KMAH3-11-1-B-S1-HE

Overview

The KMAH3-11-1-B-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 use with MIL-DTL-38999 Series III and IV connectors. The component features an aluminum alloy housing with a silver finish and utilizes an M22x1 thread specification. It provides a 180-degree cable exit angle and supports shielded applications. The backshell accommodates cable diameters ranging from 16.30mm to 22.70mm, ensuring secure strain relief and environmental sealing for connected cables.

Feature Summary

• Provides mechanical strain relief and environmental protection for attached cables
• Features a 180-degree exit angle for optimized routing in confined spaces
• Constructed from aluminum alloy with a silver finish for durability
• Designed to maintain shielding integrity in electromagnetic interference environments

Applications

• Aerospace communication systems requiring MIL-DTL-38999 compatibility
• Defense radar and electronic warfare equipment installations
• Marine navigation and control system interconnects
• Industrial automation control panels with high-shield requirements

Procurement Notes

Verify that the selected backshell matches the specific shell size and contact arrangement of the associated connector. Confirm that the cable diameter falls within the specified range of 16.30mm to 22.70mm to ensure proper fit. Ensure the M22x1 thread pitch aligns with the mating connector interface. Check for any specific environmental sealing requirements that may necessitate additional gaskets or compounds not included with the standard backshell unit.

Selection Notes

Select this model when a rigid, shielded backshell is required for MIL-DTL-38999 Series III or IV connectors. The M22x1 thread size dictates compatibility with specific shell sizes; verify this against the connector datasheet. Choose this variant over non-shielded options if EMI/RFI protection is critical. Consider the 180-degree exit orientation relative to available panel space and cable routing paths during the design phase.

Part Context

This component is part of the KMAH series of circular connector accessories. It serves as a complementary element to the main connector body, providing structural support and environmental sealing. The series is widely used in harsh environment applications where reliable signal transmission and physical protection are paramount. It replaces older legacy designs with standardized MIL-DTL specifications.
