The PC-16 is a single-turn panel control potentiometer using a carbon resistive element with plastic housing and incorporated shaft. A wide variety of configurable options, such as ganging up to four modules, different shaft types and tapers, make the PC-16 suitable for numerous applications in the home appliance, industrial and automotive markets.
