The housing is moulded in natural-colour polyamide (PA66 / Nylon 6/6), a common insulation material for internal wiring harnesses where flame rating and mechanical retention are required.
The One Spec That Changes Your BOM
The note "Contacts Not Included" is not a footnote — it is the most actionable line on this listing. This part is the housing only. The 3-position count means it accepts three terminals, one per cavity.
Mating and Polarisation
This is a single-row receptacle. The KK396 series uses a polarisation rib in the housing profile — it will only mate with the corresponding header in one orientation, preventing reverse mating.
