Introduction

PDB185-GTR02-254C2 is a rotary potentiometer, and it belongs to a kind of rheostats. A rotary potentiometer is a device used to measure the magnitude of an electric current and the resistance of this device is adjustable through the rotation of a knob. A rheostat is a type of electrical device characterized by having an adjustable resistance.Application Field

PDB185-GTR02-254C2 is often used in a wide range of applications. For example, they can be used in electro-mechanical devices such as temperature control systems, heating elements, and fans to measure the intensity of current and adjust the resistance. Besides, They are also used in a variety of audio and video equipment. It can accurately adjust the signal level and eliminate distortion. Additionally, these devices can also be used in motor control, such as speed control, limit switch control, etc.Working Principle

The working principle of a rotary potentiometer, such as PDB185-GTR02-254C2, is based on a passive electronic component. This component consists of an adjustable tapping of the resistive track, which is connected to three terminals. The two outside pins provide an electrical current input and output respectively, and the third pin inside the resistive track is the third pin which taps the track. As the knob is rotated the resistance of the track is adjusted accordingly. In the case of PDB185-GTR02-254C2, the resistance can be varied from 0 to 254 ohms.The rheostats are connected to two constant supply lines. When the rheostats are in an open state, the current passes through them and the voltage at the second terminal is equal to the voltage of the first terminal. As the resistance is adjusted, the voltage at the second terminal is changed accordingly. Conclusion

PDB185-GTR02-254C2 is a rotary potentiometer belong to a kind of rheostats. It is used in variety of application fields, such as temperature control, audio and video equipment, motor control, etc. The working principle is based on a passive electronic component, which consists of an adjustable tapping of the resistive track. It can adjust the resistance of the track from 0 to 254 ohms, and change the voltage at the second terminal accordingly.
