AW 126-31/Z-T

Overview

The AW 126-31/Z-T is a single-row female header receptacle connector manufactured by Assmann WSW Components. It features 31 positions with a 2.54 mm (0.100 inch) pitch, designed for board-to-board applications. The connector utilizes through-hole termination and gold-plated contacts to ensure reliable signal transmission. Constructed with a bronze contact material and PBT housing, it supports a maximum current of 12A and operates within a voltage range up to 100V. The unit meets UL 94 V-0 flammability standards and functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Single-row female header design for direct board-to-board interconnection
• Gold-plated contacts on bronze substrate for enhanced conductivity and corrosion resistance
• Through-hole mounting configuration ensuring secure mechanical attachment
• PBT housing material providing structural integrity and UL 94 V-0 flame retardancy

Applications

• Board-to-board electrical interconnections in electronic assemblies
• Signal routing in industrial control systems
• Interface connections in data acquisition hardware
• General-purpose circuit board stacking applications

Procurement Notes

Verify the specific part number AW 126-31/Z-T against official manufacturer documentation to confirm pin count, plating type, and package style. Ensure compatibility with mating male headers regarding pitch and row configuration. Check for RoHS compliance status and moisture sensitivity level requirements relevant to your assembly process before finalizing procurement orders.

Selection Notes

Select this component when a 31-position single-row female connector is required for rigid board-to-board connections. The 2.54 mm pitch is standard for general electronics, while the gold plating offers superior performance in environments where oxidation resistance is critical. Consider the through-hole mounting requirement and thermal operating limits when integrating into the system design.

Part Context

This component belongs to the AW 126 series of connectors from Assmann WSW Components, which specializes in various interconnect solutions. The AW 126 series typically includes single-row headers and sockets available in multiple position counts. This specific model represents a high-density option within that lineup, tailored for applications requiring robust connectivity with standardized spacing dimensions.

Replacement Considerations

Compatible substitutes include other 31-position, 2.54mm pitch single-row female headers from manufacturers such as Samtec or Molex, provided they match the through-hole termination and gold plating specifications. Verify mechanical dimensions and mating interface compatibility before substitution.
