Overview
The A-BL127DG48-021-GSR2 is a surface-mount receptacle connector manufactured by Assmann WSW Components. It features a 48-position configuration with a 0.050-inch (1.27mm) pitch. The connector utilizes gold plating for the contact surfaces to ensure reliable signal transmission and corrosion resistance. Designed for board-to-board or cable-to-board applications, it supports standard PCB mounting processes.
Feature Summary
- Surface mount receptacle design for direct PCB integration
- Gold-plated contacts for enhanced conductivity and durability
- Standard 1.27mm pitch spacing for compatible pin headers
Applications
- Board-to-board interconnections in electronic assemblies
- Cable-to-board connections using mating harnesses
- Industrial control system interface modules
Procurement Notes
Verify that the specific order quantity matches the manufacturer's minimum packaging requirements. Confirm the exact reel or tube count before finalizing the purchase order. Ensure the shipping address aligns with the distributor's regional capabilities. Check for any specific handling instructions related to ESD-sensitive components during transit. Validate the part number suffix against the required orientation and locking mechanism specifications.
Selection Notes
Select this component when a high-density 48-position connection is required on a single row. Ensure the mating header matches the 1.27mm pitch specification exactly. Consider the mechanical retention needs of the application to determine if additional locking features are necessary. Verify the available vertical height clearance on the PCB layout to accommodate the connector profile.
Part Context
This part belongs to the A-BL127DG series of connectors from Assmann WSW Components. The series offers various position counts ranging from small arrays to high-density configurations. All variants share the same 1.27mm pitch and surface-mount footprint characteristics, differing primarily in the number of contacts and specific housing dimensions.
Replacement Considerations
Direct substitutes include other 48-position, 1.27mm pitch surface-mount receptacles from manufacturers such as Samtec or Molex. Ensure the replacement part maintains identical pin spacing, contact plating material, and mounting hole alignment. Verify that the mating header compatibility remains unchanged.
