Trimming potentiometers manufacturer from China

Potentiometers are electric resistance components with three leading-outs and resistances can be adjusted as some relugulating rates.Potentiometers are made of resistancebody and removable wipers,output end can gain resistance and volatage which has relationship with displacement when wipers remove along with resistance element.Potentiometers can be used three-terminal components and two-terminal components,two-terminal components are variable resistors.

Potentiometers are one kind of variable resistors which is made of resistance element and rotating or sliding system.

Potentiometer is an adjustable electronic components. It is a resistance element and a rotating or sliding system.When a voltage is applied between the fixed electric shocks of resistance elements,the position of contact on resistance elements is changed by rotating or sliding,a voltage of a certain relationship with moving contact can be gained between moving contact and fixed contact.It is mostly used as a voltage divider when the potentiometer is a four-terminal device. Potentiometer is basically a sliding rheostat with several styles, it is mainly applicated in the speaker volume switch and power switch of laser head,potentiometers are adjustable electronic components.

In terms of material,there are wound potentiometers, carbon film potentiometers, solid-type potentiometers; according to the relationship of the output and input voltage ratio and rotation angle,there are linear potentiometers(linear) and function potentiometer (curvilinear relationship).Resistance, tolerance and rated power are main parameters.Potentiometers are widely used as user controls,such as volume controls and as position sensors,and may control a very wide variety of equipment functions.
