Rotary Potentiometers


Series single-turn potentiometers PR-18 they are enclosed in a metal housing, with a resistive element in the form of a carbon track. PR-18 series potentiometers are made in three versions, which differ in the type of leads, both for PCB and for soldering wires. PR-18 series potentiometers can be equipped with a single-pole switch. Potentiometers with resistance tolerances of 5% and 10% are available on special request.
