A-BL127DG56-021-GSR1

Overview

The A-BL127DG56-021-GSR1 is a 56-position receptacle connector manufactured by Assmann WSW Components. It features a 0.050 inch (1.27 mm) pitch and is designed for surface mount technology (SMT). The contacts are finished with gold plating to ensure reliable electrical performance. This component is part of the BL series, intended for high-density interconnect applications requiring robust mechanical stability and consistent signal transmission in electronic assemblies.

Feature Summary

Surface mount receptacle design for automated PCB assembly
Gold-plated contacts for enhanced conductivity and corrosion resistance
0.050 inch (1.27 mm) pitch for high-density integration

Applications

High-density board-to-board interconnections
Consumer electronics internal connectivity
Industrial control system modules

Procurement Notes

Verify the specific suffix GSR1 against official datasheets to confirm reel packaging and tape specifications. Ensure compatibility with standard SMT reflow profiles. Confirm that the 56-position configuration matches the target footprint requirements before procurement.

Selection Notes

Select this component when a 56-pin surface mount solution with 1.27mm pitch is required. Consider the gold contact finish for environments demanding long-term reliability. Verify mechanical retention needs and mating connector compatibility prior to integration into the design.

Part Context

This connector belongs to Assmann WSW's BL series, which specializes in board-to-board and cable-to-board solutions. The series is known for providing standardized interconnect options for various industrial and consumer applications, focusing on durability and precise alignment.

Replacement Considerations

Cross-reference with other 56-position, 1.27mm pitch SMT receptacles from Assmann or competitors. Verify pinout consistency and mechanical dimensions to ensure direct replacement without PCB redesign.
