Description:

These Hall-effect devices contain a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a

threshold amplifier, and Schmitt trigger on a single Hallogic® silicon chip. Included on-chip is a band gap voltage regulator

to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21 mA

of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family using power supplies ranging

from 4.5 to 24 volts. Output amplitude is constant at switching frequencies from DC to over 200 kHz.

The Uni-Polar turns on with a (logic level “0”) after a sufficient magnetic field from the south pole of a magnet approached

the symbolized face of the device (Operating Point) and turns off (logic level “1”) after the magnetic field reached a

minimum value. The Bi-Polar latch device turns on (logic level “0”) in the presence of a magnetic south pole and turn off

(logic level “1”) when subjected to a magnetic north pole. Both magnetic poles are necessary for operation for Bi-Polar

devices. This feature makes these sensors ideal for applications in non-contact switching operations, brushless DC motors

and for use with multiple pole magnets.

Applications:



Non-contact reflective object sensor
