Ceramic Package
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 that allows 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
approaches the symbolized face of the device (operating point) and turns off (logic level “1”) after the magnetic
field reaches a minimum value. The Bi-Polar device turns on (logic level “0”) in the presence of a magnetic south
pole and turns 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.
B and S devices are processed to OPTEK’s military screening program patterned after MIL-STD-883. This
product has passed Radiation Hardness testing up to 350 Krad (si) per MIL-STD-883 method 1019.6 and up to
150 Krad (si) for ELDRS.

Applications:
 Non-contact switching operations
 Brushless DC motors
 Multiple pole magnets
 Non-contact reflective object sensor
 Assembly line automation
 Machine automation
 Machine safety
 End of travel sensor
 Door sensor
