KMAH1-25-1-C-S1-HE

Overview

The KMAH1-25-1-C-S1-HE is a circular connector backshell manufactured by TE Connectivity Aerospace, Defense and Marine. It belongs to the KMAH series and is designed for M22x1 threaded interfaces with shell size 25. The component features an aluminum alloy construction with a non-electroplated nickel finish and a silver color. It provides a 180-degree cable exit angle and includes shielding capabilities. The backshell accommodates cables with diameters ranging from 16.30mm to 22.70mm. Its external diameter measures 29.00mm. This part is intended for use with MIL-DTL-38999 Series III and IV connectors.

Feature Summary

• Constructed from aluminum alloy with a non-electroplated nickel finish for durability
• Provides electromagnetic shielding for connected assemblies
• Features a 180-degree cable exit orientation
• Designed for M22x1 threaded coupling environments

Applications

• MIL-DTL-38999 Series III circular connector assemblies
• MIL-DTL-38999 Series IV circular connector assemblies
• Aerospace and defense interconnection systems requiring shielded backshells

Procurement Notes

Verify the specific suffix codes against official TE Connectivity documentation to ensure correct material and environmental ratings. Confirm compatibility with the target MIL-DTL-38999 connector series before procurement. Check for current manufacturing status as availability may vary. Ensure the selected variant matches the required cable diameter range and mounting orientation for the specific application design.

Selection Notes

Select this backshell when a shielded, aluminum alloy solution is required for M22x1 threaded connectors. Ensure the cable diameter falls within the specified 16.30mm to 22.70mm range. Verify that the 180-degree exit angle aligns with the system routing requirements. Confirm that the non-electroplated nickel finish meets the corrosion resistance needs of the operating environment.

Part Context

The KMAH1 series represents a line of circular connector backshells designed for high-reliability applications. These components are engineered to provide strain relief and environmental protection for military-grade circular connectors. The series supports various thread sizes and cable exit angles to accommodate diverse assembly configurations in demanding sectors such as aerospace and defense.

Replacement Considerations

Public sources indicate that the KMAH1-25-1-C-S1-HE is no longer manufactured. Engineers should consult official TE Connectivity substitution guides or contact the manufacturer directly for approved equivalent parts or updated product lines that meet the same mechanical and electrical specifications.
