What this 16-position IDC receptacle is for
The closed-end design means this receptacle terminates the cable run at this point — there is no pass-through for daisy-chaining to another connector down the line. That is the right choice when the cable ends here and you do not want an unterminated stub on the bus. For a pass-through that lets you continue the cable to another position, you would look at the open-end version of the same MTA-100 receptacle.
Pitch, positions, and the mating half
The locking ramp on this receptacle engages the latch on the header, so confirm the header you are pairing has the matching ramp feature — most standard MTA-100 headers do, but the unshrouded versions may not.
Termination and wire handling
No stripping, no crimping — one pass with the hand tool or press. The 80.0µin (2.03µm) tin plating is a heavy-duty finish for moderate mating-cycle applications; it handles the typical 25-50 cycles of a field-serviceable harness without issue. Tin is the right choice for cost-sensitive, non-corrosive environments — if the connector lives in a humid or chemically aggressive atmosphere, you would step up to gold plating, but that is a different order code in the MTA-100 family.
