Thumbwheel Potentiometers are widely used in a variety of applications for providing precise, reliable, and repeatable resistance control and voltage divider capabilities. Among these is the versatile 3352P-1-103 model, which features a durable and efficient construction. In this article, we\'ll take a look at the application field and working principle of the 3352P-1-103.

The 3352P-1-103 thumbwheel potentiometer provides a potentiometric division and provides a multiplied reference that corresponds to an angular displacement of the shaft. The 3352 model is available with a full scale deflection (FSD) resistance of 10Ω to 20MΩ, ensuring a wide range of application areas. This model is particularly suitable for data entry in a wide range of applications, including data processing, automation, data acquisition, remote control, instrumentation, medical equipment, industrial control, and light control.

The 3352P-1-103 is offered with either a single-axis or a dual-axis shaft configuration. The single-axis version offers a single-turn, 5-bit thumbwheel knob with a range of resistance from 0 to 1024 counts. The dual-axis version consists of two independent 10-bit axial thumbwheels, each with a range of 0 to 1023 counts. The linearity of this device is ±1%, while the contact resistance is less than 50 mΩ.

The working principle of the 3352P-1-103 is based on the concept and construction of a potentiometric resistor divider. In this type of resistor divider, the resistance elements are arranged linearly from the high potential (retaining rail) to the low potential (output rail). A wiper arm moves along the resistor elements and taps a resistance determined by the desired output voltage across a given load. As the thumbwheel potentiometer knob is rotated, the wiper arm moves across the resistor elements, generating an output voltage that is a function of the relative position of the wiper arm.

The 3352P-1-103 features a double layer slug core in the potentiometer element, which ensures stable operation and repeatable performance. The device also includes an encapsulated seal for excellent dust and moisture resistance, and it is tested to 5000 cycles in order to guarantee long operation life and reliability. The device is also low cost and cost-effective in comparison to other similar devices.

In summary, the 3352P-1-103 thumbwheel potentiometer is a versatile and reliable device ideal for a wide range of applications, from data entry to automation and instrumentation. The device features a durable construction, excellent performance, and a low cost. With a wide range of FSD resistance, as well as a double layer slug core and encapsulated seal for dust and moisture resistance, this device is an excellent choice for many applications.
