It is also capable of sensing changes in gravitational forces to accurately regulate the power flow to motors and other electronic devices.

Working Principle

The 91A2A-B24-D20/D20L’s working principle is based on the rotation of a fixed carbon element. When a user turns the knob to a specific position, the resistance between the two arms of the potentiometer is adjusted accordingly. This change in resistance is then transformed into a variable electrical signal, usually in the form of voltage, so that it can be used by other circuits. Besides varying electrical resistance, the potentiometer also produces a physical indication of its current setting, allowing for easy monitoring by the user.

The 91A2A-B24-D20/D20L is designed with two additional terminals located in the middle of the potentiometer. These two terminals are connected to the resistive element itself and are used as a control terminal for external circuitry. This enables the user to adjust the resistance of the potentiometer from outside of the device. This feature is especially useful in applications where the user needs to adjust the resistance remotely.

Takeaway

The 91A2A-B24-D20/D20L is a highly versatile rotary potentiometer that is uniquely tailored to meet a wide range of precise applications. Its working principle is based on the rotation of a fixed carbon element, which is transformed into a variable electrical signal, allowing for tight control and monitoring. Besides being a potentiometer, the 91A2A-B24-D20/D20L also features two additional terminals for external circuitry control.
