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:

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.

Kingtronics (Kt) Trimming Potentiometer Cross Reference Guide 

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.
