TYPICAL OPERATING CHARACTERISTICS
SUPPLY CURRENT
The A3064LKA is a versatile high-precision differential
sensing device that can be used in a wide range of applications.
Careful choice of the sensor IC, target material and shape,
magnet material and shape, and assembly techniques enables
large working air gaps and high switch-point accuracy over the
system operating temperature range.
Magnet Biasing.
To sense moving non-magnetized
ferrous targets, these devices must be back biased by mounting
the unbranded side on a small permanent magnet. Either
magnetic pole (north or south) can be used.
The devices can be used without a back-biasing magnet.
For example, the sensor can be used to detect a rotating ring
magnet such as those found in brushless dc motors or in speed
sensing applications.
Sensor Operation.
These sensor ICs each contain two
integrated Hall transducers (E1 and E2) that are used to sense a
magnetic field differential across the face of the IC (see Sensor
Location drawing). Referring to the Typical Transfer Charac-
teristic (Figure 1), the trigger switches the output off (output
