Stress relief contacts (also known as sliding contacts) are designed to simplify connection to the K100 and K100B bead pins. In use, the installer slides the contact over the bead pin and then attaches the tab to the circuit trace.
K110-1-R is designed to connect to a 0.15 mm or larger, microstrip trace on Alumina.
The installation note for K110-1 shows how to make connection using gap welding, wire bonding or soldering.
Anritsu sells a step drill, 01-108 which allows a machinist to create all the required concentric holes for bead installation using only one tool.
