Rotary potentiometers and rheostats such as the PTV111-4215A-B502 are used in many applications. They are mainly used for adjusting the parameters of a circuit or the voltage or current flowing in it such as sound systems, audio mixers, consumer electronics, telecommunications, power supplies, medical devices, vehicle audio systems, heating systems, motors, and instrumentation.

They operate according to a simple principle: the voltage across the resistors is divided in proportion to the turn of the wiper and the resistance. As the wiper turns, the resistance between the wiper and the resistors increases, and the voltage between the wiper and the resistors decreases. This allows the user to adjust the parameters of a circuit or the power flow in it. In the case of the PTV111-4215A-B502, it is a single-turn, solid-state rotary potentiometer with a switching contact that operates together with the center wiper. It has a maximum operating voltage of 50V, a maximum resistance of 25kΩ, and a wiper current of 1 mA.

Rotary potentiometers like the PTV111-4215A-B502 are widely used in industrial applications such as DC and AC motor speed control, automatic brightness control, LED lighting dimming, and volume or tone control of audio systems. Rheostats can also be used to make a simple voltage divider, allowing for easy voltage adjustments. In addition, they can be used for impedance matching in radio frequencies, power control, and current limiting.

A rheostat uses a resistive element such as a metal wire or a metal foil deposited on a ceramic substrate to create a variable resistance. Rheostats are used in applications such as heating systems, DC motors, and variable speed drives. They have a power rating and maximum temperature rating, and operate according to the same principle as potentiometers.

The PTV111-4215A-B502 is a single-turn, rotatable, solid-state potentiometer with a center wiper with contact and a maximum voltage of 50V and a maximum resistance of 25kΩ. It is well-suited for applications such as controlling the volume or tone of audio systems, controlling the levels of DC or AC motors, and adjusting the brightness of LED lights. Its high level of accuracy makes it a great choice for industrial applications.

In summary, the PTV111-4215A-B502 from Bourns is a single-turn, solid-state rotary potentiometer with a center wiper and switching contact. It is well-suited for many industrial and commercial applications such as volume or tone control, DC and AC motor speed control, LED lighting dimming, and current limiting. It has a maximum operating voltage of 50V, and a maximum resistance of 25kΩ. It is also accurate and reliable, making it a great choice for a wide range of applications.
