Rotary potentiometers, also known as digital potentiometers, are resistive devices that are used in a wide variety of applications. They use a wiper or rotating contact that moves along a resistive element to adjust the output voltage. The PDB182-E420K-103A is a rotary potentiometer that offers superior performance with excellent linearity, good temperature stability, high accuracy and resolution, and a long life cycle. It is widely used in precision measurement applications such as audiovisual equipment, industrial instruments, medical equipment, and automotive systems.

The PDB182-E420K-103A rotary potentiometer is rated to 20KΩ. It has a rotary contact terminal made of gold-plated nickel alloy. The terminals are corrosion-resistant and provide reliable electrical contact and low thermal emf. The potentiometer also has a compact size of 30x30x15mm. Its low profile offers space reduction in applications where space is a luxury.

The PDB182-E420K-103A rotary potentiometer works by adjusting a voltage divider. When the rotary contact is turned, a voltage divider is created between the resistive element and the rotary contact. This generates a variable output voltage which is determined by the actual position of the rotary contact. The output voltage range of the PDB182-E420K-103A is from 0V to 10V. The resolution of the output voltage can be adjusted by varying the value of the resistive element.

The PDB182-E420K-103A rotary potentiometer can be used in a variety of applications. Examples include adjusting audio amplifiers, sound and light intensity controls, motor speed controls, position sensing, temperature sensing, and many other applications. It can also be used as an adjustable voltage threshold where the output voltage is compared to a reference value and an alarm activates when the voltage reaches a specific value.

In summary, the PDB182-E420K-103A rotary potentiometer is an excellent choice for a variety of precision measurement applications. It offers superior performance with excellent linearity, good temperature stability, high accuracy and resolution, and a long life cycle. Its compact size and corrosion-resistant terminals make it ideal for applications where space is a luxury.
