The TE Connectivity 2-747580-2 is a shielded outer ferrule for the DB37 shell size, designed for the AMPLIMITE HD-20, HDE-20, HDP-20, and HDP-22 series. It is the metal wrap that clamps over the cable jacket at the back of the D-sub backshell, completing the shield path from the cable braid to the connector shell. The 37-position count matches the standard DB37 pinout — this is the outer ferrule, not the inner ferrule that grips individual wires, so it is sized for the overall cable bundle diameter of a full 37-contact harness.
Shielded Construction and DB37 Fit
The shielded construction means this ferrule is intended for EMI-sensitive signal paths — think data cables, instrumentation links, or any DB37 run where radiated emissions or susceptibility is a concern. It mates with the matching AMPLIMITE backshell hardware for the HD-20, HDE-20, HDP-20, and HDP-22 families. If you are building a cable assembly for a DB37 male or female connector from those series, this is the outer ferrule that clamps the cable shield to the backshell ground plane.
Sourcing This Part
The bag packaging is standard for this ferrule type; expect it shipped loose in an ESD-safe bag, ready for kitting into your cable assembly.
