Rotary potentiometers and rheostats are special type of resistors that have one or more adjustable variables. They are designed to be used in a multitude of applications for varying amounts of feedback from the environment. The PTD902-2215K-B104 is an example of such a device. This article will discuss the application field and working principle for this product.

PTD902-2215K-B104 is a type of precision rotary potentiometer designed to be used in audio and automotive applications. The device features an adjustable resistance range of 0 to 200 ohms. It is capable of handling approximately 2000 turns of rotation, offering excellent precision in sensitivity control. It also has 0.1 Watt of power rating and a 4 mm shaft size.

The application field for the PTD902-2215K-B104 rotary potentiometer includes audio, automotive, industrial, and consumer electronics. In audio applications, it is typically used as a volume control mechanism for increasing or decreasing sound output. It can also be used to adjust the balance of left and right channels in sound systems. In automotive applications, the device is often used to control backlighting for displays and illumination for dashboard gauges. It is also used to adjust the power steering or suspension settings.

The working principle of a rotary potentiometer is fairly simple. The device consists of a cylindrical case containing a circular disc with contacts. The device is connected to a circuit and when the rotary switch is turned, it causes the disc to rotate, thus changing the resistance value of the device. The circuit receives feedback from the environment which is mirrored in the resistance value of the potentiometer.

The PTD902-2215K-B104 is a precision rotary potentiometer and rheostat that can be used in a variety of applications, such as audio, automotive, industrial, and consumer electronics. Its adjustable resistance range of 0 to 200 ohms plus its 2000 turns of rotation makes it an ideal choice for precision control of sound systems and other device operations. The device works by changing the resistance value of the device when the rotary switch is turned, thus providing feedback from the environment in the form of resistance.
