Description

The RX20 series variable resistor is a high-power adjustable component designed for demanding applications. With a rated power range from 10W to 10,000W, it is constructed using a chromium-alloy wire as the resistance element, ensuring stable performance and long service life. The resistor body is coated with a flame-retardant, high-temperature resin, except at the sliding contact area, providing superior insulation and reliability.

Equipped with a central rotating adjustment mechanism, the RX20 allows smooth and precise resistance tuning across a wide range of values. Its robust design ensures excellent resistance to humidity and consistent performance under harsh conditions. Additionally, this series supports multiple resistance configurations--flat and round wire elements can be combined in a single rheostat to meet customized requirements.

Engineered for versatility, high power handling, and adjustable precision, the RX20 Variable Resistor is ideal for laboratory, industrial, and electronic control applications.
