Description
A pack of 5 A3144 series Hall Effect Sensor Switches, perfect for detecting magnetic fields in electronics projects, automation systems, and Arduino based applications.
These sensors integrate a Hall voltage generator, amplifier, Schmitt trigger, and an open collector output for reliable magnetic detection with excellent noise immunity.
When a magnetic field exceeds the operating threshold (Bop), the output switches LOW.
The state remains until the magnetic field falls below the release point (Brp), switching the output HIGH.
