3290W-1-503

Trimmer Potentiometers are typically small adjustable electrically operated devices which allow the user to vary an electrical properties, such as resistance and therefore voltage or current. They are widely used in many electronic applications to precisely tune devices, such as amplifiers, antennas, radios, etc.

3290W-1-503 Application Field and Working Principle

Application Fields

The 3290W-1-503 is an industrial-grade trimmer potentiometer designed for precise adjustable settings in harsh operating environments. It is suitable for a wide range of applications, such as industrial instrumentation, communications, automotive, medical, and defense equipment.

Working Principle

The 3290W-1-503 contains a rotary element with two terminals on either side. Each side has an internal ratchet which adjusts the resistance with the rotation of the central knob. This knob is then connected to the element via a plastic shaft which transfers the knob\'s rotational motion to the element. As the knob is rotated, the resistance changes due to the change in the relative positions of the two internal ratchets.

The 3290W-1-503 has a locking feature which can be used to maintain the desired setting, even when the knob is subjected to vibration. It also features dial indexing for easy tracking of the potentiometer position.

The 3290W-1-503 is designed to provide reliable performance in extreme temperatures, vibration and humidity range. It is built with a robust construction to ensure long-term use in harsh industrial environments.

Conclusion

The 3290W-1-503 is a reliable trimmer potentiometer well-suited for industrial applications. It has a precise adjustable setting, accurate indexing, and a locking feature for vibration resistance. The potentiometer is designed to withstand extreme conditions, making it suitable for a wide range of industrial applications.
