Description

The Phares MGS0303 Geartooth Sensors are peak-detecting devices which utilize special circuitry
to provide extremely accurate gear edge detection down to low operating speeds. These sensors
are compatible for use with a wide variety of gear shapes and sizes.

The technology used is Hall-effect based and incorporates a dual-element Hall IC that switches
in response to differential magnetic signals created by ferromagnetic targets. As a result,
the MGS0303 sensors can detect high ferrous (iron) targets such as geartooth wheels,
bolt heads, key stock, etc. They also detect magnetic targets. The omnipolar operation allows
activation with either a north or a south polarity field of sufficient strength.

The MGS0303 sensors switch between logic low (“0”) and logic high (“1”) when
sensing a target of sufficient strength, and are ideal for use in systems that gather speed and
timing information using gear-tooth-based configurations. These sensors are particularly suited
to applications which require extremely accurate duty cycle control or accurate edge-detection.
