PTV09A-2030F-A103

The PTV09A-2030F-A103 is a rotary type of potentiometer so named because it creates a variable resistance with a rotating shaft and sliding contact. It is often referred to as a rheostat because it is used for adjusting the resistance in a circuit, hence the alternate name. While potentiometers are used to measure the variable (non-linear) resistance in a circuit, rheostats are instead used to adjust the variable (linear) resistance in a circuit.

A rotary potentiometer can be divided into two categories. The first type is the contact or linear potentiometer with a linear resistance range and fixed resistive value. It can be used in applications where accuracy of the resistance values is not a priority. The second type is the track precision or variable-resistance potentiometer which is designed for applications that require varying resistance values. This type of potentiometer has a non-linear or variable resistance range and a variable resistive value.

The PTV09A-2030F-A103 is a track precision or variable-resistance type potentiometer. It is a single-turn, 9-mm, shaft-type rotary potentiometer with a 10-mm threaded mounting hole. It features a two section ganged construction, with the first section consisting of an internal resistance of 30R and the second section having an adjustable resistance of 0 to 310R total. The resistances of both sections are variable depending on the rotational angle of the shaft.

The PTV09A-2030F-A103 has a tracking error of 0.05% of the maximum value of the potentiometer. Its design prevents shorting even when powered by direct current. It has an insulated shaft and housing, which prevents electrical contact with any metallic parts. The PTV09A-2030F-A103 is sealed to protect it from dust and water.

The PTV09A-2030F-A103 is designed to be used in applications such as light dimmer/power control circuits, voltage regulators and variable signal sources. It can also be used in servo control systems, motor control and pulse width modulation circuits, and alarm monitoring systems. It is suitable for industrial and automotive applications.

The working principle behind the PTV09A-2030F-A103 is based on the principles of the variable resistors. When a voltage is applied at one of the terminals, the current flows through the rotary wiper to the other terminal. The amount of current flowing through the wiper is dependent on the position of the rotary wiper. As the wiper is rotated, the resistance between the two terminals is increased or decreased. This allows the PTV09A-2030F-A103 to be used for controlling voltage, current, position, speed and various other parameters in a circuit.

The PTV09A-2030F-A103 is an example of a rotary potentiometer, or in some cases, a rheostat. It is a precision type potentiometer designed for applications that require varying resistance values. It is suitable for industrial and automotive control systems which require repeatable and controllable resistance changes. The working principle of the PTV09A-2030F-A103 is based on the principles of the variable resistors, where the current flowing through the wiper is dependent on the position of the rotary wiper.
