WTB54PR9SY

Overview

The WTB54PR9SY is a rectangular military specification board connector from the AirBorn W Series, manufactured by Molex. It features a right-angle plug configuration with 54 positions arranged in two rows. The component utilizes gold-plated copper alloy pin contacts and a Polyphenylene Sulfide (PPS) housing. Designed for through-hole solder termination, it supports a current rating of 5 A and a voltage rating of 1 kV. The connector operates within a temperature range of -65 C to +125 C and adheres to MIL-DTL-55302 standards.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Right-angle board mount design facilitates dense circuit board layouts
• Gold-plated copper alloy contacts ensure stable signal transmission
• Polyphenylene Sulfide housing provides high thermal stability

Applications
