The TE Dynamic D-3200 1-2291727-1 is a 4-position, 2-row receptacle housing on a 5.08mm pitch — the pitch is wide enough to route 14-18 AWG power wires without crowding the crimp pockets. The 0.300" (7.62mm) row spacing gives the crimp barrels room to seat fully side-by-side, which matters when you're building a harness with larger-gauge wire.
Sizing the Wire and Choosing the Contact
The crimp termination means you strip, crimp, and insert the wire; no soldering or IDC tooling. For a 4-circuit power harness, the 5.08mm pitch supports a per-contact current rating around 15-20 A depending on wire gauge and ambient temperature — the limiting factor is the crimp terminal's own rating, not the housing.
Comparing the 4-Position to the 6-Position Sibling
The closest functional peer in the same Dynamic D-3200 series is the 1-2069882-6, a 6-position receptacle housing with the same 5.08mm pitch, 0.300" row spacing, crimp termination, and free-hanging mount. The only difference that drives a selection decision is the position count: 4 circuits vs 6 circuits. Both are active and use the same crimp contacts.
