What This Cap Does in the NECTOR T System
The TE 2363703-1 is a protective cap (cover) from the NECTOR T series, designed to shield unmated NECTOR T connectors from dust, debris, and incidental moisture during transport, storage, or when a connector is left disconnected in the field. It snaps onto the connector face and stays in place until the mating half is ready to engage — a straightforward accessory that keeps the contact cavity clean and the sealing surfaces undamaged. Molded in a blend of Polybutylene Terephthalate (PBT) and Polycarbonate (PC), the cap is black and supplied in bag packaging. The dual-material construction gives it the dimensional stability to hold its fit across temperature swings common in industrial and telecom enclosures, plus the impact resistance to survive handling on a workbench or in a tool kit.
This cap fits the NECTOR T connector family — the same interface geometry that defines the series. If you are building or maintaining a NECTOR T harness and need to protect an unmated receptacle or plug, the 2363703-1 is the correct cover. No special tooling is required; it presses on and pulls off by hand.
