The 6637S-1-202 is a precision potentiometer manufactured by Bourns, designed for applications requiring high rotational life and excellent resolution with bushing mount configuration. It features a standard resistance range of 1 kO to 100 kO with ±10% tolerance, independent linearity of ±1%, and an effective electrical angle of 340° ±3°. The device delivers essentially infinite resolution with output smoothness of 0.1% maximum and operates over a temperature range of +40°C to +125°C, maintaining a temperature coefficient of ±500 ppm/°C maximum. With a rotational life of 10,000,000 shaft revolutions at no load and a dielectric withstanding voltage of 750 VAC minimum at sea level, this potentiometer is ideal for precision instrumentation, control systems, and applications demanding high reliability and long operational life.
