BOURNS 93R1A Panel Mount Rotary Potentiometer 50kΩ Linear 2W

The BOURNS 93R1A-R22-A18L is a high-quality, single-gang, panel-mounting rotary potentiometer designed for precision control in a wide range of electronic applications. Featuring a robust metal plain bushing for secure mounting, this component offers reliable and durable performance.

Its core is a linear-taper cermet element with a resistance of 50kΩ and a ±10% tolerance, providing a stable and predictable response. With a generous power rating of 2W, it is suitable for circuits requiring higher current handling. The single-turn adjustment and linear taper make it ideal for applications where a direct, proportional relationship between shaft position and resistance is essential, such as in volume controls, calibration pots, and light dimmers.

This potentiometer is equipped with an L-pattern arrangement of PC pins for straightforward board mounting and features a 90° clockwise anti-rotating lug to prevent unwanted movement after installation. It boasts an essentially infinite theoretical resolution, allowing for very fine adjustment. The component is built to withstand challenging environments, with an IP40 protection rating against solid objects and an extensive operating temperature range from -40°C to 125°C.

The compact dimensions ensure it can be integrated into space-constrained designs without compromising on performance or reliability. As a part of the reputable BOURNS 93 Series, this potentiometer represents a dependable choice for engineers and hobbyists seeking consistent quality and precise control in their electronic projects.
