Achieve ultimate accuracy in your electronic circuits with the 3590S-2 Precision Potentiometer. Designed for applications requiring fine-grained adjustment, this 10-turn wirewound resistor offers a high power rating of 2 Watts, making it suitable for both signal-level and power-handling tasks. Unlike standard single-turn pots, the 10-turn mechanism allows for incredibly small resistance increments, ideal for sensitive calibration and industrial control systems.
Multi-Turn Precision: Features a full 10-turn (3600°) rotational range for ultra-fine adjustment of voltage or current.
Full Range of Values: Available in standard industrial codes: 102L (1K), 202L (2K), 502L (5K), 103L (10K), and 203L (20K).
2-Watt Power Rating: Robust wirewound construction allows for higher power dissipation compared to standard carbon film potentiometers.
Low Linearity Error: Maintains a high degree of accuracy with a typical linearity of $\pm0.25\%$, ensuring the output remains consistent with the dial position.
Sealed & Durable: Housed in a rugged blue thermoplastic casing with a metal shaft, designed to withstand industrial environments and frequent use.
The 3590S-2 Multi-Turn Potentiometer is the industry standard for:
Lab Power Supplies: Precise setting of output voltage and current limits.
Motor Speed Control: Fine-tuning the RPM of industrial DC motors and servo systems.
Measurement Instruments: Zero-point calibration and sensitivity adjustments for weighing scales and sensors.
Radio Frequency (RF) Tuning: Adjusting sensitive transmitter or receiver parameters where single-turn controls are too coarse.
Model: 3590S-2.
Technology: Wirewound.
Termination Style: Solder Lugs.
What do the codes like '103L' mean?
These are standard industry codes for resistance. The first two digits are the value, and the third is the number of zeros. For example, 103L means 10 + three zeros, which equals 10,000Ω or 10K.
Do I need a special knob for this?
While standard 6.35mm (1/4") knobs fit, most users prefer a Counting Dial (Duodial). These specialized knobs track the number of turns (0–10) so you can see exactly where the potentiometer is set at a glance.
Is this better than a standard carbon potentiometer?
Yes, if you need precision. A standard pot covers its full range in 300°, making small changes difficult. This unit covers the same range in 3600°, giving you 12 times more control over the adjustment.
