Rotary Potentiometers, Rheostats, and the PTP902-130F-105B2 application field and working principle are all part of the same device. Potentiometers, or pots for short, are a type of electrical component which functions as an adjustable voltage divider. Rheostats are a type of resistor with one lead that can be changed manually by the user in order to control the level of resistance. The PTP902-130F-105B2 is a potentiometer manufactured by Pulse and has specific applications in the field.

What is the PTP902-130F-105B2? It is a single turn, 10Kohm, 0.1% accuracy, 1/4 watt potentiometer with quick connect terminals. The stem size is 6.35mm (1/4"), and the overall length is 10.05mm. It is designed for panel mounting and is rated for 440VAC and 85°C. It has a maximum power rating of 0.25W and its tolerance is ±10%.

The working principle of this potentiometer is quite simple. The adjustable contact wiper (or “slider”) moves along a resistive track, changing the position of the contact relative to the track. This alters the resistance between the two ends of the track, known as the “ends” or “terminals”. The result is that changing the slider’s position changes the voltage divider ratio, and this in turn changes the output voltage.

The PTP902-130F-105B2 has a wide range of applications. The device is typically used in audio equipment as a volume control, but can also be used in a variety of other applications. For example, it could be used to control the speed of a motor or fan, the brightness of a light, the rate of a chemical reaction, etc.

In addition, the PTP902-130F-105B2 can also be used as a rheostat. A rheostat is a type of variable resistor that enables the user to control the amount of current in a circuit. To use a PTP902-130F-105B2 as a rheostat, one would need to connect the wiper of the potentiometer to a separate terminal and the two arms to the power source. This will allow the user to adjust the current in the circuit by altering the position of the wiper.

The PTP902-130F-105B2 is a versatile device which can be used in both audio equipment and a wide variety of other applications. It has a wide operating temperature range, high accuracy, and is easy to install. While the device is mostly used as a potentiometer, its adjustable contact wiper makes it useful in a variety of applications as a rheostat as well.
