Rotary Potentiometers, Rheostats is a type of electronic component used to measure electrical resistance and voltage. The 91R1A-R16-A20L is a type of rotary potentiometer and rheostat which is commonly used in a variety of applications. This article will discuss the application fields and working principle of the 91R1A-R16-A20L.

A rotary potentiometer is a three-terminal resistive device that incorporates two resistive elements inside a single unit. It is a single-turn potentiometer that is used to measure the input of an electric circuit. It is usually equipped with a rotary knob that can be adjusted to set the precise value of the variable resistor. The 91R1A-R16-A20L is a single-turn rotary potentiometer that is mainly used for controlling the output voltage of DC power supplies, preamplifiers, op-amps, and in other audio equipment. It is also commonly used in industrial applications as a knob resistive device.

A rheostat is a two-terminal adjustable resistance element that is used to measure the amount of electric current flowing through an electric circuit. The 91R1A-R16-A20L is a rheostat that is used in a variety of applications, such as frequency control, speed control, output current control, resistance adjustment, brightness control, and other applications. It is widely used in the automotive, robotics, and industrial automation industries.

The working principle of the 91R1A-R16-A20L is based on the variable resistor concept. The device features two resistive elements inside the body. The two resistive elements are connected at one end and the opposite ends of the elements are connected to the adjustable knob, which is used to adjust the resistance of the device. The two resistive elements form a variable resistor whose value is determined by the amount of rotation of the knob. When the adjustable knob is rotated clockwise, the resistance value of the variable resistor increases and when the knob is rotated counterclockwise, the resistance value decreases.

The 91R1A-R16-A20L is a robust and reliable device that is commonly used in a variety of applications. It is widely used in the automotive, robotics, and industrial automation industries due to its high durability and accuracy. It is also used in audio equipment for controlling the output voltage of DC power supplies, preamplifiers, op-amps, and other audio components. Additionally, it is also used for frequency control, speed control, output current control, resistance adjustment, brightness control, and other applications.
