Rotary Potentiometers

Rotary Potentiometers are a type of adjustable electrical resistance component, used for measuring electro-mechanical position or providing an adjustable voltage divider. These devices consist of a rotor - a shaft that is free to rotate inside a static housing, with a resistive element or track that is mechanically coupled with the rotor, making contact with the rotating element. The result is that a varying voltage is generated as the shaft is moved, which can then be registered and/or utilised by a controller circuit or system.

Rotary Potentiometers may be either linear, logarithmic or dual-slope designs, depending on the application. In linear designs, as the resistor slides or rotates along the track, the resistance across the slider terminals changes at a constant rate with respect to the rotation angle. On the other hand, logarithmic designs are more suitable for audio applications as the changes in resistance are inversely proportional to the rotation angle, making the output softer when rheostat is near the end of its turns.

The PTV111-4415A-C103 is a specialized rotary potentiometer designed for automotive applications where precision is essential, such as in engine control units, fuel injectors, transmission systems, and electric parking brakes. It is a single-turn device with an absolute angular accuracy of +/- 0.05°, ensuring reliable operation in the most demanding conditions. The potentiometer is rated up to 150mA at 12V and operates over a temperature range of -40°C to +150°C.

Rheostats

Rheostats are electronically controlled adjustable resistors used for controlling the current flow in a circuit. Unlike potentiometers, rheostats are usually single-turn devices whose knob or slider can provide the necessary variations in resistance values as it is moved. They are mainly used as a variable resistor to change the amount of current going into and through the circuit.

Rheostats are commonly used when the circuit requires full adjustment of current. They can also be used to regulate the resistance value in the circuit, for instance when making fine adjustments to precise voltages and currents. The adjustment on the rheostat is typically made with a knob, allowing for easy and precise current control.

For automotive applications, one example of a rheostat is the PTV111-4415A-C103, which takes the form of a slider mounted on an electronically controlled resistance track that can be adjusted in a range of 0-5 volts with an accuracy of 0.01 volts. The device has an operating temperature of -40°C to +150°C and a rated current of 150mA at 12V.

The PTV111-4415A-C103 is designed for use in automotive systems such as engine control units, fuel injectors, transmission systems, and electric parking brakes, for providing a precise and accurate current adjustment in such applications.
