Overview
The A-BL127DA54-034-GSR1 is a rectangular board-to-board connector manufactured by Assmann WSW Components. It features a 54-position receptacle configuration designed for surface mount assembly with right-angle termination. The connector utilizes a 0.050-inch (1.27mm) pitch to facilitate dense circuit board interconnections. Gold plating is applied to the contact surfaces to ensure reliable signal transmission and corrosion resistance in electronic applications.
Feature Summary
- Right-angle surface mount design for compact PCB integration
- Gold-plated contacts for enhanced conductivity and durability
- 54-position receptacle configuration for high-density connections
Applications
- High-density board-to-board interconnects
- Consumer electronics assemblies
- Industrial control systems
Procurement Notes
Verify the specific ordering suffix GSR1 against the manufacturer's current datasheet to confirm packaging details and tape-and-reel specifications. Ensure the right-angle orientation matches the mechanical layout requirements of the target printed circuit board design prior to procurement.
Selection Notes
Select this component when a 1.27mm pitch board-to-board connection is required in a space-constrained environment. The right-angle form factor allows for vertical stacking or perpendicular mounting relative to the mating board, optimizing three-dimensional assembly space utilization.
Part Context
This part belongs to the A-BL127DA series of rectangular connectors from Assmann WSW Components. The series offers various position counts, including 28 and 54 positions, all sharing the same 1.27mm pitch and surface mount right-angle characteristics for standardized modular design.
Replacement Considerations
Compatible substitutes within the same series include the A-BL127DA28-034-GSR1 for lower pin count requirements. Verify mechanical compatibility and pin alignment before substituting with other manufacturers' 1.27mm pitch right-angle SMD connectors.
