Part No: #53117

OVERVIEW

Three versions of Dual Magnetic Converters (DMCs) are available (A, C and D). DMCs convert magnetic style signals to an open collector output signal (square wave). This makes a typical magnetic sensor behave as a switched or hall effect sensor, thus making the signals suitable for use with ECUs and loggers. A single DMC can convert two independent magnetic sensor signals.

INTENDED USE

This DMCC, is intended as a conditioner for ignition system inputs. Typically used in Drag Racing for measuring ignition timing.

All DMC versions contain trim pots. At manufacture, these are pre-set to specification for the relevant DMC version, they should not be adjusted after purchase.

OPERATION

AC coupled (removes DC offset).

The sensor should be connected in a falling edge configuration and the measuring equipment should be configured to use the negative going edge.

AVAILABLE DMC VERSIONS

Two other versions are available to cater for different purposes and different trigger levels:

DMCA — used for fuel flow sensors that have a very low trigger level.

53111 – DMCA - DUAL MAGNETIC CONVERTOR FOR FUEL FLOW SENSORS

DMCD — used on magnetic wheel speed sensors.

53118 – DMCD - DUAL MAGNETIC CONVERTER FOR WHEEL SPEED SENSORS
