PTV09A-4220F-B503 Application Field and Working Principle

Rotary Potentiometers and Rheostats are commonly used in electronic systems for sensing and regulating currents. A rotary potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider, while a rheostat is a two-terminal resistor with a rotating contact used to control current. The PTV09A-4220F-B503 is a rotary potentiometer and rheostat with a 50 kilohm rating. It is designed to be used in applications including:.

• Measurement of slow moving signals in industrial and medical applications.
• Computer and high-precision instrument settings, including trim and offset adjustments.
• Automated machine control.
• Tuning circuits.
• High voltage measurement.
• Remote control devices.

The PTV09A-4220F-B503 has a unique design specifically intended to provide superior performance in high voltage applications. The device’s wiper contacts are encased in glass fiber for additional protection from high-voltage spikes. The unit features an All-Metal wiper, a wide mechanical angle of rotation, and a shielded construction. The potentiometer and rheostat are available in a wide variety of values and package sizes.

Working Principle

The rotary potentiometer is essentially a three-pole switch. It consists of a resistive track connected between two of its three terminals, and the third terminal (called the wiper) is connected to a sliding contact which slides along the resistive track. The resistance between the wiper and one end terminal is determined by the position of the wiper on the resistive track.

The rheostat is a two-terminal resistor with a rotatable contact used to control current. It consists of a resistive track connected between its two terminals. The resistance between the two terminals is determined by the position of the contact on the resistive track.

The PTV09A-4220F-B503 combines both a rotary potentiometer and a rheostat. It is designed so that one terminal is connected to the resistive track, while the other terminals are connected to the wiper and contact. The resistance between the terminals is determined by the position of the wiper and contact on the resistive track.
