WH206 B50K

WH206 B50K Linear Slide Potentiometer (Fader)

Product Overview

The WH206 B50K is a linear slide potentiometer featuring a straight-line sliding fader design, commonly known in the industry as a “fader.” It adjusts resistance values through the linear movement of its fader; the resistive element is arranged in a straight line, and the slider moves along metal rails, driving an internal brush to travel across the linear resistive layer, enabling precise resistance adjustment. This potentiometer offers excellent visual intuitiveness of resistance levels—simply by looking at the fader’s position, you can instantly gauge the resistance value. When multiple faders are installed side by side, it also supports simultaneous multi-finger operation with both hands, meeting the demands of professional scenarios requiring synchronized multi-channel adjustments.

Technical Principle

The WH206 B50K linear slide potentiometer operates on the principle of voltage division. Its core structure consists of a straight-line resistive element paired with a slider that moves smoothly along metal rails and an internal brush. When the operator pushes the fader, the slider drives the brush to move synchronously along the linear resistive layer, altering the contact point between the brush and the ends of the resistive element, thereby adjusting the output resistance value and achieving precise control over circuit levels and signal strength. Compared to traditional rotary potentiometers, the linear sliding design creates an intuitive linear relationship between resistance changes and fader position, allowing operators to assess the adjustment status without needing to consult additional scales.
