Pancake or flat connectors have an aspect ratio such as to minimize the projection of the cable connector into either a tube or a power supply. This style of termination relies upon a compressed silicone rubber gasket that is capable of providing radial holdoff of at least 150KVDC per inch./Asset/Pancake.jpg
Originally developed for higher voltage industrial x-ray systems, these terminations are increasingly popular for anode grounded tubes for medical use at voltages to 140KVDC./Asset/SHOT-008.JPG
