This version is intended for magnetic wheel speed sensors. The signal should be symmetrical around zero volts. Heavy filtering minimises the possibility of interference, resulting in significant variation of the trigger level with frequency.
The Dual Magnetic Converter (DMC) converts magnetic style signals to open collector output signals – a square wave. This makes a typical magnetic sensor behave as a switched or Hall Effect sensor, to make the signals suitable for use with MoTeC ECUs and loggers. This allows magnetic sensors to be used in applications where previously a Hall sensor was required, for example when using the digital inputs on an ECU to measure wheel speed. A single DMC can convert two independent magnetic sensor signals.
