PR16

SINGLE-TURN ROTARY

POTENTIOMETERS

Description

The PR 16 are single-turn, metal cased, rotary carbon control potentiometers. They comprise a carbon resistive

track fitted on a resin modified paper base. The base diameter of potentiometers is 16 mm. Resistance track can

be linear-A, logarithmic-B, inverse logarithmic-C or type of M+N. Potentiometers are made single or tandem, either

with or without tap, plastic or metallic spindle. Terminals are designed for a PCB or soldering pins. Potenctiometers

can

positions.

Applications

Potentiometers are widely used in electronic audio-video equipment, electric domestic equipment and outer control

elements.
