GENERAL INFORMATION
AV vane operated integral magnet posi-
tion sensors are operated by passing a
ferrousvanethroughthegapbetweenthe
Hall sensor and the magnet, shunting the
magnetic flux away from the sensor. AVs
can be used as limit switches by oper-
ating with a single large vane; as tachom-
eter sensors by using toothed wheels; or
as synchronizing elements by using
cams or sectors. AV Series have many
features in common such as:
1
Operation by a low cost, easy to
fabricate ferrous vane
1
Magnet and sensor incorporated in
same rugged package
1
Sealed construction . . . unaffected by
dust or dirt
1
0 to 100 kHz operating speed . . . no
minimum speed of operation
1
On and Off times programmable by
vane dimensioning
1
Precision mechanical operating
characteristics
VANE OPERATION
1. With no vane in the gap the output is
conducting (Sinking is Low, Sourcing
is High).
2. Vane movement from left to right.
When leading edge reaches
‘‘
b’’, the
output stops conducting (Sinking
goes High, Sourcing goes Low).
3.
After leading edge reaches ‘‘b’’:
A. If the vane moves on through the
gap; when the trailing edge
reaches
‘‘
d’’, the output will be
conducting.
B. If direction of vane travel
reverses;
‘‘
a’’, output will be
conducting.
4. For vane movement from right to left,
output is non-conducting when the
leading edge reaches
‘‘
c’’, and is
conducting when the trailing edge
reaches
‘‘
a’’.
