91A1A-B24-B20L

Rotary Potentiometers, Rheostats offer an inexpensive solution to the field of control measurement, and are used in a variety of applications, with 91A1A-B24-B20L being one of the most wide-spread types. With its versatile use, let’s take a look at the field of application and working principle for 91A1A-B24-B20L.

Application Field

91A1A-B24-B20L is different from passive styrene film rotary potentiometers with regards to its application field as it is used for various applications such as volume, balance, tone, motor speed control in the audio sector, remote control, trim, gain and other user-programmable applications in the automotive, aviation, communication and medical sectors. This type of a rotary rheostat was also used to assemble and adjust electrical systems, so its application range is quite wide.

Working Principle

The 91A1A-B24-B20L operates through the process of resistance as it has a spindle that can be adjusted and its movement equals to the associated variable resistance, this adjustment is determined by the displacement of the contact between the rotor and the wiper wire. When the spindle is set to its maximum position, the resistance between the two contacts is completely eliminated. On the other hand, when at minimum position, the resistance between volts is greater thus requiring more effort from the user and resulting in a higher value.

In addition, when the rotary control is connected to a circuit, the terminals of the upper and lower end of the spindle, they are connected to a different contact and can be easily adjusted by the user and the wiper. The advantage of this is that, there is no need to unplug any wires or taking apart the system if the user requires any adjustment to be made. Other features of 91A1A-B24-B20L include a low temperature coefficient, low short-circuit current and high shock resistance.

To sum up, 91A1A-B24-B20L, which falls under the umbrella of Rotary Potentiometres and Rheostats, has a wide range of applications and works based on a resistance value. Through its spindle, the user can easily adjust resistance to the maximum or minimum depending on the application. So, it is a reliable and modern device with a handful of features and convenient functions.
