Hi,
Im looking for sub-5mm diameter ultrasonic transducers preferably in
an enclosed form (however I would consider bare ceramics) but I am
struggling to find any distributors that will sell to individuals.
Does anyone know where I can buy some in the UK, preferably online?
I'm looking for frequencies between 40 and 100 khz, less than £5 per
unit, and most importantly, something with a diameter/width of less
than 5mm. This is to satisfy 1/2 wavelength restrictions in air. An
array of transducers would also be considered, but I suspect that they
will be too expensive.

Best regards,
Phil Winder
