Overview
The A-BL127DA70-034-GSR1 is a 70-position rectangular connector receptacle manufactured by Assmann WSW Components. It features surface mount, right-angle termination with gold plating and a 0.050-inch (1.27mm) pitch. The component is designed for reliable electrical interconnection in electronic assemblies.
Feature Summary
- Right-angle surface mount design for space-efficient PCB integration
- Gold-plated contacts to ensure signal integrity and corrosion resistance
- 70-position configuration supporting high-density data transmission
Applications
- High-density electronic circuit boards
- Industrial control systems requiring robust interconnects
- Consumer electronics with limited board space
Procurement Notes
Verify the specific ordering suffix GSR1 against the manufacturer's current datasheet to confirm packaging type and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment due to the surface mount right-angle form factor.
Selection Notes
Select this component when a high-pin-count, right-angle interface is required. The 1.27mm pitch balances density with manufacturability. Verify that the PCB footprint matches the mechanical dimensions specified in the official drawing before finalizing the design.
Part Context
This part belongs to Assmann WSW's rectangular connector family, which includes various pin counts and mounting styles. It serves as a standard interconnect solution within their broader portfolio of connectivity components for industrial and consumer applications.
Replacement Considerations
Check for direct substitutes with identical 70-pin count, 1.27mm pitch, and right-angle SMD mounting. Ensure mating connector compatibility and verify that any alternative maintains the same gold plating specification for contact reliability.
