Processing patterned after class B or S of MIL-STD-883
0.50” (12.700 mm) lead length
Ceramic Package
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 is not guaranteed to meet all radiation hardness requirements of MIL-STD-883.
