Trimmer potentiometers are widely used in electronics, controlling the resistance value by varing the contact point.

The 201UR252B is a trimmer potentiometer, mainly used to adjust the resistance in various applications. It is used in volume controls to control the proportion of the signal which passes through, or in circuit which requires a variable resistor for testing and changing values. It is a multi-turn potentiometer, and it supports vertical and horizontal mounting to give engineers more design options. Additionally, it has two terminals and a slot in the surface.

Working principle: the working principle lies in its structure. When the knob of the potentiometer is turned, its contact runs to different positions on the resistance element. So, the resistance value between the two terminals is changed. Generally, a single element has sides composed of linear resistive material, and the surface is coated with carbon pin. When two different areas of the resistive element are connected, it will form a circuit with a certain resistance.

The 201UR252B provides a robust and highly reliable features. It has a light , stable bearing provide smooth rotation along with excellent click feedback to accurately position the contact on the element. The terminals have a large contact area in order to ensure reliable contact when engaged. ThisContact travel distance is 18 degrees per revolution and the number of turns is 28.The elements of the potentiometer can resist high temperature and its recommended operating temperature is -40 to +85 °C. The potentiometers also have high dielectric strength of 1000Vrms and a nominal pull strength of 8N.

The 201UR252B trimmer potentiometer is mainly used in adjustable voltage power supplies, TV sets, precision voltage stabilizers, various electronic instrument control systems. It is also used in products needing adjusting the sensitivity of sensors, or controlling the current of motors. The 201UR252B is a perfect choice for engineers due to its robust and reliable performance, as well as accurate and easy to use control for their projects.
