WTB26SAD9SY

Overview

The WTB26SAD9SY is a rectangular MIL-spec connector from the AirBorn W Series, manufactured by Molex. It features a straight receptacle design with 26 positions arranged in two rows. The component utilizes through-hole termination for board mounting and includes gold-plated copper alloy socket contacts. Constructed with a polyphenylene sulfide (PPS) housing, it supports a current rating of 5 A and a voltage rating of 1 kV. The unit operates within a temperature range of -65 C to +125 C, maintains an insulation resistance of 5 GOhms, and employs a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Gold-plated copper alloy female contacts ensure stable signal transmission
• Polyphenylene sulfide housing provides thermal stability up to 125 C

Applications

• Military avionics systems requiring high-density interconnects
• Ruggedized electronic equipment operating in extreme temperatures
• Board-to-board connections in defense communication hardware

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact contact configuration and plating specifications. Ensure compatibility with mating plugs regarding orientation and keying. Confirm RoHS compliance status through manufacturer certificates prior to integration into regulated assemblies.

Selection Notes

Select this model for applications demanding strict adherence to MIL-DTL-55302 performance criteria. The 26-position layout suits moderate density requirements where 2.54 mm spacing is optimal. Evaluate thermal management needs given the 125 C maximum operating limit and PPS material properties.
