Description
3590S-2-502L 5K Ohm 10-Turn Precision Wirewound Potentiometer
The 3590S-2-502L is a panel-mount precision potentiometer with a nominal resistance of 5kΩ and a 10-turn adjustment mechanism. Its multi-turn design provides much finer control than a standard single-turn potentiometer, making it suitable for calibration, measurement and control circuits requiring accurate manual adjustment.
The wirewound resistive element provides stable linear adjustment. A metal slotted shaft, threaded mounting bushing, nut and lock washer allow secure panel installation. Three solder-lug terminals provide access to both ends of the resistive element and the adjustable wiper.
This is an unbranded 3590S-style compatible potentiometer and is not listed as an original Bourns-branded component.

Terminal Function
- The two outer terminals connect to the ends of the 5kΩ resistive element.
- The centre terminal is the adjustable wiper.
- Use one outer terminal and the wiper for variable-resistor operation.
- Use all three terminals for adjustable voltage-divider operation.
Applications
- Measurement and test equipment.
- Calibration circuits.
- Industrial control panels.
- Adjustable voltage and reference circuits.
- Laboratory instruments.
- Audio and signal-level adjustment.
- Power-supply calibration.
- DIY electronic projects.
Installation Notes
- Confirm the terminal connections with a multimeter before installation.
- Do not exceed the allowable power dissipation.
- The maximum safe voltage depends on resistance, power dissipation and circuit conditions.
- Do not apply excessive force after reaching either mechanical end stop.
- Use the supplied nut and washer to secure the potentiometer to the panel.
