Description:
Unipolar hall switch circuit is the magnetic induction sensor, unipolar work. It is suitable for rectangular or bar magnets sensing work. It is the magnetic induction input, output is a digital voltage signal. It consists of the voltage regulator, hall voltage generator, differential amplifiers, schmidt triggers and the output of an open collector.
Working temperature range for -40 to 150 degrees.
