Available by special request only:
DIRECT CRANK SENSOR SYSTEM
-   This triggering method has been superceded by the Mini Sensor system.  

Light Speed Engineering, LLC has developed three different devices to send crankshaft position information to the Plasma CD ignition systems.  One method uses the Hall Effect Module which is installed in the accessory case and senses crank shaft position by means of the non-impulse magneto drive gear.  The second mechanism is the Mini Sensor described on the Mini Sensor page located here.  The old style triggering mechanism is the Direct Crank Sensor system described here.

The Direct Crank Sensor triggering mechanism is versatile and will work with most aircraft engines.  

All 6-cylinder engines and all Continental engines must use the Direct Crank Sensor or the Mini Sensor.

The crank sensor circuit board has two completely independent triggering circuits if it is used for dual Plasma CDI applications.  On single installations only the outer set of sensors and associated wiring harness is installed.
