SecureThread is a high performance Interconnect System from Amphenol CIT. It uses a blind mateable push on interface with threaded coupling nut to avoid any movement of the cable assembly, once the connection is made. The interconnect system is available as solderless direct attach and solderable SSMP types and supports frequencies in the range of DC – 65 GHz with excellent signal integrity.
The solderless system uses a compression mount type connector on cable side and a hollow plastic housing that is mounted on standard SMA connector footprint on board, using screws on bottom side. The board side connector can be moved on the PCB as long as the footprint is there.
SSMP based SecureThread interconnect consists of coaxial cable assembly with female SSMP connector and a threaded coupling nut. There is male SSMP board mount connector on board side, which needs to be soldered. The SecureThread cable assemblies are available as CoreHC to CoreHC type, CoreHC to Precision Connector 3.5 mm, 2.92 mm, 2.4 mm, and 1.85 mm type and Secure SSMP to Secure SSMP, Secure SSMP to Precision Connector 3.5 mm, 2.92 mm, 2.4 mm, and 1.85 mm type configurations.
| Feature | Customer Benefit |
|---|---|
| Wide frequency range of DC – 65 GHz | Covers the frequency range requirements of users, now and future, at a lower overall cost |
| Solder and Solderless options | Enables quick and efficient connection in highly dense applications |
