3. Overview

The AH-SF12D is an omnipolar low power magnetic proximity switch based on Hall IC for detecting the departure and closing of the object. With AH-SF12D, it needn't distinguish the poles, it only makes the magnet leave or close to the sensor. AH-SF12D has excellent voltage and temperature performance, to ensure that the sensor to stable work in a wide voltage and temperature range, the reverse voltage protection circuit can avoid the reverse voltage damage.

8. AH-SFXXX Series Sensor Function Expansion

While keeping the same shape and location dimensions, other functions can be available depending on the selected Hall IC: With the bipolar latch Hall IC, when using pairs of poles ( one pair or multi-pairs of pole) magnet, the output waveform is a square wave, it can measure the high-speed motor speed and calculate the number

of rotations. With the unipolar conventional Hall IC, when using single magnet, it can measure motor rotation speed, component displacement.

Magnetic proximity sensors provide long sensing ranges that can reliably detect magnetic objects, with entirely new application options opened up due to the smaller magnets.
