• Calibrating the sensitivity of various sensors

Trimmer potentiometers are also widely used in automotive and robotics for setting parameters like speed, direction and force. In addition, they can be used in home electrical appliances, telecommunications systems, instrumentation, and so on.

Working Principle

The 89PHR10KLFTB trimmer potentiometer consists of a resistive element which is wound in a circular pattern with two leads connected to opposite ends. The resistance is adjustable by rotating a screw which is mechanically linked to the resistive element. When the screw is rotated, the resistive element moves along the circular pattern. As the resistive element moves, the resistance changes.

The changeable resistor works according to the law of Ohm, where the current passing through the resistor is determined by the applied voltage and the resistance. This means that by changing the resistance, the current passing through the resistor can be adjusted.

Conclusion

The 89PHR10KLFTB trimmer potentiometer is a versatile tool which is used for adjusting the resistance in electronic circuits. This type of potentiometer is suitable for a broad range of applications, such as, adjusting audio amplifiers, LED lights, power supplies, antennas, sensors, robotics, and many more. It consists of a resistive element which is mechanically linked to a rotating screw, allowing the resistance to be adjusted by rotating the screw. Now that you know more about the application field and working principle of the 89PHR10KLFTB trimmer potentiometers, you can use this knowledge to select the right type of trimmer potentiometer for your application.
