Rotary potentiometers and rheostats are components of passiveselective electronic components. Their main purpose is to provide weak electrical signals or to control the current used in circuits. Although they seem to perform similar functions, they have different structural characteristics, operation principles, and performance attributes. The application field and working principle of the51AAA-B24-B18L, a widely used rotary potentiometer in the market, will be explained in detail in the following sections.

Application Field

The 51AAA-B24-B18L has many applications in the manufacturing process as it is a passive selective electronic component. It is mainly used as a resistor that transforms an input signal, such as the voltage of a source, into an output signal, such as an output voltage, current, or resistance. It is a cost-effective option to use for processes that require low-level signal conversions and low noise levels. It is an ideal tool for controlling the magnitude of an incoming signal and regulating its level in applications that include audio systems, communication systems, and medical instruments. It is also used in many consumer products such as microwave ovens, portable radios, and television sets.

Working Principle

The 51AAA-B24-B18L is a passive component that works by altering the resistance, current, or voltage of an electron flow. It is composed of a rotor and a stator. The rotor is divided into segments like teeth which have different widths. A wiper is used to establish connection between the segments, as the rotor moves the wiper slides across the stator and that changes the resistance as well as the current or voltage output. The difference between rotary potentiometers and rheostats is that the former has an added contact point on the rotor to control the magnitude of the output signal, whereas the latter does not. The 50-60K rheostat in this component also provides a way for operational temperature range customization.

Conclusion

The 51AAA-B24-B18L rotary potentiometer is an ideal component for converting low-level input signals into output signals by altering the resistance, current, or voltage. When rotary potentiometers and rheostats are compared, the difference is that the former involves an extra contact point on the rotor that provides flexibility in controlling the magnitude of the output signal. Several applications of the 51AAA-B24-B18L include audio systems, communication systems, medical instruments, and consumer products. Its working principle involves the use of a rotor with segments and a wiper that slides across it to alter the resistance and control the output signal.
