This very small adjustment knob has been specially designed for 1/2" miniature potentiometers used on narrow chassis. It can be mounted in a space-saving manner, and its attractive design ensures a harmonious front panel appearance. The MF connects the potentiometer shafts (3 - 3.17 - 4 mm Ø) via a flexible, integral cardan coupling that ensures constant torque. Despite its small size, the set values are easy to read. An effective lock prevents unintentional rotation. The round scale shows the angle change in 2/100 turns, the number wheel shows full turns.
