It is the cable-end half of the MTA-156 interconnect system, mating with the corresponding 0.156" (3.96mm) pitch pin header. The white housing distinguishes this 24 AWG variant from other wire-gauge versions in the same series, helping harness assemblers grab the right part for the wire size.
Termination and Mounting — Harness Assembly Fit
The free-hanging (in-line) mount means this receptacle sits at the end of a cable bundle, not on a PCB. The feed-through feature allows the cable to pass straight through the connector body rather than terminating at a right angle, simplifying routing in tight enclosures.
Contact Plating and Wire Compatibility
The heavy tin layer is robust for a single insertion into a header and holds up in a controlled environment. Wire gauge is specified for 24 AWG only — the IDC slot geometry is sized for that conductor diameter; using a different gauge risks an unreliable termination.
