Current Proximity sensor, design where is the schematic ?

Hi All
Does anyone have the schematic for the original proximity sensor PCB that comes with the Ormerod 2?
I`ve looked all over but can`t seem to find it.... not sure why, maybe it`s a third party "secret" design
As I can gather the sensor has a simple voltage output that connects to an ADC port on the DUET?
I know Dave re-designed this PCB to make use of a modulation technique, but I would like to look at the current design and do my own additions, it`s too expensive to purchase and import the new designed sensor

Hi Dave
Any chance of a PDF version of the schematic, I use Altium Designer, it cannot read the schematics...
Ah.. but looking at the sch in a text viewer I found my answer, TCRT1000, that is the heart of the design
