Operated by vane interrupter
–40 to 125 C temperature range
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:

Current sinking output
Smaller size than 2AV
Four pin in-line printed circuit board
terminals or leadwires
Closely controlled differential to
predict pulse width

* Operating characteristics of the 4AV are adjusted to produce a .100±.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.

Vane material:
Cold rolled steel, 1018 or low in carbon (annealed).
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 ‘‘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’’.
