Rotary Potentiometers, Rheostats are versatile in their range of applications. One such application is the 91R2A-R22-D10/D10L. The 91R2A-R22-D10/D10L is a multi-turn rotary potentiometer, most commonly used for volume control, either as a single or dual concentric pot. It is a 10W, 22 mm diameter electro-mechanical component, and is well suited to through-hole designs and requires minimal board space.

This rotary potentiometer has a range of features that make it versatile and reliable. Its low voltage and current requirements make it suitable for operating with a wide variety of power sources. It has a low temperature coefficient, meaning it is highly accurate when used over a range of temperatures. This also makes it suitable for use in medical, industrial, and automotive applications. With its IP67 rating, the 91R2A-R22-D10/D10L is dust-proof and waterproof, meaning it is well suited for outdoor or wet environments. It also has a long operating life, thanks to its high-quality components.

So what is the working principle of this rotary potentiometer? Essentially, it works on the principle of an electromechanical transducer. When the shaft rotates, it changes the resistance of the contact between the rotor and the stator, which in turn causes a voltage to be generated across the terminals. This voltage is proportional to the angle of the shaft in relation to the stator body, allowing the control of electrical parameters such as current or voltage.

The 91R2A-R22-D10/D10L is an excellent choice for a variety of applications and a highly reliable component. Its size and low cost make it suitable for use in mass production, while its durability and accuracy make it ideal for reliable control of electrical parameters across a range of environments. With its dust and waterproof capabilities, it is perfectly suited for use in outdoor and wet environments, ensuring long life and highly accurate operation.
