EATON E34 Series Potentiometers

What is the difference between a potentiometer and a rheostat?

A potentiometer is a variable resistor with three terminals, while a rheostat has only two terminals. The potentiometer controls the voltage in a circuit, while a rheostat controls the current.

How do I select the best potentiometer for my application?

Consider factors like resistance value, operating temperature range, mechanical life and electrical specifications (power rating & tolerance).

How to maintain a potentiometer?

• Keep the unit clean of dust & debris. Clean it with a soft, dry cloth.
• Store the potentiometer in a dry environment and protect it from exposure to water or other liquids.
• Over time, the connections between the potentiometer and the circuit can become loose or corroded, affecting performance. Check these connections periodically.
