Product description: 250 kOhm linear rotary potentiometer 1/5 W B250K - 5 pcs.
Carbon-coated linear rotarypotentiometerwiththree pin-outs that fit on acontactor board. Connected tomicrocontroller's analog-to-digital converter (e.g.Arduinoanalog inputs) it can be used as a knob-knob in user interface. Potentiometer has a nut and washer.
Rotary potentiometer - applications
Rotary potentiometer250 kΩlinear1/5 Wis a proposal that can be used in many electronic projects. The element allows you to control the supply of electricity by increasing and decreasing the electrical resistance, so you can control the intensity of various functions of devices (for example, light or sound).
The potentiometer can be used, for example, as part of a device intended for audio playback (as a volume knob), or to regulate light intensity in dimmers for lighting installations, as well as part of thermostats and many other devices equipped with a user interface with the ability to continuously control the intensity of operation.
The elements are sold in packs of 5 pieces.
