Molex has introduced an industrial connector family that exceed IP67 and can be submerged in various fluids. Discrete Devices
Called MX150L, it “supports low-level signals as well as power applications up to 40A”, said the firm. “Customers can choose from wire-to-wire, wire-to-panel and wire-to-board configurations and a wide range of wire styles and insulation thicknesses.”
Applications are expected in commercial vehicles, marine equipment and industrial equipment, particularly industrial power modules.
That said, not all automotive applications are covered.
“While MX150L connectors exceed IP67 requirements and conform to UL 1977, they are not designed for automotive applications with requirements such as USCAR-2, USCAR-25, GMW3191, AK Testing, J2030, Volvo Technology Requirements and Toyota Connector Spec [TCS], warned Molex.
Housings and terminal position assurance [TPA] components are pre-assembled and shipped in one piece
“The integral TPA provides a secondary lock to keep terminals in place and optional connector position assurance [CPA] components prevent accidental disconnection if the connector latch is depressed,” said the firm. To assemble, the appropriate terminal is crimped, inserted, then the TPA is engaged to its locked position “with no additional assembly steps required. Audible and tactile clicks on insertion, extraction and mating facilitate reliable mating and terminal loading and removal.”
The matt seal is a single silicone-based piece with individual wire openings, and a cap to protect, retain the seal as well as provide strain relief to the assembly.
Connections are based on 1.5 and 2.5mm blade-type terminals “which eliminate the need to purchase, handle and crimp individual wire seals and help reduce labour costs”, claimed Molex.
There are tools for high-volume production, low-volume production, and field repairs.
