It is built from a zinc alloy with a nickel-over-copper plating — standard for EMI shielding in industrial and telecom cable assemblies where radiated emissions need to be contained. The backshell includes the assembly hardware and a strain relief clamp, so you are not sourcing those as separate line items on the BOM. ## What the 26 Positions and 180° Exit Mean for the Build 26 positions is the key fit number — it matches the shell size of a standard 26-contact.050-pitch D-sub connector. The two-piece construction lets you install the backshell after the cable is terminated to the D-sub, then close the halves over the cable and tighten the hardware. ## Shielding and Plating — Nickel over Copper The nickel-over-copper plating on the zinc die-cast shell provides a conductive surface that bonds to the D-sub connector's metal shell when the backshell is installed. This continuity is what makes the shield effective — without it, the cable braid termination point would be isolated from the connector ground. The spring lock feature helps maintain consistent metal-to-metal contact between the backshell halves and the D-sub shell over repeated mating cycles. ## Included Hardware and Strain Relief The backshell ships with the assembly hardware and a strain relief clamp. The strain relief clamps onto the round cable jacket after the backshell is closed, taking the mechanical load off the solder or crimp terminations inside the D-sub connector. In a harness that gets handled or routed through a cabinet, that strain relief is what keeps the connections from fatiguing at the solder cups.","metaTitle":"TE 749608-2 AMPLIMITE .050 III Backshell, 26 Pos, Shielded","metaDescription":"TE 749608-2 AMPLIMITE .050 III two-piece shielded backshell, 26 positions, 180° cable exit.
