WTB50PR9SY-1

Overview

The WTB50PR9SY-1 is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It features a right-angle board mount plug configuration with 50 positions arranged in two rows. The component utilizes through-hole termination for copper alloy contacts with gold plating, operating within a temperature range of -65°C to +125°C. Designed with a 2.54 mm pitch and rated for 5 A current and 1 kV voltage, the housing is constructed from Polyphenylene Sulfide (PPS).

Feature Summary

• Right-angle board mount plug design compatible with standard PCB layouts.
• Gold-plated copper alloy pin contacts ensure reliable signal transmission.
• Polyphenylene Sulfide (PPS) housing provides structural integrity and thermal resistance.

Applications

• Military aerospace electronic systems requiring MIL-DTL-55302 compliance.
• High-density printed circuit board interconnections.
• Ruggedized equipment operating in extreme temperature environments.

Procurement Notes

Verify the specific suffix '-1' against official manufacturer documentation to confirm exact polarization, guide set inclusion, and mounting ear specifications. Ensure compatibility with mating receptacles before procurement. Confirm RoHS status and lead times directly with authorized distributors or the manufacturer, as availability may vary.

Selection Notes

Select this part for applications requiring a 50-position right-angle connection with through-hole termination. Verify that the 2.54 mm pitch and dual-row layout fit the available PCB space. Ensure the mating connector matches the pin contact type and polarization code specified in the datasheet.
