A rotary potentiometer, also known as a rotary rheostat, is a variable resistor used to adjust current or voltage levels. It takes the form of a circular dial which contains a segmented circular track. This track is split into several sections, each of which can be adjusted independently. The current or voltage adjustment is made by moving a pointer along the track to the desired section, which changes the overall resistance of the device. This allows for the precise adjustment of specific levels of current or voltage.

The 81A1A-B28-A15L rotary potentiometer is a high-precision device used for full-range current or voltage adjustment in medical, data acquisition, and industrial control systems. It is designed to provide precisely regulated, adjustable currents or voltages, enabling accurate control in a variety of demanding applications. It is suitable for use in hazardous locations, including cleanrooms and areas that require special protection from dust, moisture, and vibration.

The 81A1A-B28-A15L has a current range of 0-20mA (maximum output of 25mA), and a voltage range of 0-30V (maximum output of 30V). The device includes a wide range of adjustable resistor configurations, temperature compensation, and control functions. It also includes a low noise and low impedance design which ensures high accuracy and reliability. The device is also self-powered, which eliminates the need for additional power supplies and reduces overall system cost.

The 81A1A-B28-A15L utilizes a unique working principle. It incorporates two sets of conductive discs to produce a desired current or voltage. The discs are located on opposite sides of the device, and are electrically isolated from each other. The contact between the discs and the internal connection forms a voltage divider. When the discs are adjusted along their respective tracks, the ratio between the two circles changes, altering the output voltage or current. This allows for precise adjustment and control of output levels.

The 81A1A-B28-A15L rotary potentiometer is ideal for a variety of applications in medical, data acquisition, and industrial control systems. It is a highly accurate device that is perfect for precise current or voltage control in hazardous or demanding environments. Its robust design and wide range of adjustable amps, volts, and wiring configurations make it an ideal choice for many applications. With its reliable performance and easy to use operation, it is the ideal device for accurate control.
