Dual-Channel Quadrature Hall-Effect Bipolar Switch Module for Magnetic Encoder
https://www.electronics-lab.com/dual-channel-quadrature-hall-effect-bipolar-switch-module-magnetic-encoder/
The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch […]
