Magnetic sensors are devices designed to detect and measure magnetic fields or changes in magnetic fields. They are widely used in automation, industrial control, and electronic systems for precise positioning, speed detection, and current sensing. Common types include Hall-effect sensors, magnetoresistive sensors, and reed switches. These sensors enable applications such as motor control, proximity sensing, and navigation systems. Key features include high sensitivity, low power consumption, and robust performance in harsh environments. Typical products in this category include linear and rotary position sensors, magnetic encoders, and current sensors, essential for automation and MRO applications.
