100K Precision Multiturn Potentiometer - 10-Turn 3590S Wirewound Pot

Product Description The 100K Ohm 3590S-104L Precision Multiturn Potentiometer is a high-accuracy variable resistor designed for professional-grade calibration and tuning. Unlike standard single-turn pots, this 10-turn helical design allows for exceptionally fine resistance adjustments across its 3600° mechanical travel. Utilising a fully sealed wirewound element, it provides superior temperature stability and a long operational life, making it the industry standard for industrial control panels, medical equipment, and high-end power supplies.

Key Features

• Helical 10-Turn Design: Offers 10 full 360-degree rotations for maximum resolution in setting specific resistance values.

• Stable Wirewound Technology: Minimises resistance drift over time and maintains high accuracy under varying thermal conditions.

• Fully Sealed Body: Rated for protection against dust and moisture, ensuring reliability in harsh industrial environments.

• High Power Dissipation: Capable of handling up to 2 Watts, making it suitable for both signal-level and small-load applications.

• Smooth Tactile Response: Precision-engineered internal wipers ensure low noise and consistent torque throughout the entire range.

Technical Details

• Linearity Accuracy: Features an independent linearity of ±0.25%, essential for precision feedback loops.

• Operating Temperature: Rated to function reliably between -40°C to +125°C for industrial and outdoor use.

• Insulation Resistance: Minimum of 1000 Megohms (at 500V DC) to ensure complete electrical isolation.

• Dielectric Withstanding Voltage: Can withstand up to 710V AC at sea level without internal breakdown.

• Mechanical Angle: 3600° +10° / -0° with robust internal end-stops.

• Shaft Material: High-grade stainless steel or nickel-plated brass for corrosion resistance and mechanical strength.

• Rotational Life: Engineered for 1,000,000 shaft revolutions, significantly outperforming standard carbon potentiometers.

• Temperature Coefficient: Low drift of ±50 ppm/°C ensures the set value stays constant as the circuit warms up.

• Mounting Hardware: Supplied with a precision hex nut and lock washer for permanent panel installation.

• Backlash: Extremely low backlash (max 1°) for repeatable and reliable tuning.

• Bushing Thread: Standard 3/8-32 UNEF thread compatible with most industrial control enclosures.

• Noise Rating: Low equivalent noise resistance (ENR) of 100 Ohms maximum during adjustment.
