The 0.100" (2.54mm) pitch matches the standard MTA-100 header footprint, and the single-row layout keeps the harness narrow for tight wire routing.
Locking Ramp Retention and Closed End Design
The closed-end design blocks the last cavity, preventing a terminal from being inserted into a position that would leave an open circuit at the end of the harness. The red housing colour gives a visual cue on the assembly line that this is the 5-position variant, not the natural-colour 4-position or 17-position versions.
