Overview
The A-BL127DA66-034-GSR1 is a surface mount receptacle connector manufactured by Assmann WSW Components. It features 66 positions with a 0.050-inch (1.27mm) pitch. The connector utilizes right-angle termination for PCB integration and employs gold plating on the contact surfaces to ensure reliable signal transmission.
Feature Summary
- Surface mount design for automated assembly
- Right-angle termination configuration
- Gold-plated contacts for conductivity
Applications
- High-density electronic circuit boards
- Industrial control systems
- Communication equipment interfaces
Procurement Notes
Verify the specific ordering suffix GSR1 against the manufacturer's current datasheet to confirm exact packaging and reel specifications. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance documentation prior to procurement.
Selection Notes
Select this component when a high-pin-count, low-profile interconnect solution is required for space-constrained designs. The right-angle form factor facilitates vertical stacking or edge connections, while the 1.27mm pitch balances density and manufacturability.
Part Context
This part belongs to Assmann WSW's line of IDC and board-to-board connectors. It serves as a critical interface element in complex assemblies where reliable electrical connection between rigid PCBs and flexible ribbon cables or other modules is essential.
Replacement Considerations
Cross-reference pinout and mechanical dimensions with alternative suppliers. Verify that substitute parts maintain the same 1.27mm pitch and right-angle orientation to ensure physical fit and electrical continuity without redesigning the footprint.
