Product Description

Stable quality 12mm stereo type rotary carbon potentiometer WH0122-1-18T 

12mm stereo type rotary carbon potentiometer is widely used in the world market.

This potentiometer has three pins, good in a breadboard or with a panel. It's a fairly standard linear taper potentiometer, with a 18teeth knurled shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are freight, so you can plug it into a breadboard or perfboard. Once you're done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

Rotary carbon potentiometers still have many applications for the Medical, Automotive and Measurement Equipment markets and many more.

Q:Are you the manufacturer?

A:Yes!Perpetual making over 100 varieties of products, specializing in the production of carbon potentiometer, wire wound potentiometer, rotary encoder,rotary band switch and so on.

Q:How Does a Rotary Potentiometer Work?

A:Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor, and the output voltage is the voltage drop between the fixed and sliding contact.

Q:What is a rotary potentiometer used for?

A:A rotary potentiometer is an adjustable electrical resistor that can be moved by means of a rotary motion. This allows control processes to be implemented in various electrical or electronic systems, for example for volume control in multimedia devices.

Q:How about your package?

A:Usually we packed in strong carton,if you have specail request,we also can pack by pallent.

Q:What is potentiometer taper?

A:Simply put, a potentiometer is a resistor. When you turn the pot, you change the level of resistance.

A potentiometer taper is the relationship between the position of the pot (as you turn it) and the corresponding output. This is important when using a pot as a volume knob because humans perceive volume changes logarithmically. This means that if you use a logarithmic pot (type A), the volume sweep is evenly distributed through the rotation of the knob. In contrast, if you were to use a linear pot (type B) for volume control, most of the volume changes will be "crowded" at one end of the turn.

Potentiometer is a resistance element that has three leading ends and the resistance value can be adjusted according to a certain change law. A potentiometer usually consists of a resistance body and a removable brush. When the brush moves along the resistance, the resistance value or voltage is obtained at the output which is related to the displacement.
The potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor, because its role in the circuit is to obtain and input voltage (applied voltage) into a certain relationship with the output voltage, so called potentiometer.
