Rotary Potentiometers, Rheostats are widely used in a variety of electronic applications, due to their simplicity and cost-effectiveness. The P140KV1-F20BR20K is one of the more advanced models and is especially capable for applications involving extremely high temperatures.This potentiometer is constructed of very durable ceramic and features sealed construction for increased safety. Additionally, the stainless steel shaft is particularly resistant to wear and maintains its strength in temperatures of up to 250°C. The P140KV1-F20BR20K also offers excellent protection against dirt and moisture. Unlike some of its predecessors, the stainless steel shaft is fully sealed from the circuit board and does not include any weak spots that could potentially corrode. The working principle behind the P140KV1-F20BR20K is relatively simple. It consists of two dissimilar electrical resistances connected in series. As a user manipulates the knob, the variable resistor changes its value and thus changes the overall resistance. More specifically, the P140KV1-F20BR20K can provide rotational angles of 90°, 180°, or 360°. As the user rotates the knob, total output is monitored and changed according to the amount of rotation. This makes the device especially useful for applications in which precision angle control is required. Overall, the P140KV1-F20BR20K is an effective and reliable component for a variety of applications. Its ceramic construction and sealed shaft provide excellent protection against wear and corrosion. At the same time, the rotary design allows for simple angle adjustment with superior accuracy and consistency.
