Description
PR18
SINGLE-TURN ROTARY
POTENTIOMETERS
The PR 18... single-turn, housed in a metal case, rotary carbon control potentiometers. It comprises a carbon
resistive track fitted on a resin modified paper base. Base diameter of potentiometers is 18 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 the PCB or soldering pins.
Applications
Potentiometers are widely used in electronic audio-video equipment, electric domestic equipment and outer control
elements.
