Q: What makes the new headers unique ?

A: Many modern control units use aluminium die-cast housings, which call for compact, off-the-shelf headers to connect the harness to the PCB inside. The new Heavy Duty Sealed Connector Headers address this with designs suited for die-cast enclosures while maintaining the family’s proven sealing and vibration resistance. They also introduce glued and flanged header concepts that build on the Heavy Duty Sealed Connector Series standard, supporting robust environmental sealing and mechanical strength in demanding vehicle applications.

Q: What contact systems do these headers accept?

A: Heavy Duty Sealed Connector Series headers accept AMP MCP 1.5K, 2.8, 6.3/4.8K, and MCON 1.2 contacts. Depending on contact size, typical max currents range up to 40 A (6.3/4.8K).

Q: How do I achieve IP69K performance?

A: Use flanged tab housings with cover and follow the mounting instructions noted in the Heavy Duty Sealed Connector Series specification; this configuration supports IP69K. Standard sealing is IP67.

Q: Are right angle (90°) headers available?

A: Yes. The new Heavy Duty Sealed Connector Header parts add 90° options alongside 180° vertical styles for tighter enclosures and ECU layouts.

Q: What IP rating do these housings support?

A: Heavy Duty Sealed Connector Housings provide IP67 sealing and can reach IP6K9K when paired with the proper backshell and mounting per instructions.
