Overview
The A-BL127DG66-021-GSR2 is a board-mounted receptacle connector manufactured by Assmann WSW Components. It features a 66-position configuration designed for surface mount technology (SMT) applications. The connector utilizes a 0.050 inch (1.27 mm) pitch spacing between contacts to accommodate high-density circuit layouts. The contact surfaces are finished with gold plating to ensure reliable signal transmission and corrosion resistance over time.
Feature Summary
- Surface mount receptacle design for automated PCB assembly
- Gold-plated contacts for enhanced conductivity and durability
- Standard 1.27mm pitch spacing for dense interconnection
Applications
- High-density electronic device interconnects
- Industrial control system boards
- Consumer electronics internal connections
Procurement Notes
Verify the specific part number suffix against the manufacturer's official documentation to confirm exact pin count, termination style, and packaging specifications. Ensure compatibility with standard SMT reflow profiles and check for any RoHS compliance declarations required for your manufacturing process before placing orders.
Selection Notes
Select this component when a 66-position surface mount interface is required on a printed circuit board. The 1.27mm pitch allows for compact designs while maintaining sufficient spacing for standard manufacturing tolerances. Consider the gold finish if long-term reliability in varying environmental conditions is a priority.
Part Context
This connector belongs to the ASSMANN WSW components lineup of board-to-board or cable-to-board interconnect solutions. The company specializes in providing standardized and customized connectivity products for various industrial and consumer applications, focusing on precision engineering and reliable performance.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitute part numbers. Ensure that any replacement maintains the same 66-position count, 1.27mm pitch, and surface mount footprint to guarantee mechanical fit and electrical continuity without redesigning the PCB.
