Q1: Does this model (334721601) come with Connector Position Assurance (CPA)?

A: No, the 334721601 is the version without CPA. If your application requires a CPA (the small red locking tab) for secondary locking security, please contact our team for the corresponding model number.

Q2: What are the advantages of the “Mat-Sealed” technology used in the MX150?

A: The mat-seal design provides a superior IP-rated waterproof barrier by sealing multiple wires through a single silicone mat. This reduces the number of components needed (no individual wire seals required) and makes the connector more compact and easier to assemble.

Q3: Which terminals are compatible with this 16-pin housing?

A: The 334721601 is designed to use Molex MX150 female terminals (typically 33012 or 33001 series). We can provide these terminals in various plating options (Tin, Silver, or Gold) to match your conductivity requirements.
