Vishay / Sfernice P16 Compact Panel Potentiometers

Vishay / Sfernice P16 Compact Panel Potentiometers feature a unique integrated design incorporating the potentiometer and knob in one assembly, with no accessories required. The mounting hardware and terminals are situated on the backside of the panel, reducing the required clearance to a minimum.

The Vishay / Sfernice P16 Compact Panel Potentiometers are fully sealed and have an IP67 ingress rating.
