AW 126-27/Z-T

Overview

The AW 126-27/Z-T is a single-row female header connector from the Assmann WSW Components AW 126 series. It features 27 positions with a 2.54 mm (0.100 inch) pitch, designed for board-to-board applications. The component utilizes through-hole termination and is constructed with a polybutylene terephthalate (PBT) housing. Electrical specifications include a current rating of 12 A and a voltage rating of 100 V. The contacts are made of phosphor bronze with gold plating to ensure reliable conductivity. The unit operates within a temperature range of -40°C to +105°C and meets UL 94 V-0 flammability standards.

Feature Summary

• Single-row receptacle design for direct board-to-board interconnection
• Gold-plated phosphor bronze contacts for enhanced signal integrity
• Through-hole mounting configuration for secure PCB attachment
• Polybutylene terephthalate housing providing thermal stability

Applications

• Board-to-board electrical connections in electronic assemblies
• Interfacing between daughterboards and motherboards
• Signal transmission in industrial control systems
• Data acquisition hardware interfaces

Procurement Notes

Verify that the specific part number matches the required contact count and pitch before ordering. Confirm that the gold-plated contact variant is selected if corrosion resistance is critical for the application environment. Ensure compatibility with mating male headers regarding pin layout and mechanical retention. Check RoHS compliance status against project requirements. Validate that the through-hole footprint aligns with the target PCB design constraints.

Selection Notes

Select this component when a 27-position single-row interface is required with high durability. The gold plating offers superior performance over tin variants in harsh environments. Consider the 12 A current rating for power distribution needs alongside signal lines. The PBT material ensures stability at operating temperatures up to 105°C. Verify that the 2.54 mm pitch matches existing system spacing requirements.

Part Context

This connector belongs to the AW 126 series, which provides various position options for single-row applications. It serves as a standard solution for rigid board interconnections where space efficiency and reliable contact are prioritized. The series supports both tin and gold plating options depending on environmental demands.

Replacement Considerations

Direct substitutes must maintain the 27-position count, 2.54 mm pitch, and single-row configuration. Verify that alternative manufacturers offer matching gold-plated phosphor bronze contacts and PBT housings. Ensure identical through-hole termination and UL 94 V-0 certification for regulatory compliance.
