Rotary potentiometers and rheostats are both types of variable resistors, and while they appear identical on the surface, their operating principles are quite different.

A rotary potentiometer is an adjustable resistance with three terminals, with one terminal connected to a resistance track which can be turned in order to adjust the resistance. This external resistance can be turned up and down to change the resistance within the device. This resistance can then be used to adjust the voltage or current passing through the device.

Rheostats are also adjustable resistors but operate on a much different principle. Rather than adjusting a rotating element to change its resistance, the rheostat works by increasing or decreasing the amount of current flowing through it. The resistance, in this case, does not change but the current is regulated by varying the voltage applied to the device. This makes rheostats suitable for use with high current applications.

The PTD901-2015K-A503 is an example of a rotation potentiometer, and it is commonly used in industrial, automotive, and consumer electronics applications. The device is designed with three terminals, a wiper and two ends, and it features an adjustable resistance track which can be changed by turning the rotary element. The rotation potentiometer is a linear device, which means that the resistance increases in a linear fashion as the rotary element is turned. The PTD901-2015K-A503 also features a low power consumption, making it suitable for use in low voltage applications.

The PTD901-2015K-A503 is a reliable and cost-effective solution for applications requiring exact resistance control, such as automotive and consumer electronics. The device is also suitable for use in high voltage and current applications, as its precise resistance control and low-power consumption make it a great choice for applications where energy efficiency is a priority.

In summary, rotary potentiometers and rheostats are both types of variable resistors, but they operate on different principles. Rotary potentiometers work by changing the resistance by adjusting an external element, while rheostats work by changing the current through the device by varying the voltage applied. The PTD901-2015K-A503 is an example of a rotary potentiometer, and is suitable for use in applications requiring precise resistance control, such as automotive and consumer electronics.
