The TE Connectivity 8-215083-2 is a 12-position IDC plug from the Micro-MaTch series, designed for mass-termination to 28 AWG ribbon cable. The tin-plated male pins are rated for signal-level duty; the feed-through feature lets the cable pass through the connector body for daisy-chain or pass-through wiring in harness assemblies.
This plug terminates via IDC (insulation displacement) — the 28 AWG ribbon cable is pressed onto the bifurcated contacts, which slice through the insulation and grip the conductor without stripping. The free-hanging (in-line) mount means no PCB footprint — it mates directly to a header on the board or another IDC receptacle.
