The TE Connectivity Mark II 2-215882-6 is a 26-position IDC receptacle designed for mass-termination to 0.100" pitch ribbon cable. It carries 30.0µin gold-plated female socket contacts across two rows at 0.100" row spacing, giving you a reliable signal path for parallel data or control wiring in a free-hanging, in-line mount. The gray housing includes a feed-through feature for daisy-chaining multiple connectors on the same cable, plus a polarizing key to prevent mismating with the header. This is a workhorse part for building out 26-conductor ribbon cable harnesses where you need a solid, field-serviceable IDC termination.
The feed-through feature lets you run the ribbon cable through the receptacle and continue to another connector, which simplifies daisy-chain wiring in a backplane or card-cage harness.
