What This Shield Bottom Does for an SDL Round Cable Plug
The TE Connectivity 520465-1 is a shield bottom accessory designed for the 8-position round cable plug in the SDL connector family. It is not a standalone connector — it is the metal shield that wraps the underside of the plug body to contain EMI and provide a ground path through the cable braid. Mates with the matching SDL receptacle housing, which is the other half of the round cable interconnect.
