Rotary Potentiometers, Rheostats

The 91A2A-B28-D15/D15L, which can be referred to as a type of rotary potentiometer, is a small part that is designed for electrical use in many devices and appliances. This component operates with a variable resistor that is made from a resistive track, usually with a mechanical or manual adjustment. Commonly used in applications that require measuring and controlling the value of a purely resistive circuit, the 91A2A-B28-D15/D15L typically operates on low voltage and low current.

The 91A2A-B28-D15/D15L features a double-insulated body that helps to provide shielding from interference and also helps the component to anticonvect dust particles. The resistance path of this component is set with a variable resistor, which is adjusted by rotating a mechanical shaft within the housing. This type of adjustable part is also known as a rheostat. The 91A2A-B28-D15/D15L typically offers a voltage that ranges from 1 kilovolt to 5 kilovolts.

Types of 91A2A-B28-D15/D15L

There are two common types of the 91A2A-B28-D15/D15L parts: single-turn and multi-turn. The single-turn version is the most basic type and offers less accuracy than multi-turn components. The multi-turn variants are able to provide more precise and accurate readings as the resistance value is adjusted by turning a shaft for multiple turns. This allows the user to finely adjust the electrical resistance for a specific level.

Application Field

The 91A2A-B28-D15/D15L rotary potentiometer is commonly used in products and devices that require a high degree of control over voltage or current. This type of component is commonly used in a wide range of electrical and electronic devices, such as laboratory equipment, control units, and digital testing equipment. Additionally, this component is often used in computer equipment, amplifier circuits, motors, and industrial machines.

Working Principle

The 91A2A-B28-D15/D15L type of potentiometer works by using a constant current source to contain a resistive wire within a rotatable device. As the shaft of the device is adjusted, the resistance of the wire changes. This allows the user to precisely control the amount of current passing through the circuit. As the voltage and current are adjusted, the circuit behaves differently, allowing the user to control its performance. This type of adjustable device can also be known as a rheostat.

The 91A2A-B28-D15/D15L is a popular choice for many applications due to its accuracy, reliability, and low cost. This component also offers good environmental resistance and can withstand a wide range of temperatures and humidity levels. The use of a double-insulated body helps to increase the device\'s lifespan by protecting it from dust and interference.
