The 6639S-1-202 is a precision potentiometer manufactured by Bourns, featuring a 2,000 ohm resistance value with ±15% tolerance and essentially infinite resolution for smooth, accurate signal control. It delivers independent linearity of ±2.0%, an effective electrical angle of 340° ±3°, and output smoothness of 0.1%, making it suitable for applications requiring high precision and excellent rotational life. The device operates over a temperature range of +1°C to +70°C, with a power rating of 1.0 watt at +70°C, and withstands 750 VAC dielectric voltage. With a rotational life of 10,000,000 shaft revolutions, low wiper bounce of 0.1 millisecond maximum, and rugged construction, the 6639S-1-202 is ideal for general-purpose instrumentation, control systems, and applications demanding cost and space efficiency combined with reliable performance.
