Product details

50-Position CHAMP D-Sub Cover with Strain Relief

The TE Connectivity 552731-1 is a 90° cover cap for the CHAMP series D-Sub connectors, designed specifically for 50-position connectors. This is an accessory, not a connector half — it protects the backshell area of a mated CHAMP D-Sub pair and provides integrated strain relief at the cable exit. The strain relief feature keeps the cable jacket from pulling on the individual contacts inside the connector, which is the most common failure point in a cable assembly that gets flexed or tugged. It ships in Bulk packaging and is ROHS3 compliant.

Compatibility — What It Fits

This cover mates with CHAMP D-Sub connectors in the 50-position size. It is not a universal fit — the 50-position count matches the footprint of the CHAMP 50-pin connector body.
