AW 127-50/Z-T

Overview

The AW 127-50/Z-T is a 50-position single-row female receptacle connector from the AW 127 series by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and utilizes gold-plated contacts for reliable signal transmission. Designed for through-hole board-to-board mounting, this straight header supports a rated voltage of 100V and a current capacity of 12A. The housing is constructed from polybutylene terephthalate (PBT), ensuring durability across an operating temperature range of -40°C to +105°C. The component meets UL 94 V-0 flammability standards.

Feature Summary

• Single-row configuration with 50 positions for high-density interconnects
• Gold-plated phosphor bronze contacts ensure corrosion resistance and stable conductivity
• Through-hole straight mounting orientation facilitates standard PCB assembly processes
• Polybutylene terephthalate (PBT) housing provides thermal stability and UL 94 V-0 flame retardancy

Applications

• Board-to-board electrical connections in industrial control systems
• Signal routing within telecommunications equipment chassis
• Interconnection modules in consumer electronic device assemblies
• General-purpose circuit board expansion and interface adapters

Procurement Notes

Verify the specific contact plating thickness and material composition against the official manufacturer datasheet prior to integration. Confirm that the through-hole footprint dimensions align precisely with the target printed circuit board layout. Ensure that the selected soldering profile respects the maximum operating temperature limits of the PBT housing to prevent mechanical deformation during assembly.

Selection Notes

Select this model when a 50-position interface is required with a standard 2.54 mm grid spacing. The choice of gold plating over tin is critical for applications demanding long-term oxidation resistance or frequent mating cycles. Consider the straight orientation and through-hole termination method if surface-mount alternatives are unsuitable for the mechanical stress requirements of the installation environment.

Part Context

This component belongs to the AW 127 series, which represents a standardized line of single-row connectors offered by Assmann WSW Components. The series is characterized by its consistent 2.54 mm pitch and robust thermoplastic housing materials designed for general-purpose electronics. Variations within the series typically differ only in the number of positions and terminal plating options, maintaining uniform mechanical and electrical performance characteristics across the product family.
