Working Principle

The HHV2WSFT-73-4M99 works by using a resistor element to limit the flow of electricity. This element consists of resistive nodes connected in a series. As electricity flows through the resistor, the electrical resistance created at each node limits the amount of current passing through. The resistance of the resistor is determined by the resistance range of the resistor. As the resistor is rotated, the nodes of the resistor move closer or farther apart, changing the resistance and adjustment the amount of current passing through.

Connection

The HHV2WSFT-73-4M99 is connected to a circuit board using two screws. The potentiometer is rotated using two screwdrivers inserted into the two corresponding slots. The resistance of the resistor is adjusted by turning the dial in either direction, allowing for precise control of the current passing through.

Conclusion

The HHV2WSFT-73-4M99 is an excellent single-turn trimmer potentiometer that offers a reliable bidirectional rotation life of 20,000 cycles and excellent electrical and mechanical stability. It is suitable for a wide range of applications, including but not limited to consumer and professional audio, communications and industrial control. The potentiometer is connected to a circuit board using two screws, and its resistance is adjusted by turning a dial in either direction.
