What This Socket Cap Covers
The TE Connectivity 2213588-1 is a socket cap from the Nector M series, designed as a protective cover for plug housings that accept socket contacts. It's the part you reach for when a mated connector port sits unused on a washdown line or in a dusty cabinet — the IP67 protection keeps debris and moisture out of the housing cavity when the mating half isn't plugged in. The cap fits housings specified for 5, 6, and 7 positions, so one cap covers a range of circuit counts in the same housing family.
Material and Build for the Environment
Molded from glass-filled Polybutylene Terephthalate (PBT), the cap holds its shape under the heat and chemical exposure common in industrial sensor cabinets and food-processing washdown zones. The glass fill adds stiffness so the cap doesn't deform when you torque it onto the housing — hand-tight should seal it, but the material won't creep if you give it an extra quarter turn. Black color is standard for the series, matching the housings it's meant to cover.
IP67 Seal — What It Means on the Line
The IP67 rating means the cap seals the housing cavity against dust ingress and temporary immersion in water up to 1 meter for 30 minutes. In practice, that's the difference between a sensor port that stays dry after a hose-down and one that fills with water and shorts the next shift. The cap itself doesn't carry contacts — it's strictly a protective cover, so the seal relies on the O-ring in the housing interface, not on a contact seal. Keep the cap on any unused port and you save yourself a mid-shift sensor replacement.
No direct cross-reference or official successor exists in the Nector M series, so this cap is the one to spec for new builds or replacement stock.
