Amphenol XC/XCL Precision One-Piece Closed Backshells

Introduction

XC/XCL precision one-piece closed backshells are D-sub connector accessories designed to provide a durable, enclosed rear termination area. They are intended for D-sub connector assemblies used in switching or shorting applications where reliable connector protection and cable management are important.

Part Description

The XC/XCL series consists of precision one-piece closed backshells for D-sub connectors. Their closed construction helps protect the connector’s rear contacts and cable termination area from accidental contact, handling damage, and environmental contaminants.

These backshells can support cleaner cable routing while providing a more finished and mechanically robust connector assembly. They are especially suitable for D-sub systems that incorporate switching or shorting functions, helping maintain dependable operation in compact electronic equipment.

Applications

Potential applications include:

• D-sub switching connector assemblies
• Shorting plug and interconnect systems
• Test and measurement equipment
• Industrial control panels
• Data acquisition hardware
• Communications and networking equipment
• Laboratory instrumentation
• Cable harness and custom interconnect assemblies
• Service and maintenance interfaces
• Legacy serial, control, and I/O connections

Industries

Possible industries include:

• Industrial automation
• Aerospace and defense
• Telecommunications
• Test and measurement
• Medical electronics
• Transportation and rail
• Energy and utilities
• Manufacturing equipment
• Research laboratories
• Electronics service and repair

Usage Ideas

1. Protected Test Fixture Connection
   Use an XC/XCL closed backshell on a D-sub connector for a production test fixture, protecting rear terminations during repeated connections and disconnections.

2. Industrial Control Harness
   Integrate the backshell into a D-sub cable assembly for a PLC or machine-control panel to create a more protected and organized I/O connection.

3. Shorting Connector Assembly
   Build a shorting or switching connector assembly for maintenance equipment, using the closed backshell to help shield the rear contact area.

Conclusion

XC/XCL precision one-piece closed backshells provide a practical protective enclosure for D-sub connector assemblies. Their closed design supports improved durability, cable organization, and termination protection, making them well suited to switching, shorting, control, test, and general-purpose interconnect applications.
