HALL-EFFECT SWITCH
FOR 2-WIRE APPLICATIONS
115 Northeast Cutoff, Box 15036
Worcester, Massachusetts 01615-0036 (508) 853-5000
Suffix “LT”
SENSOR LOCATIONS
OPERATION
The output of these devices (pin 3) switches OFF when the magnetic
field at the Hall sensor exceeds the operate point threshold (B
OP
). When the
magnetic field is reduced to below the release point threshold (B
RP
), the
device output switches ON. The difference in the magnetic operate and
release points is called the hysteresis (B
hys
) of the device. This built-in
hysteresis allows clean switching of the output even in the presence of
external mechanical vibration and electrical noise.
Suffix “UA”
APPLICATIONS INFORMATION
These devices are normally operated in a 2-wire mode, where the supply
terminal and the output terminal are tied together. An external comparator
detects the change in total supply current by the addition (output off, B > B
OP
)
or subtraction (output on, B < B
RP
) of I
OUT
.

Applications Guide”, which can be found in the latest issue of the
