The TE Connectivity 520461-1 is a bottom-mount shield designed for the 4-position round SDL connector series. It snaps onto the plug side to provide EMI containment in harness assemblies where the connector is panel-mounted or free-hanging. The round profile matches the SDL connector body, and the bottom orientation means the shield wraps the lower half of the plug — relevant for routing the cable exit away from the shield shell.
Designed for use with TE SDL connectors — the 4-position round plug housing. The shield clips onto the plug body; no separate hardware required. If your assembly uses a different SDL position count (e.g., 6 or 8 positions), the shield profile may not match — verify the plug housing outer dimensions against the shield ID before ordering.
