Technical details and manufacturing context for Hall Effect Sensor

Definition
A Hall effect sensor is a key component within voltage and current sensing systems that detects and measures magnetic fields. It operates by producing a voltage difference (the Hall voltage) across an electrical conductor when a magnetic field is applied perpendicular to the current flow. In voltage and current sensor applications, it is commonly used for non-contact current sensing, position detection, speed measurement, and proximity switching, providing isolation and high reliability.
Working Principle
When a current-carrying conductor is placed in a perpendicular magnetic field, a voltage (Hall voltage) is generated across the conductor transverse to both the current and the field. This voltage is proportional to the product of the current and the magnetic field strength. In a sensor, this effect is used to detect the presence, strength, or change of a magnetic field, which can be correlated to parameters like current flow or position.
