Working Principles and Internal Components of 3214X-2-205E Trimmer Potentiometer

The 3214X-2-205E trimmer potentiometer works on the principle of a variable resistor. This device consists of three main components, namely the resistive element, the rotor and the fixed contact. The resistive element is made of a resistive material, such as cermet or carbon composition, and its resistance can be adjusted by the rotor. The rotor is connected to the resistive element and is driven by a knob on the outside of the potentiometer. The fixed contact is connected to the resistive element and is used to provide the reference voltage or current to the resistor. The resistance value of the resistor can be adjusted by turning the knob.

Conclusion

The 3214X-2-205E trimmer potentiometer is a versatile single-turn trimmer device that can be used in a variety of applications and fields. It is commonly used to accurately and quickly set frequency, voltage, and current in a variety of electronic circuits. This trimmer works on the principle of a variable resistor and consists of three main components, namely the resistive element, the rotor, and the fixed contact.
