Trimmer Potentiometers

The 68XR2MEGLF is a trimmer potentiometer that is used in numerous applications. It can be used to adjust resistance in many circuits, such as those used in electronic devices. This trimmer potentiometer is an ideal option for applications that require precise or repetitive adjustments.

What is a Trimmer Potentiometer?

A trimmer potentiometer is a variable resistor that has a sliding contact or wiper that rotates around a circular track. This contact is between two fixed contacts, one at the center and the other at the edge. The output voltage of the trimmer is determined by the position of the wiper arm around the circular track. The resistance between the two fixed contacts can be adjusted with the help of a small mechanical adjustment wheel or knob. The 68XR2MEGLF trimmer potentiometer is a single-turn design, which means that it has only one coil. It has an adjustable resistance from 30 to 450K ohms. The body size of the trimmer is 0.56 inch (14.2 mm) and the body is made of ceramic. It has a round metal rotary shaft and a plastic knob.

Application Field and Working Principle

Trimmer potentiometers can be used in a range of different applications. They are commonly used to adjust the volume and tone levels of audio devices, as well as to adjust the current limits in power supplies, the threshold levels in automatic measuring equipment, and the height settings of conveyor belts. Trimmer potentiometers are also used in circuits to control the gain of amplifiers, and to adjust the speed of motors in speed controllers. They are also used in devices where the same adjustment will be made multiple times, such as in voltage regulators, frequency synthesizers, phase shifters, and many others. The 68XR2MEGLF trimmer potentiometer is mainly used in audio applications, for adjusting the volume and tone of audio devices. The output voltage of the trimmer is determined by the position of the rotary arm, which makes it ideal for applications where precise adjustments are required. When the trimmer is used, an electric current flows through the fixed contacts and the output voltage is determined by the position of the wiper arm. The resistance between the two fixed contacts may be adjusted by turning the adjustment wheel or knob, which will allow for precise adjustments.

Conclusion

The 68XR2MEGLF is a trimmer potentiometer that is used in many applications. It is a single-turn design, and has adjustable resistances from 30 to 450K ohms. It is mainly used in audio applications, for adjusting the volume and tone of audio devices. It is ideal for applications that require precise or repetitive adjustments.
