Trimmers Basic:

In its most common form, a trimmer is simply a device containing a resistive element, and a wiper, or adjustable tap, contacting the element. The wiper can be mechanically moved to vary the amount of voltage or resistance in the circuit. The resistive element is usually laid out in linear or a circular configuration:

Kt Kingtronics Applications of Trimmer Potentiometers


Example1: Flicker adjustment for LCD (Liquid - crystal display)
To adjust the reference voltage (VCOM) of LCD.
With inappropriate reference voltage, there will be flicker on LCD screen.
Use trimmer Potentiometers to adjust reference voltage for flicker restraining.

LCD has some flickers if the voltage is not suitable for LCD.
 

You can reduce the flickers when you adjust the voltage by using trimmer potentiometer.
 

Example2: Gain adjustment for Blu-ray, DVD, CD disc reading optical pick - up.

As record media Blu-ray, DVD and CD etc. usually be used, and we use optical pick - up for the data
reading and writing from disc. In an optical pick - up, there is a light - sensitive element to detect
reflected light from disc.And a trimmer potentiometer is used to adjust the sensitivity
of thislight - sensitive element.
 

Circuit example Playback system device (ex, DVD, CD, playback)

Example3: Sensitivity adjustment for sensor products.

There are all kinds of sensors around our life.

  • Lights turn on automatically when human be detected.
  • Smoke detector for fire preventing.
  • Parking assist system for distance from car to wall.
  • Product detection sensor in factory.
     

 For these sensors, trimmer Potentiometers are used for suitable sensitivity.
 

Kt Kingtonics Principle of Trimmer Potentiomerets

Principle of Trimmer Potentiomerets

A fixed resistor with a mechanism to change resistance construct a trimmer potentiometers. The principle is with the changing of resistive element length according a wiper sliding, the resistance will be changed. Use this method, with same sectional area, the resistance can be changed relative to resistive element length, and products can be manufactured in low cost.



            R: Resistance [Ω] 
            ρ: Resistivity [Ω/m] 
            L: Resistive element length [m] 
            S: Resistive element sectional area [m2]

  • The position of contact point decide the length of resistive element.
    Resistance between No.1 and No.2 (R12) will become higher if contact point become closer to No.3.
  • For easy introduction, we drew the resistive element like a rectangular solid. Actually, almost resistive element is round shape
    (U - shaped) .So the track of wiper is circle, and resistance is decide by the angle of wiper.
     

Change in resistance of Trimmer Potentiometers

There is the relationship between wiper position (angle) and resistance in below figure.

The output wave is besed on below conditions.
Resistive element is round shape (U - shaped) /Single - turn/No whirl - stop.

Construction
Single - turn, no whirl - stop typ    The relationship between wiper position (angle) and resistance 

 
Feature of Trimmer Potentiometers

By using trimmer potentiometers, it is no problem to set surrounding circuit constant roughly.
Would you please use trimmer potentiometers if it is difficult to decided on a resistance value in your circuit. You can design your circuit roughly and quickly as the result.
