable range of up to 0.2 ohms, with a tolerance of ±10%, and its working principle is based on a sliding wiper to adjust resistance values. It is suitable for many industrial applications and is designed for tough operation in harsh environments.
