Overview
The A-BL127-EG-G40MP1 is a 40-position surface mount receptacle connector from the Assmann WSW Components lineup. It features a 1.27mm (0.050 inch) pitch and utilizes gold-plated contacts to ensure reliable signal transmission. Designed for board-to-board applications, this component offers a compact form factor suitable for high-density electronic assemblies.
Feature Summary
- Surface mount technology design for automated PCB assembly
- Gold-plated contact surfaces for enhanced conductivity and corrosion resistance
- Single row configuration with 40 positions
Applications
- High-density board-to-board interconnections
- Consumer electronics internal connections
- Industrial control module interfaces
Procurement Notes
Verify that the specific suffix G40MP1 corresponds to the required gold plating and package variant. Confirm surface mount compatibility with your PCB footprint design. Ensure the 1.27mm pitch matches the mating header specifications to prevent mechanical misalignment during assembly.
Selection Notes
Select this component when a low-profile, surface-mount solution is required for 40-channel interconnects. The 1.27mm pitch allows for dense circuit layouts compared to larger spacing options. Gold plating is preferred for environments requiring long-term reliability and minimal contact resistance.
Part Context
This part belongs to the broader category of rectangular board-to-board connectors manufactured by Assmann WSW. It serves as a critical interface element in modern electronic devices where space constraints necessitate surface-mounted components over traditional through-hole alternatives.
Replacement Considerations
Direct substitutes must match the 40-position count, 1.27mm pitch, and surface mount orientation. Verify pinout compatibility and housing dimensions before replacing with generic equivalents or alternative manufacturer parts.
