Contact SupplierWe are providing a various types of products such as hall effect sensor Hall Effect Sensor is a non-contact magnetic sensor that detects the presence, absence, or magnitude of a magnetic field. It operates based on the Hall Effect, where a voltage (called the Hall voltage) is generated perpendicular to both the current flow and an applied magnetic field in a conductor or semiconductor. When current flows through a semiconductor plate and a magnetic field is applied perpendicular to it, Lorentz forces push the charge carriers to one side, creating a measurable Hall voltage. The strength and polarity of this voltage depend on:
The magnetic field strength (B)
The current (I) flowing through the sensor

The material properties (Hall coefficient)
Hall Voltage (Vₕ) = (B × I) / (q × n × d)
Where q = charge, n = carrier density, d = thickness of sensor material Hall Effect Sensors
