A reluctor sensor is like a generator. It is a coil if wire wrapped around an iron core and usually have a magnet at one end. When a steel tooth passes the iron core it effects the magnetic field and creates a voltage at the end of the wire. The signal out of the sensor is like AC voltage sinewave. The shape of the tooth will effect the shape of the wave.
A hall effect sensor is electronic device that gets effected by magnetic field.
In a vane style hall effect sensor has the element on one side of the sensor and the magnet is on the other. They are seperated by an air gap where the tooth passes through. With no tooth in the air gap the element is in one state and the output of the sensor is usually 0 volt. When metal tooth is in the gap the strength of the magnetic field is stronger and the output of the hall element is 5 Volt. The wave is called a square wave. The signal goes from 0 to 5 volt and 5 to 0 Volt very quickly. A hall sensor needs a external power source to work.
There is a little more involved in how a hall sensor output works and some sensors outputs go from hi to low volts when the metal is in the sensor also some sensor dont output a voltage, they require extra components for you to measure the wave.
Generally for a magnetic sensor you need a scope to view the wave correctly but with a hall sensor you can measure the output with a voltmeter.
Yes the UZ uses reluctor style sensors
