The Phares Electronics MGS03 Gear Tooth Sensor is a peak-detecting device which utilizes special circuitry to provide extremely accurate gear edge detection down to low operating speeds. This sensor can be used in conjunction with a wide variety of gear shapes and sizes.

The technology used for this device is Hall-effect based. The device incorporates a dual-element Hall IC that switches in response to differential magnetic signals created by ferromagnetic targets. As a result, the MGS03 can detect other ferromagnetic targets such as (but not limited to) bolt heads, key stock, flat washers, etc. The MGS03 can also detect magnetic targets.

The MGS03 processing circuitry self-calibrates (normalizes) the internal gain of the sensor to minimize the effect of air gap variations. The peak-detecting filter circuit tolerates magnet and system offsets and has the ability to discriminate relatively fast changes such as those caused by tilt, gear wobble, and eccentricities. This easy-to-integrate solution provides first falling edge detection and stable operation to extremely low rpm.

The MGS03 Gear Tooth Sensor is ideal for use in systems that gather speed and timing information using gear-tooth-based configurations. This device is particularly suited to those applications that require extremely accurate duty cycle control or accurate edge-detection.
