The Tokyo RV24YN 20S B502 is a high-quality single-turn rotary potentiometer designed for precise variable resistance control in electronic circuits. Manufactured by Cosmos Tokyo (Tocos), this component features a durable carbon film element housed within a circular metal casing, offering reliable performance for applications ranging from audio equipment to industrial control systems. The B502 marking indicates a resistance value of 5kΩ with a linear taper (B-type), ensuring smooth and predictable adjustments. The 20S suffix denotes a specific shaft configuration, while the three solder lug terminals (marked 1, 2, and 3) facilitate easy integration into printed circuit boards or point-to-point wiring setups.

Built for stability and longevity, the RV24YN 20S is engineered to handle up to 2W of power dissipation, making it suitable for moderate-power applications. The component’s construction includes a corrosion-resistant metal housing and a precisely engineered carbon track that delivers accurate resistance changes with minimal noise. Whether used for volume control, speed regulation in mobility scooters, or calibration in test equipment, this potentiometer provides a dependable solution for engineers and hobbyists seeking a robust, single-turn variable resistor.
