Rotary Potentiometers and Rheostats

The P16NP472MAB15 is a rotary potentiometer and rheostat, combining the two components into one device. A rotary potentiometer variable resistor has only a single wiper contact that is adjustable, while a rotary rheostat has two separate adjustable contacts. P16NP472MAB15 combines the two, allowing for adjustment between the two adjustable wiper contacts.

Application Field

A rotary rheostat and pot combination like the P16NP472MAB15 is well suited when an adjustable voltage divider is needed, and the application calls for two adjustable elements. It may also be used in applications where both a variable resistor and a rheostat are needed. The P16NP472MAB15 also includes features such as anti-rotation, adjustable torque, audible and tactile switches, and magnetic detents.

Working Principle

The P16NP472MAB15 is composed of two independent contact elements, one that functions as a potentiometer, and one that functions as a rheostat. Both the wiper contact of the potentiometer and the second adjustable contact of the rheostat are adjusted by a single, mechanically linked drive. As the device is rotated, both contacts are adjusted simultaneously, and the voltage divided between them. Depending on the specific device, the adjustable impedance range may extend from 5 to 250 ohms, with a power rating of 5 watts.

Special Features

The P16NP472MAB15 rotary rheostat and pot combination device also includes features such as adjustable torque, end detents, and magnetic detents. The adjustable torque feature helps prevent accidental adjustment of the contact elements. The end detents provide an audible and tactile indication of the position of the contact elements. Finally, the magnetic detents securely lock the device in place, as well as provide a resistive force that allows for fine-tuned adjustment.

Conclusion

In conclusion, the P16NP472MAB15 a form of rotary potentiometer and rheostat device combining both components into one. It is well suited for applications that require a variable resistor and a rheostat, and it includes features such as adjustable torque, end detents, and magnetic detents. The adjustable impedance range is from 5 to 250 ohms, with a power rating of 5 watts.
