What This Socket Cap Does in the Nector M System
The TE Connectivity 2213587-1 is a socket cap accessory in the Nector M series, designed to cap the socket contact side of a mated pair when the plug housing is disconnected. It protects the socket contacts from debris, moisture, and mechanical damage in environments where the connector is unmated during service or storage. The cap carries an IP67 protection rating, meaning it seals against dust ingress and temporary immersion in water when fitted to the plug housing for socket contact. The housing is molded from Polybutylene Terephthalate (PBT) with glass fill — a material choice that resists creep under clamp load and holds dimensional stability across the operating temperature range typical of industrial and outdoor sealed connector applications. The black color is standard for the Nector M series and provides UV resistance for exposed installations.
Fit and Compatibility — Which Housing It Caps
This socket cap is specified for use with the plug housing that accepts socket contacts in the Nector M system. It is not a standalone connector — it is a protective cover that fits over the plug housing when the receptacle half is disconnected. The 3-position count matches the corresponding Nector M plug housing for socket contact, so the cap aligns with the same keying and latch geometry as the mating interface. The IP67 seal is achieved through the cap's interface with the plug housing — the cap itself does not contain a separate gasket; the sealing surface is molded into the PBT housing. For the cap to maintain the IP67 rating, it must be fully seated and latched onto the plug housing.
