Eaton RMQ-Titan 4.7kΩ Rotary Potentiometer Front Mount, 232232 M22S-R4K7

Eaton’s M22 range of rotary potentiometers enable a user to regulate and change the current that flows through a circuit, these rotary potentiometers can be easily controlled by turning the adjustable spindle or knob. These potentiometers are panel mount with screw terminals for easy mounting inside control panels and other electronics.

A potentiometer is a variable resistor that increases or decreases the resistance in an application. Usually available as either digital or analogue, there are many different types of potentiometer but the two main types are rotary and linear.

• Linear - comes in a rectangle strip shape and can be pulled up or down for the required resistance, used a lot within sound systems for mic output or volume control.
• Rotary - the shaft is housed by a knob, you would find these on dimmer switches or speakers, and turning (usually to the right) will increase the resistance amplifying the output, whether that is light, sound or voltage.

Potentiometers have two terminals that are fixed to a resistive element (the track). The resistive element is typically wire wound or made from carbon, cermet or conductive plastic. The 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 flowing through the circuit changes.

This Eaton rotary potentiometer regulates the current that flows through an electric circuit. It features an adjustable spindle that uses precision twist-action to set its value and increase or limit the resistance and output. The unit is commonly used in circuits to control audio volume, lighting intensity and temperature. This potentiometer has a rating of IP (ingress protection) 66, which means it's dust-tight and protected from low-pressure jets of water.

• ATEX (explosive atmospheres) certification for safety in hazardous areas
• Shaft length of 32.9 mm and diameter of 29.5 mm for easy handling
• Maximum resistance of 4.7 kΩ offers powerful range
• Front mount with a 22 mm diameter mounting hole for simple and versatile installation

Potentiometers have three terminals. Two of them are fixed to a resistive element such as wound wire, carbon or conductive plastic. The third terminal is connected to a wiper. As the wiper moves along its track, the resistance changes, increasing or decreasing the circuit's current.

Both are three-terminal resistors that help control electric current flow. A linear potentiometer, instead of using a rotating knob or spindle to control the current, features a sliding contact and a linear resistor.
