Q1: Are the male tab terminals included with the 1-2112891-4 housing?

A: No. The 1-2112891-4 part number designates the plastic housing and its integrated yellow TPA locks only. The compatible 1.6 mm male tab contacts must be specified and ordered as separate line items.

Q2: Does this automotive housing feature environmental or moisture seals?

A: No. This connector housing is classified as an unsealed (Non-Sealable) variant under its technical specifications and does not contain silicone seals or perimeter gaskets.

Q3: What is the significance of the “Code D” specification for this part number?

A: Code D represents the specific mechanical keying molded into the PBT shell. This housing will only mate with a corresponding Code D female plug to prevent cross-connections in multi-harness architectures.
