Bipolar Hall sensor AH3012R (Latch Type)

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.
High reliability and safety with no mechanical contact or spark.
Compliant with EU RoHS and REACH regulations.

Outline

The 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 faces the mark surface and is close (B≤Brp). The output status is latched when the magnet is far away (B=0) and requires an opposite polarity magnetic field to change.

Bipolar Hall sensor AH3012R (Latch Type)-3

Latch Type Hall Sensor AH3012R 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 the “N” pole faces the mark surface and is closed to sensor ( B<Brp ) ,the sensor outputs high level. When the magnet is far away with the sensor (B=0), the output status of the sensor is latched and keeps constant. In order to change the output status, the applied magnetic field must be opposite polarity. The magnet and electric transfer characteristic curve of AH3012R is shown as the figure: 319 NANJING AH ELECTRONIC SCIENCE...
