Overview
The A-BL127DG72-021-GSR2 is a 72-position receptacle connector manufactured by Assmann WSW Components. It features a 0.050-inch (1.27mm) pitch and utilizes gold plating for contact surfaces. The component is designed for surface mount technology (SMT) installation, ensuring secure attachment to printed circuit boards. This specific part number identifies the standard configuration with the GSR2 suffix indicating the packaging type.
Feature Summary
- High-density 72-pin layout for compact board integration
- Gold-plated contacts for reliable signal transmission
- Surface mount design for automated assembly processes
Applications
- High-pin-count interface connections in electronic assemblies
- Board-to-board interconnect systems requiring dense pin counts
- Industrial equipment internal connectivity solutions
Procurement Notes
Verify the exact part number including the GSR2 suffix to ensure correct packaging specifications. Confirm that the surface mount footprint matches your PCB design requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure compatibility with the mating header or cable assembly before procurement.
Selection Notes
Select this component when a high-density 72-position connection is necessary. The 1.27mm pitch allows for significant I/O density within limited board space. Gold plating offers durability against corrosion compared to tin finishes. Surface mount mounting facilitates efficient production workflows.
Part Context
This connector belongs to the ASSMANN WSW components portfolio, which specializes in IC sockets and IDC connectors for flat cable applications. The company provides system-supplied connectors tailored for industrial and electronic applications. This specific model represents their standard surface mount receptacle offerings.
Replacement Considerations
Direct substitutes must match the 72-position count, 1.27mm pitch, and surface mount form factor. Verify that any alternative maintains identical gold plating specifications and housing material properties. Ensure the replacement supports the same mechanical retention requirements for your assembly.
