DESCRIPTION

The 3590P-2-502L is a precision wirewound potentiometer manufactured by Bourns, designed for use in human-machine interface (HMI) applications requiring accurate resistance adjustment and reliable performance. This model features a 5,000 ohm resistance value with ±5% total resistance tolerance, ±0.25% independent linearity, and a 3600° effective electrical angle, delivering high precision control over a full 10-turn rotation. The potentiometer operates across a wide temperature range of -40°C to +125°C with a temperature coefficient of ±50 ppm/°C, and includes mechanical specifications such as 0.85 N-cm maximum starting torque (unsealed), 45 N-cm minimum stop strength, and approximately 19 g weight. It is equipped with solder lug terminals, a metal bushing (3/8" × 5/16") with shaft diameter of 0.2497 inches, and supports 1,000,000 shaft revolutions with ±2% maximum total resistance shift under load life conditions. The device is RoHS compliant and ideal for applications requiring precise analog control, instrumentation, and industrial automation systems.
