True Zero-Speed Low-Jitter High Accuracy Gear Tooth Sensor
ATS625LSG
Sensor Description
Figure 2. Device Cross Section. Relative motion of the target is detected
by the dual Hall elements mounted on the Hall IC. This view is from the
side opposite the pins.
Figure 3. This left-to-right (pin 1 to pin 4) direction of target rotation
results in a high output signal when a tooth of the target gear is centered
over the face of the sensor. A right-to-left (pin 4 to pin 1) rotation inverts
the output signal polarity.

Assembly Description
The ATS625LSG true zero-speed gear tooth sensor is a com-
bined Hall IC-magnet configuration that is fully optimized to
provide digital detection of gear tooth edges. This sensor is
integrally 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.
Sensing Technology
The gear tooth sensor contains a single-chip differential Hall
effect sensor IC, a 4-pin leadframe, a samarium cobalt magnet,
and a flat ferrous pole piece. The Hall IC consists of two Hall
elements spaced 2.2 mm apart, and each independently measures
the magnetic gradient created by the passing of a ferrous object.
This is illustrated in figures 2 and 3. The differential output of
the two elements is converted to a digital signal that is processed
to provide the digital output.
Switching Description
After proper power is applied to the component, the sensor is
then capable of providing digital information that is representa-
tive of the profile of a rotating gear, as illustrated in figure 4.
No additional optimization is needed and minimal processing
circuitry is required. This ease of use reduces design time and
incremental assembly costs for most applications.
Figure 4. The magnetic profile reflects the geometry of the target, allowing the device to present an accurate digital output response.
