The TE Connectivity 2213229-1 is a ring nut from the Nector M series — a cable-retention accessory that threads onto plug and receptacle housings to clamp the cable jacket and take the strain off the internal contacts. It accepts cables with an outer diameter between 11mm and 14mm, and the glass-filled PBT body gives it the stiffness to hold torque without cracking when you cinch it down in the field. Black colour, bulk packaged.
Cable Fit and Compatibility
The 11mm-14mm cable diameter window is the hard constraint — if your cable jacket falls outside that range, this nut won't seat properly and the cable retention won't engage. It's designed for the Nector M series plug and receptacle housings (5, 6, and 7 positions), so it's a direct fit for those bodies. No thread size is listed in the spec, but the Nector M family uses a standard metric thread that matches the housing nut seat — verify against your housing drawing if you're mixing series.
