The TE Connectivity 1-1903128-7 is a 34-position plug housing from the Dynamic D-1100 series, built on a 2.00mm pitch with two rows spaced 3.30mm apart. It is a panel-mount, snap-in housing designed for crimp termination — you supply the contacts separately. This housing is the male (tab) side of the Dynamic D-1100 wire-to-board or wire-to-wire interconnect system, used in industrial control panels, automation equipment, and automotive body electronics where a compact, high-density power or signal connection is needed.
The 2.00mm pitch packs 34 circuits into a housing that is noticeably narrower than a 0.100-inch-pitch equivalent — useful when board real estate or wire bundle diameter is tight. The snap-in panel mount means the housing locks into a rectangular cutout without hardware; the locking ramp on the mating receptacle (the female side) provides audible feedback when fully seated. Because contacts are not included, you will need to order the correct Dynamic D-1100 tab terminals separately — typically the 1-1703498 series for 20-24 AWG or the 1-1703499 for 16-20 AWG, depending on your current draw.
Mating Half and System Compatibility
The natural counterpart for a 34-position plug is the 34-position receptacle (e.g., TE 1-2333134-5, which is a free-hanging in-line version with a locking ramp). Both halves use the same crimp terminal family — the tab contacts for this plug, the socket contacts for the receptacle. If you are building a harness, the panel-mount plug stays fixed to the enclosure wall; the receptacle wires then plug into it from the cable side.
