50K Multi‑turn Potentiometer – Model 3590S 🎛️

The 3590S 50K multi‑turn potentiometer is a precision adjustable resistor designed for high‑resolution trimming of voltage and analog signals. Its smooth multi‑turn action enables fine control and excellent stability, making it ideal for calibration tasks in Arduino, Raspberry Pi (with ADC), and other microcontroller projects, as well as test instrumentation and industrial electronics.

🔧 Key Features

• 🎯 50 KΩ resistance with adjustable range from approximately 0–50 KΩ
• 🔄 Multi‑turn design for precise, high‑resolution adjustment over several rotations
• 🛡️ High durability and long mechanical life for repeated calibrations
• 📏 Compact form factor suited to dense layouts and modules
• 🧩 Easy integration: standard 3‑terminal device for use as a voltage divider or rheostat

📐 Technical Overview

• Type: Precision multi‑turn potentiometer (trimmer)
• Resistance value: 50K Ohm
• Adjustment: Multi‑turn for fine control and improved stability
• Terminals: 3‑pin configuration (end–wiper–end)
• Mounting: Suitable for panel or PCB integration (solderable terminals)

🧰 Applications

• Precision voltage tuning and calibration
• Audio equipment and signal processing
• Control circuits in industrial electronics
• Sensor calibration and measurement devices
• Setting analog offsets, thresholds, and gains in electronics components and modules

🧪 Use with Development Boards

• 🔌 Arduino: Wire as a voltage divider (ends to VCC and GND, wiper to an analog input) for precise ADC readings.
• 🐧 Raspberry Pi: Use with an external ADC module (e.g., MCP3008/ADS1115) since the Pi has no native analog inputs; reference the 3.3 V rail.
• 🧠 Microcontroller systems: Ideal for trimming references, tuning setpoints, and calibrating analog front ends.

📦 Package Includes

• 1 × 50K Multi‑turn Potentiometer (Model 3590S)
