Overview
The KA1-MV10405M1 is a male header connector from the Harwin Kona KA1 series, designed for high-reliability power applications. It features a vertical through-board mounting style with a pitch of 8.50mm (0.335 inches). The connector provides four positions with individually shrouded recessed contacts finished in gold. It supports continuous currents up to 60A per contact and withstands maximum voltages of 3kV. The design ensures durability over 250 mating cycles, utilizing a 6-finger beryllium copper contact system.
Feature Summary
- Individually shrouded recessed contacts ensure secure alignment and protection
- High current capacity of 60A per contact enables efficient power distribution
- Robust construction supports 3kV voltage ratings for demanding environments
Applications
- Industrial control systems requiring high current density
- Power supply modules needing reliable vertical PCB interconnection
- Automotive electronics subject to shock and vibration
Procurement Notes
Verify that the specific part number KA1-MV10405M1 matches the required 8.50mm pitch and 4-position configuration. Confirm that the vertical through-board termination type aligns with the target PCB layout. Ensure that the 60A current rating and 3kV voltage specifications meet the operational requirements of the intended application circuit before finalizing procurement.
Selection Notes
Select this component when high current carrying capability is critical for the design. The 8.50mm pitch allows for substantial conductor spacing, reducing arcing risks. The vertical orientation simplifies board stacking or direct panel connections. Consider the 250-cycle durability limit for applications involving frequent mechanical mating and demating operations during maintenance or testing phases.
Part Context
This connector belongs to the Kona KA1 series, which is engineered for high-reliability power transmission. The series utilizes beryllium copper contacts to maintain conductivity and spring force over time. The KA1-MV10405M1 variant specifically addresses needs for vertical mounting solutions where space efficiency and robust electrical performance are prioritized in industrial and automotive sectors.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
