Thumbwheel Potentiometers are a versatile set of tools for measuring linear position or rotation. They are used in a wide variety of applications, from industrial motor speed control to audio and video applications. The 3352W-1-502 is a popular version of a thumbwheel potentiometer that is designed specifically for industrial settings. It has a wide range of features, including a mechanical design ideal for harsh industrial environments, and high-accuracy operation.
Design and Construction
The 3352W-1-502 is a standard type thumbwheel potentiometer that uses a conductive disk to measure linear position. The disk has two faces, each of which has a concentric circular pattern of conductive material on it. On one side of the disk is a conductive sleeve and on the other is a non-conductive sleeve. The sleeve is connected to the internal mechanism of the 3352W-1-502 and rotates with the disk when the thumbwheel is rotated. The rotation of the disk lets the internal mechanism calculate the linear position of the wheel.The 3352W-1-502 is constructed from robust materials and features a mechanical design ideal for harsh industrial environments. It is rated for an operating temperature range of -45°C to +85°C and its dust- and water-resistant design meets IEC specifications. The mechanical design ensures that the operating position will not shift over time, even in extreme situations.Electrical Properties
The 3352W-1-502 is designed to provide highly-accurate linear position measurement. The device has a resolution of 5 µm and can be operated at up to 16 different speed settings. The 3352W-1-502 also produces low-temperature drift, as well as low noise and signal noise ratios.The 3352W-1-502 is powered by an external 3.3 VDC supply voltage and features an internal power converter and 3.3 V MOSFET driver. This allows the device to be powered by either AC or DC voltage sources. The integrated MOSFET driver supplies sufficient voltage to both the high- and low-side transistors, resulting in a highly-precise measurement, even in extreme environments.Application Fields and Working Principle
The 3352W-1-502 is a highly versatile thumbwheel potentiometer that is ideal for use in a variety of industrial settings. It can be used to measure linear position in door locks, pumps, and flip switches. It can also measure rotational movement in control systems, motor speed control, and audio/video applications. The mechanical design ensures operation in harsh industrial environments and the device is capable of measuring linear position to an accuracy of 5 µm and rotational speed to an accuracy of 1/16th of a rotation.The 3352W-1-502 uses a conductive disk with concentric circular patterns on each side. One side has a conductive sleeve and the other side has a non-conductive sleeve, both of which are connected to the internal mechanism. This mechanism is powered by an external 3.3 VDC supply, which produces a low-temperature drift and low-noise operation. As the thumbwheel is rotated, the disk rotates with it and the internal mechanism calculates the linear position or rotational speed of the thumbwheel.The specific data is subject to PDF, and the above content is for reference
