WTDXA50SSY

Overview

The WTDXA50SSY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a cable mount receptacle featuring 50 positions arranged in 3 rows with a 2.54 mm pitch. The component utilizes crimp termination for 22 AWG wires and includes gold-plated copper alloy socket contacts. Constructed with a Polyphenylene Sulfide (PPS) housing, it supports chassis mounting at a straight angle. Electrical ratings include a current capacity of 5 A, voltage rating of 1 kV, and insulation resistance of 5 GOhms. The unit operates within a temperature range of -65 C to +125 C.

Feature Summary

• Compliant with MIL-C-55302 military specifications for rugged reliability
• High-density interconnect capability via three-row configuration
• Corrosion-resistant gold plating on copper alloy contacts
• Thermally stable PPS housing material

Applications

• Military avionics systems
• Ruggedized electronic enclosures
• Defense communication equipment

Procurement Notes

Verify the specific revision level against the manufacturer's datasheet before procurement. Confirm that the crimp tooling matches the specified contact size. Ensure environmental sealing requirements align with the connector's design limitations. Cross-reference the part number suffixes to confirm exact pinout and orientation compatibility with mating components.

Selection Notes

Select this model when a high-density, three-row interface is required for chassis-mounted applications. The 2.54 mm pitch allows for compact circuit board or panel layouts. Verify that the 5 A current rating meets the system's power distribution needs. Consider the straight mounting style for direct cabling access without angular adapters.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various row counts and termination styles to support diverse wiring harness configurations. The WTDXA50SSY specifically addresses the need for robust, multi-circuit connections in space-constrained military and industrial panels.
