Product catalog summary

Features

Rated working voltage: 4.5 V to 24 V, with a minimum limit of 3.5 V.
Operating temperature range: -55℃ to 150℃.
Rated output current (sink): 25 mA, maximum output current (sink): 50 mA.
Switch response time: approximately 1μs, operating frequency: DC to 100 kHz.

Outline

The AH512 Hall Sensor outputs a low level when the 'S' pole of a magnet faces the sensor's mark surface and is close (B ≥ Bop). It outputs a high level when the 'N' pole is close (B ≤ BRP). The output status is latched when the magnet is far (B=0), requiring a reverse polarity magnetic field to change the status.

Block Diagram

The AH512 is a bipolar excitation single-ended digital output Hall IC with a latch function. It includes reverse voltage protection, voltage regulators, temperature compensation, and other components to ensure stable operation across a wide voltage and temperature range.

Bipolar Hall sensor AH512 (Latch Type)-3

Latch type Hall Sensor AH512 Pm-iw When the “S” pole of magnet faces the mark surface of the sensor and is closed to sensor ( B > Bop ), the sensor outputs low level; When “N” pole of magnet is face to sensor’s mark surface and clsed to the sensoi( B< Brp ), the sensor outputs high level. When the magnet is far from sensor, (B=0) , the output status is latched and keep constant, in order to change the output status, the reverse polarity magnetic field must be applied on it.
