Schneider Electric 4.7kΩ Rotary Potentiometer 1-Gang Panel Mount, XB5AD912R4K7

From Schneider Electric this is the modular Harmony XB5 range of 22 mm diameter complete Potentiometers. The potentiometers have a modern ergonomic design giving you improved reliability for machines. Panels and processes. Easy to install, flexible, flush mounting, integrated resistor, hardwearing, cost effective suitable for all industrial applications. The Harmony XB5 Potentiometer range is an innovative, switch, control and signalling components.

A potentiometer (Pot) works through the two terminals they have, are fixed to a resistive element or what we may refer to as a track. A third terminal is connected to the wiper, which is a sliding contact. As the wiper moves along the track, the resistance changes and the current that is flowing through the circuit changes
