Operational Description
Figure 2. Device Cross Section. Motion of the target is detected by the Hall element mounted on the Hall IC. Panel A, the presence of a tooth feature on
the target is distinguished by a high magnetic flux density, B. Panel B, the presence of a valley feature is distinguished by its low magnetic flux density.
Assembly Description
The ATS673 and ATS674 true zero-speed gear tooth sensor
ICs have a Hall IC-rare earth pellet configuration that is fully
optimized to provide digital detection of gear tooth edges. This
device is molded into a plastic body that has been optimized for
size, ease of assembly, and manufacturability. High operating
temperature materials are used in all aspects of construction.
Hall Technology
The devices contain a single-chip Hall effect sensor IC, a 4-pin
leadframe and a specially designed rare-earth pellet. The Hall IC
supports a Hall element that measures the magnetic gradient cre-
ated by the passing of a ferromagnetic object. This is illustrated
in figure 2. The difference in the magnetic gradients created by
teeth and valleys allows the devices to generate a digital output
signal.
Output
After proper power is applied to the devices, they are then
capable of providing digital information that is representative of
the profile of a rotating gear, as illustrated in figure 3. No addi-
tional optimization is needed and minimal processing circuitry is
required. This ease of use reduces design time and incremental
assembly costs for most applications.
Figure 3. The magnetic profile reflects the geometry of the target, allowing the device to present an accurate digital output response.
