A polarizing key on the housing prevents incorrect insertion against the mating header, which saves rework time on the harness assembly line.
The Contacts Trap — Order Separately
For the Dynamic D-2100 series, the compatible male crimp contacts are typically the TE 1-1318114-x family (tin or gold plating depending on your mating cycle and corrosion requirements). Confirm the wire gauge range on the terminal datasheet — the housing accepts the contact body, not the wire directly.
Mating Half and Assembly Fit
The free-hanging (in-line) mounting type means this housing is the cable-side half; it does not mount to a panel or PCB.
It is ROHS3 Compliant.
