Overview
The KA1-MV10405M2 is a male header connector from the Harwin Kona series, designed for high-reliability applications. It features a 4-position configuration with an 8.50mm (0.335 inch) pitch. The connector supports a current rating of 60A per contact and operates within a temperature range of -65°C to +150°C. It utilizes through-hole termination with gold-plated beryllium copper contacts housed in a black insulator rated UL94 V-0.
Feature Summary
- High current capacity of 60A per contact for power distribution
- Robust mechanical locking via hex socket screw-lok mechanism
- Wide operating temperature range suitable for harsh environments
- Gold-plated contacts ensure reliable signal and power transmission
Applications
- Industrial control systems requiring high current connections
- Power distribution units in heavy machinery
- Automotive electronics and battery management systems
- Railway signaling and traction equipment
Procurement Notes
Verify that the specific order matches the KA1-MV10405M2 part number to ensure correct pitch and current ratings. Confirm compatibility with mating sockets using the Screw-Lok system. Check insulation material specifications against environmental exposure requirements. Ensure handling procedures protect the gold-plated contacts during installation.
Selection Notes
Select this component when high current carrying capability is critical alongside secure mechanical retention. The 8.50mm pitch distinguishes it from standard board connectors. Consider the through-hole mounting style for robust PCB attachment. Evaluate the thermal performance limits against the application's maximum operating temperature.
Part Context
This part belongs to the Kona series, which focuses on high-reliability interconnects. The series is characterized by large pitch spacing and high current ratings. It serves as a solution for demanding industrial and transportation sectors where vibration resistance and electrical stability are paramount.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Due to the unique 8.50mm pitch and Screw-Lok interface, generic replacements may not provide equivalent mechanical or electrical performance without custom adapter solutions.
