GENERAL INFORMATION
AV vane operated integral magnet posi-
tion sensors are operated by passing a
ferrous vane through the gap between the
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:
Operation by a low cost, easy to
fabricate ferrous vane
Magnet and sensor incorporated in
same rugged package
Sealed construction . . . unaffected by
dust or dirt
0 to 100 kHz operating speed . . . no
minimum speed of operation
On and Off times programmable by
vane dimensioning
Precision mechanical operating

VANE OPERATION
* Operating characteristics of the 4AV are adjusted to produce a .100鹵.010 dimension between the operate
point on one side of the switch, to the release point on the other side. The actuator can be designed to produce a
specific pulse width for timing or sequencing operations.

MOUNTING DIMENSIONS
(For reference only)
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 鈥樷€榖鈥欌€? the
output stops conducting (Sinking
goes High, Sourcing goes Low).
3.
After leading edge reaches 鈥樷€榖鈥欌€?
A. If the vane moves on through the
gap; when the trailing edge
reaches 鈥樷€榙鈥欌€? the output will be
conducting.
B. If direction of vane travel
reverses;
鈥樷€榓鈥欌€? output will be
conducting.
4. For vane movement from right to left,
output is non-conducting when the
leading edge reaches 鈥樷€榗鈥欌€? and is
conducting when the trailing edge
reaches 鈥樷€榓鈥欌€?
