Amphenol M85049/48-2-3F, Steel D-sub Connector Backshell, 25 Way, Strain Relief

The Amphenol M85049/48-2-3F is a rugged one-piece backshell designed for 25-way D-Sub connectors (shell size B) to provide reliable cable termination and mechanical protection in harsh industrial, transportation or defence environments. Constructed from steel with a cadmium-yellow chromate finish, it supports a 180° cable exit and integrates strain relief to secure the cable exit point and maintain connector integrity.

Salient Features and Benefits of Choosing the Amphenol Steel D-sub Connector Backshell

• Designed for 25-way D-Sub shell size B configurations.
• Steel construction with cadmium-yellow chromate plating for durability and corrosion resistance.
• 180° cable exit angle for streamlined cable routing in tight assemblies.
• Built-in strain relief to reduce mechanical stress on cable termination.
• Compliant with MIL-DTL-M85049 series specification for high-reliability applications.

Engineered for Robust Interconnect Protection

The M85049/48-2-3F backshell ensures consistent performance by protecting the D-Sub interface from mechanical strain, vibration, and environmental factors. The steel body provides structural integrity while the cadmium-yellow finish offers enhanced corrosion resistance, making it a trusted solution for assemblies where reliability and compliance with legacy military/transportation standards matter.

Wide Application Range

• Cable termination for 25-way D-Sub connectors in control panels and rack systems.
• Strain-relief protection for industrial automation wiring looms.
• Ruggedised connector assemblies for transportation, military or aerospace vehicles.
• Replacement backshells in legacy systems.
• Environments exposed to vibration, shock, or temperature extremes.
