The 3500S-2-503L is a precision wirewound potentiometer manufactured by Bourns, designed for high-accuracy analog signal control and measurement applications. It features a 10-turn mechanical angle of 3600° ±10°, with independent linearity of ±0.20% and a standard resistance range of 50 to 200 kO. The potentiometer operates over a temperature range of +1°C to +125°C with a temperature coefficient of ±50 ppm/°C maximum, and includes a sealable bushing mount design with gold-plated solder lugs for reliable connections. With an IP 65 rating, low starting torque of 0.42 N-cm, and rotational life of 2,000,000 shaft revolutions, this component is ideal for precision instrumentation, control systems, and industrial applications requiring stable, repeatable performance.
