This potentiometer features a helical (helipot) design, which provides a smooth and continuous resistance change as the shaft is rotated, making it an ideal choice for applications requiring fine adjustments.

The AR20K-L.25 Helipot Potentiometer has a 10-turn rotation, allowing for a total resistance range of 25 ohms, making it suitable for controlling voltages up to 25 volts. The resistance value is linear, ensuring accurate and reliable voltage control. The shaft of the potentiometer is marked with graduations every 1 ohm, providing clear indication of the resistance setting.

The AR20K-L.25 Helipot Potentiometer is built to the highest standards of quality and precision. It is constructed with a rugged epoxy-coated brass body for durability and resistance to corrosion. The wiper and shaft are made of high-purity beryllium copper, ensuring low contact resistance and long-term stability. The potentiometer also features a PTFE seal to prevent the ingress of moisture and contaminants.

The AR20K-L.25 Helipot Potentiometer is suitable for use in a wide range of temperatures, with a operating temperature range of -10 C to 60 C. It also comes with a 5-year warranty, providing peace of mind and assurance of the potentiometer's reliability and durability.

Overall, the Beckman AR20K-L.25 Helipot Potentiometer 304-1 is an excellent choice for laboratory and scientific applications that require accurate and precise voltage control. Its helical design, linear resistance, and rugged construction make it a reliable and durable component for even the most demanding applications.
