Product introduction
Three-axis single-chip AMR magnetic sensor
VTC's magnetic sensors are made with anisotropic magnetoresistance (AMR) technology. Compared with magnetic sensors using Hall technology, they have superior characteristics such as high accuracy, low noise, and high temperature stability. . Can be applied to smartphones/tablets, wearable devices (watches, bracelets, virtual reality, augmented reality, true wireless Bluetooth headsets), drones, smart parking lots, smart toys, etc.
