After hours in google and various websites I'm still unable to determine examples of part names/nos for the bits used to construct SAW touchpanels.

These links here show the basic layout:

4 Transducers (X1, X2, Y1, Y2) and reflector bars are the bits I'm trying to source.

My question is what sort of transducers are these and what kind of reflectors. I just need a point in the right direction.

Thanks

What you are looking for are piezoelectric crystals operating as ultrasonic transducers. But you don't want them already mounted in a holder since you will need to mount them directly to the glass substrate. Reflectors are probably just bits of steel or brass glued directly to the glass surface. Here is a manufacturer of the raw crystals: http://www.bostonpiezooptics.com/?D=1
