Component Specifications

Definition
A Hall-effect sensor is a solid-state device that detects magnetic fields and converts them into proportional electrical signals. It operates based on the Hall effect principle, where a voltage difference is generated across an electrical conductor when a magnetic field is applied perpendicular to the current flow. In industrial applications, it's commonly used for current sensing by measuring the magnetic field generated around a current-carrying conductor.
Working Principle
When a current-carrying conductor is placed in a magnetic field perpendicular to the current flow, a voltage (Hall voltage) is generated across the conductor. This voltage is proportional to both the current and magnetic field strength. In current sensing applications, the sensor measures the magnetic field created by the current flow in a nearby conductor.
