38PLABR10KLF10

Trimmer potentiometers, also known as fan trimmers, are a type of adjustable electrical resistor with a control knob to vary resistance. They are commonly used in electronics where a resistance must be adjusted and where no other adjustment mechanism is available. The 38PLABR10KLF10 is a motorized trimmer potentiometer composed of an embedded motor, a slider, a microcontroller, and a digitally controlled resistance.

Application Field

Given its rugged design and wide range of resistance, the 38PLABR10KLF10 is well suited for applications that require precise adjustment of a resistance. These include:

• Resistance trimming in audio, video, and communication circuits
• Voltage regulation in power supplies and resistive buttons
• Voltage level shifting and filtering in control systems
• Gain and voltage control in integrated circuit designs

Working Principle

At its core, the 38PLABR10KLF10 consists of a motor, a slider, a microcontroller, and a digitally controlled resistance. The motor is coupled to the slider, which moves along the resistance band to adjust the resistance. The motor is controlled by a microcontroller which takes in a digital input from the user in the form of up/down signals. The microcontroller then transmits signals to the motor, causing it to rotate either clockwise or counter-clockwise, depending on the signal received. As the motor rotates, the slider moves tin its accompanying resistance band, thereby adjusting the resistance. Once the desired resistance is achieved, the motor automatically shuts off, saving power.

The 38PLABR10KLF10 trimmer potentiometer is an invaluable tool for precision adjustment and is an invaluable asset in various industries, including automotive, medical, and aerospace. Its reliable performance and easy user control make it an ideal choice for application requiring delicate and precise adjustments.
