Rotary Potentiometers and Rheostats are two key components of electronics circuitry, both are generally specified by a name beginning with "6638S". The 6638S-1-103 is a type of potentiometer that is widely used in many applications. It is composed of a metal shaft with a resistive track connected to a three-terminal output socket. The track has a terminal at one end, and two other terminals with knobs are situated at the opposite end. A conducting wiper rotates across the two ends of the track, causing the resistance of the track to vary. As the wiper moves along the track, the resistance and the output voltage changes, and this variation is then used to control devices.

The 6638S-1-103 is used in a wide variety of applications, for example, in the automation industry, the potentiometer is used as an input/output device to control the speed and direction of motion. It is also used in the medical field where it can measure the speed and position of a patient, such as during physical therapy. In addition, this type of potentiometer is also used in audio and video applications to control the volume and sound/picture quality.

The main characteristic of the 6638S-1-103 is its total resistance, which is typically greater than 1 gigohm. Additionally, it typically has a power rating of around 10 watts and a linearity range of 10%, allowing for accurate resistance and output voltage variation. The 6638S-1-103 is also capable of high frequency operation, with a frequency rating of up to 100 kHz.

The basic principle of operation of the 6638S-1-103 is fairly simple. It works by having two electrically connected tracks that have a resistive track connected to a three-terminal output socket. The path of the wiper creates a resistive path between the two tracks, and as the track is rotated, the resistance of the track changes, which in turn changes the output voltage across the three terminals. By appropriately controlling the rotation of the wiper, the output voltage can be adjusted.

The 6638S-1-103 is a versatile, reliable and affordable electrical component that is used in a wide range of applications. It is composed of a metal shaft with a resistive track connected to a three-terminal output socket. As the wiper rotates across the two ends of the track, the resistance and the output voltage changes, and this variation is then used to control various devices. Its accuracy, fast response time and long term stability make the 6638S-1-103 a popular choice among audio and video engineers, automation professionals and medical personnel.
