1、 Product Overview
WOA-A series magnetic induction rotation angle position sensor is a non-contact encoder used to measure the rotation position of the
motor. The magnetic induction rotation angle position sensor product adopts the anisotropic magnetoresistance (AMR) sensor independently developed by Mirang Technology, and adds signal conditioning and algorithms to calculate the angle.
