MTA-156 IDC Receptacle for Discrete or Ribbon Cable Harnesses
The TE Connectivity MTA-156 3-644468-5 is a 5-position, single-row IDC receptacle designed for mass-termination of 24 AWG discrete or ribbon cable. The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, giving a compact wire-to-board interconnect for cost-sensitive harness builds.
IDC Termination — Wire Gauge and Cable Fit
This receptacle terminates 24 AWG wire via insulation displacement contacts (IDC). The feed-through feature allows daisy-chaining multiple receptacles along a continuous cable run, common in ribbon cable harnesses for control or signal distribution.
Mating and Retention — Locking Ramp and Polarizing Key
The polarizing key — a raised rib on one side of the housing — aligns with a corresponding slot on the header, ensuring the connector cannot be inserted backward. This is a field-service-friendly feature: the key prevents damage from forced mis-mating and speeds up harness assembly on the line.
