The TE Connectivity 646274-1 is a Z-PACK hard metric plug housing for male pins. It is a through-hole mounted housing in gray, sold in bulk. Typical use is in high-density backplane and midplane assemblies for telecom, data networking, and industrial equipment where the hard metric standard (IEC 61076-4-101) defines the grid and keying.
Contacts Not Included — Plan Your BOM
This housing ships empty — you must order the mating male pin terminals separately. For a production run, add the correct TE Z-PACK crimp or press-fit contacts to your BOM. The gray colour is standard for this housing variant; it helps identify the plug half on the board or in the harness.
