The WDD35D4 series angle sensor adopts hard aluminum alloy material to make the shell, and uses conductive plastic as the resistance material. Conductive plastic is a functional polymer material that is mixed with resin and conductive material and processed in a plastic processing method. Mainly used in electronics, integrated circuit packaging, electromagnetic wave shielding and other fields. The conductive plastics of this series of potentiometers have been molded and laser trimmed and fine-tuned to ensure the corresponding high precision. The precious metal brush torrent device, stainless steel high-speed bearings and other components ensure the high quality and high performance of the product, and have a long mechanical life.

Excellent performance with high resolution, smooth rotation and low dynamic noise.


The product has a compact structure and a high-quality aluminum alloy shell, which is suitable for large quantity angle measurement in most engineering sites, automated production lines or laboratory occasions.
