AVs can be used as limit switches by operating with a single large vane; as tachometer 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 AV MECHANICAL CHARACTERISTICS Series Left Operate a Mag.

The actuator can be designed to produce a specific pulse width for timing or sequencing operations. Thickness Min. Window Min.

MOUNTING DIMENSIONS (For reference only) BLOCK DIAGRAM Leadwire PC Board 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’’.
