Digital-output Hall effect swtiches
These components use the Hall Effect, a fundamental principle in physics, to detect the presence of a magnetic field. When a magnetic field is applied or removed, these devices respond by toggling between on and off states, making them ideal for a wide range of applications.
Digital Hall ICs from Ouzhuo are known for their rapid response to magnetic field changes. This makes them suitable for applications requiring real-time data, such as speed detection in vehicles and proximity sensing in devices.
Unipolar
hall effect IC
A unipolar Hall effect switch is a semiconductor device that responds to changes in magnetic fields by producing an electrical output. They response to One Pole of the magnet, S pole or N pole
Bipolar/Latch
hall effect IC
Latch and Bipolar Hall ICs are designed to detect the presence of a magnetic field, N and S pole.They differ in terms of their output behavior, once a Latch Hall IC is triggered by a magnetic field, it remains in its changed state until it is reset or deactivated. While Bipolar Hall IC is not always latch.
OMNIPOLAR
hall effect IC
Omnipolar Hall ICs are designed to respond to the presence of any magnetic field, regardless of its polarity. In other words, they can detect both North and South magnetic poles with equal sensitivity. This characteristic makes them incredibly adaptable for various applications.
Analog-output Hall effect Linear sensor
These components use the Hall Effect, a fundamental principle in physics, to detect the presence of a magnetic field. When a magnetic field is applied or removed, these devices respond by toggling between on and off states, making them ideal for a wide range of applications.
Digital Hall ICs from Ouzhuo are known for their rapid response to magnetic field changes. This makes them suitable for applications requiring real-time data, such as speed detection in vehicles and proximity sensing in devices.
