WH148 Dual Potentiometer 50K Ohm – 6-Pin, Dual Gang, Linear Taper

The WH148 is a dual-gang 50K ohm potentiometer designed for applications that require simultaneous control of two independent channels from a single shaft. It contains two carbon-film resistive elements housed in one compact body, providing six terminals and a linear taper (B-type) response. The shaft is round and measures 15.6 mm in length, making it suitable for panel mounting with standard knobs. With a resistance tolerance of ±10%, this dual potentiometer offers predictable and repeatable adjustment for audio volume control, lighting dimming, and general variable-resistance tasks. Because both resistive tracks share the same shaft, users can adjust two audio channels or two lighting circuits in parallel without additional components.

The carbon-film construction and metal housing provide durability for everyday use in amplifier circuits, control panels, and DIY electronics projects. This 6-pin dual potentiometer is a practical choice for stereo volume control and any design that requires ganged adjustment of two 50K ohm channels.
