- Hall affect sensors - Typically powered by 5 or 12v and having 3 wires (Power,signal, ground), these sensors produce a square wave output, with the voltage sinking whenever any ferrous object is passed. This sensor must be connected to a measurement circuit with a 'pull up resister' fitted. Perfect as wheel speed or cam sensors
- Inductive sensors - Typically having 2 wires (signal positive, ground) these produce a +/- sine wave output with the peak voltages being proportional to the size of ferrous target being passed, the size of clearance gap and also the speed the object passes. Perfect for engine crankshaft speed
