Description
PR24
SINGLE-TURN ROTARY
POTENTIOMETERS
The PR 24 series are single-turn, housed in a metal case, rotary carbon control potentiometers. They comprise a
carbon resistive track fitted on a resin modified paper base. Base diameter of potentiometers is 24 mm. Resistance
track can be linear-A, logarithmic-B, inverse logarithmic-C. Potentiometers are made single or tandem, with plastic
or metallic spindle. Terminals are designed for PCB or soldering pins.
Applications
Potentiometers are widely used in electronic audio video equipment, electric domestic equipment and outer control
elements in professional use too.
