Unipolar The switch turns to high current consump-
tion with the magnetic south pole on the top
side of the package and turns to low con-
sumption if the magnetic field is removed.
The switch does not respond to the mag-
netic north pole on the top side.
The output turns low with the magnetic
south pole on the top side of the package and
turns high if the magnetic field is removed.
The switch does not respond to the magnetic
north pole on the top side.
Unipolar
Inverted
The switch turns to low current consumption
with the magnetic south pole on the top side
of the package and turns to high consump-
tion if the magnetic field is removed. The
switch does not respond to the magnetic
north pole on the top side.
The output turns high with the magnetic
south pole on the top side of the package and
turns low if the magnetic field is removed.
The switch does not respond to the magnetic
north pole on the top side.
Bipolar (3-wire only) The output turns low with the magnetic
south pole on the top side of the package and
turns high with the magnetic north pole on
the top side. The output state is not defined if
the magnetic field is removed again.
Latching The switch turns to high current consump-
tion with the magnetic south pole on the top
side of the package and turns to low con-
sumption with the magnetic north pole on
the top side. The current consumption does
not change if the magnetic field is removed.
For changing the current consumption, the
opposite magnetic field polarity must be ap-
plied.
The output turns low with the magnetic
south pole on the top side of the package and
turns high with the magnetic north pole on
the top side. The output does not change if
the magnetic field is removed. For changing
the output state, the opposite magnetic field
polarity must be applied.
2-Wire
Switch
The current is monitored and the switch operates as indicated by the
type of switch. Current level is as specified within the data sheet.
3-Wire
Switch
The voltage is monitored and the switch operates as indicated
according to the type of switch.
