Multiturn Adjustment : 
Requires more than 360° mechanical adjustment to cause the wiper to traverse the total resistance element.

Terminal : 

An external member that provides electrical access to the resistance element and wiper.

Leadwire Type: (L)

Flexible insulated conductor.

Resistance Element :
A continuous, unbroken length of resistive material without joints, bonds or welds except at the junction of the element and the electrical terminals connected to each end of the element or at an intermediate point such as a center tap.

Adjustment Shaft :

The mechanical input member of a trimming potentiometer which when actuated causes the wiper to traverse the resistance element resulting in a change in output voltage or resistance.

Single Turn Adjustment :

Requires 360° or less mechanical input to cause the wiper to traverse the total resistance element.

Trimming Potentiometers:
An electrical mechanical device with three terminals. Two terminals are connected to the ends of a resistive element and one terminal is connected to a movable conductive contact which slides over the element, thus allowing the input voltage to be divided as a function of the mechanical input. It can function as either a voltage divider or rheostat.

Wirewound Trimming Potentiometer:

A trimming potentiometer characterized by a resistance element made up of turns of wire on which the wiper contacts only a small portion of each turn.

Non- Wirewound Trimming Potentiometer:

A trimming potentiometer characterized by the continuous nature of the surface area of the resistance element to be contacted. Contact is maintained over a continuous, unbroken path. The resistance is achieved by using material compositions other than wire such as carbon, conductive plastic, metal film and cermet.

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:

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.

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.

Hello my dear friend,
 
Wish you enjoy a nice weekend. :-)
 
This time our starring role is Trimming potentiometer, which is a kind of variable resistor and called trimmer and preset. It's meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. It can be used in many fields such as inspection machine, remote control, amplifier, controler, smoke detector...
 
Are you manufacturer in these fields or distributor for electronic components? Do you have demand for trimming potentiometer? Could you pls send me your request and I will reply you soon.
 
We Kingtronics is one of the oldest factories for trimming potentiometers in China. Our Trimming Potentiometer is ISO &SGS certified. With more than 20 years' development, our trimmer sell to many famous distributors, and can cross to many famous brands like Bourns, Murata and Vishay. We can offer you very good price and 3-4 weeks delivery.

A membrane potentiometer uses a conductive membrane that is deformed by a sliding element to contact a resistor voltage divider. Linearity can range from 0.5% to 5% depending on the material, design and manufacturing process. The repeat accuracy is typically between 0.1mm and 1.0mm with a theoretically infinite resolution. The service life of these types of potentiometers is typically 1 million to 20 million cycles depending on the materials used during manufacturing and the actuation method; contact and contactless (magnetic) methods are available. Many different material variations are available such as PET(foil), FR4, and Kapton. Membrane potentiometer manuafacturers offer linear, rotary, and application-specific variations. The linear versions can range from 9mm to 1000mm in length and the rotary versions range from 0° to 360°(multi-turn), with each having a height of 0.5mm. Membrane potentiometers can be used for position sensing.http://www.kingtronics.com/trimming-potentiometers/
