Working Principle
The working principle of the 3352W-1-202LF thumbwheel potentiometer is based on the ohmic voltage divider circuit. It consists of a voltage divider formed by two resistors, a variable resistor and a fixed one, and a wiper connected to an external circuit that can measure the potential difference between the two resistors. As the thumbwheel is turned, the position of the wiper changes, changing the ratio of the two resistors in the voltage divider circuit and resulting in a changing potential difference.The 3352W-1-202LF is a 4-wire potentiometer with a third, metal-shielded contact that acts as a ground. This provides additional shielding against noise and interference, increasing its accuracy. The device also features a low-noise wiper contact and a molded plastic body and knobs for increased durability and user comfort.Conclusion
The 3352W-1-202LF thumbwheel potentiometer is a small, cost-effective, and user-friendly device that can be used in a wide range of applications such as automotive, aerospace, medical, industrial, and consumer electronics. Its working principle is based on the ohmic voltage divider circuit, consisting of two resistors and a wiper. Thanks to its low-noise wiper contact, additional shielding, and molded plastic body, the 3352W-1-202LF is highly accurate and durable.
