MTA-100 4-Position IDC Receptacle — 3-641238-4
The 0.100" (2.54mm) pitch matches the standard MTA-100 header footprint, making this a direct wire-to-board interconnect for harness assemblies.
Closed End and Locking Ramp
The closed-end design blocks the last position, preventing accidental insertion of a pin or wire beyond the intended circuit count — a detail that matters when the harness is assembled in a fixture and the operator relies on positive stop.
IDC Termination — 24 AWG, Discrete or Ribbon
Cable termination is IDC, accepting 24 AWG wire in either discrete or ribbon format. The insulation displacement contacts pierce the wire insulation in one press operation — no stripping, no crimping.
No official successor or replacement is on record — the part remains in the current MTA-100 catalog.
