The TH12A is a Hall Effect Latch sensor manufactured by Topstek Inc. This sensor is designed to respond to magnetic fields and provide a digital output signal indicating the presence or absence of a magnetic field. The latching characteristic means that once the magnetic field exceeds a certain threshold, the output will remain in that state even if the magnetic field is removed, until a reverse magnetic field is applied.
