Overview
The A-BL127DG52-021-GSR1 is a surface mount receptacle connector manufactured by Assmann WSW Components. It features 52 positions 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 automated assembly processes due to its surface mount technology construction.
Feature Summary
- Surface mount receptacle design for PCB integration
- Gold-plated contacts for enhanced conductivity
- Standard 1.27mm pitch configuration
Applications
- Board-to-board interconnections
- Cable-to-board connections
- Consumer electronics assemblies
Procurement Notes
Verify the specific ordering suffix GSR1 against the manufacturer's current documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the pin count matches the required 52-position layout for the target application. Cross-reference the RoHS compliance status with the latest datasheet version to meet environmental regulations.
Selection Notes
Select this component when a 52-position surface mount connector with a 1.27mm pitch is required. Consider the gold plating option if high reliability and low contact resistance are critical for the interface. Evaluate the physical footprint constraints on the PCB to ensure compatibility with the surface mount profile.
Part Context
This part belongs to the A-BL127 series of IDC connectors from Assmann WSW Components. The series offers various position counts, including 26 and 52 positions, sharing the same 1.27mm pitch and surface mount form factor. These connectors are typically used in flat cable applications requiring robust electrical connections.
Replacement Considerations
Compatible substitutes include other 52-position, 1.27mm pitch surface mount receptacles from different manufacturers. Verify that alternative parts match the mechanical height, contact material, and termination style before substitution.
