The TE Connectivity 4-640442-1 is an 11-position MTA-100 IDC receptacle with a 0.100" (2.54mm) pitch — the standard spacing for this series. A locking ramp on the housing secures the mate to the matching MTA-100 header, and the closed end blocks the last cavity to prevent a stray pin from shorting the circuit. The blue housing color is a visual identifier on multi-harness assemblies. This connector is designed for wire-to-board interconnects inside electronic equipment — think power supplies, control panels, and appliance PCBs where the harness is built once and stays mated.
Right-Angle Cable Exit and Locking Ramp — Fit in Tight Spaces
This receptacle mounts free-hanging with the cable exiting at a right angle to the board — a practical choice when the enclosure height is limited and a straight-out cable route would hit the cover. The locking ramp engages with a positive click on the mating header, so the connection stays put under moderate vibration or cable tug.
26 AWG Only — The IDC Slot Is Not Negotiable
The IDC termination is sized for 26 AWG wire. Stick with 26 AWG discrete or ribbon cable for a reliable termination.
