Kt Kingtronics Upgrades Trimming Potentiometers Packaging Box

Kingtronics is potentiometers manufacturer since 1990. Trimming potentiometers are Kingtronics' first products. On Kingtronics' trimming potentiometers body, we mark "Kt" due to insufficient space. Actually our registered brand in Hong Kong is “Kingtronics and Kt”.

 

Now, Kingtronics upgrades trimming potentiometers packaging box . There are 3 sizes of different packing box, which can be used for all types of trimming potentiometers .We choose blue as the color of Kingtronics. Our website, catalog, poster, envelope, company logo and all other things related to Kingtronics, we choose blue. Blue stands for our Kingtronics people spirit --- Innovation, efficiency and foucs

 

Compared with out previous one , we list all the strong products of trimming potentiometers on the box. Our brand name and contact way are also printed on it. Therefore, whether you are interested in other products of potentiometers, or have any inquiry, you can contact us rapidly.

 

Below link provides more information about trimming potentiometers, hoping it is helpful to you.

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.
