64-Position DIP Header for Ribbon Cable Interconnects
The TE Connectivity AMP-Latch 2-746610-5 is a 64-position DIP header designed for mass-termination of ribbon cable via IDC contacts. It sits in the AMP-Latch series as a full-populated dual-row header, with all 64 positions loaded. The board-side pitch is 0.100" (2.54mm), matching standard DIP socket patterns and prototyping grids, while the cable pitch is 0.050" (1.27mm) — the standard spacing for 64-conductor ribbon cable. This vertical through-hole header is intended for board-to-cable interconnects where a parallel, low-profile connection between a PCB and a ribbon cable assembly is needed, common in internal data and control signal routing within enclosures.
The 64 positions in two rows means a 32-pin-per-row layout, occupying roughly 3.1" of board edge length. The through-hole mounting requires drilled plated holes on that grid — no SMT pads. The vertical orientation places the header perpendicular to the board, with the ribbon cable exiting upward, which suits enclosures where cable routing is above the PCB plane.
The IDC termination accepts 26-28 AWG stranded wire and 26-30 AWG solid wire. The 0.050" (1.27mm) cable pitch means the ribbon cable conductor spacing must match — standard 64-conductor 0.050" pitch ribbon cable is the intended media. The feed-through feature allows the cable to pass through the header body, simplifying daisy-chain or pass-through wiring in harness assemblies.
