1438918-1

Overview

The TE Connectivity AMP Connectors part number 1438918-1 is a rectangular D-Sub connector housing, specifically designed for use with high-density interconnect applications. This component serves as the insulating body for a 26-position D-Sub assembly, accommodating both male and female contact configurations depending on the specific mating hardware selected. The housing is engineered to provide robust mechanical support and electrical isolation for the contacts within the shell. It features a standard mounting hole pattern compatible with common D-Sub shells, ensuring secure attachment in panel or chassis environments. The design prioritizes reliable signal transmission integrity in demanding industrial and commercial settings.

Feature Summary

• Provides structural insulation and alignment for 26-position D-Sub contact arrays
• Engineered for secure panel or chassis mounting via standardized screw holes
• Ensures electrical isolation between contacts and external metal shielding

Applications

• Industrial control systems requiring high-density signal routing
• Test and measurement equipment interfaces
• Telecommunications infrastructure assemblies

Procurement Notes

Verify that the specific application requires a 26-position housing configuration before procurement. Confirm compatibility with the intended D-Sub shell type and contact gender (male or female) as the housing alone does not include contacts. Ensure environmental ratings of the associated contacts meet the operational requirements of the final assembly. Cross-reference the manufacturer's current datasheet to confirm material specifications and compliance status relevant to the project.

Selection Notes

Select this housing when a 26-position D-Sub form factor is required for space-constrained designs. Consider the mating interface requirements, such as cable exit direction and strain relief needs, which may dictate the choice of accompanying shell components. Evaluate the dielectric strength and flammability rating of the housing material against regulatory standards applicable to the end product. Ensure the chosen contacts are rated for the expected current and voltage levels to maintain system reliability.

Part Context

This component belongs to the broader family of D-Sub connectors manufactured by TE Connectivity under the AMP brand. These connectors are widely recognized for their durability and standardized geometry across various industries. The 1438918-1 variant specifically addresses the need for a 26-pin configuration, bridging the gap between lower-density 15-pin and higher-density 37-pin options. It is part of a modular ecosystem where housings, shells, and contacts can be mixed and matched to create custom interconnect solutions.

Replacement Considerations

Direct replacements must match the 26-position footprint and mounting hole pattern. Verify pinout compatibility if integrating with existing PCB layouts or cable assemblies. Consult TE Connectivity documentation for any updated versions or superseded part numbers that may offer improved material properties or availability.
