Overview
The A-BL127-DG-Z72D is a 72-position receptacle connector from the Assmann WSW Components A-BL127 series. It features a 1.27 mm (0.050 inch) pitch and utilizes through-hole termination for secure board mounting. The contacts are tin-plated to ensure reliable conductivity and corrosion resistance. Designed as a single-row female socket, it facilitates efficient signal transmission in compact electronic assemblies requiring high-density interconnections.
Feature Summary
- High-density 72-contact configuration with precise 1.27 mm spacing
- Through-hole solder termination for robust mechanical stability
- Tin-plated phosphor bronze contacts for enhanced conductivity
Applications
- Industrial control system interface boards
- Telecommunications equipment backplanes
- Consumer electronics internal connectivity
Procurement Notes
Verify the specific contact plating thickness and material composition against the official datasheet before integration. Confirm that the through-hole pad layout matches the manufacturer's recommended footprint dimensions. Ensure compatibility with standard lead-free soldering profiles to maintain joint integrity during assembly processes.
Selection Notes
Select this component when a high-pin-count, low-pitch connector is required for direct PCB mounting. The tin-plated finish offers a cost-effective solution for general-purpose applications where gold plating is unnecessary. Consider the single-row form factor for space-constrained designs needing extensive I/O channels.
Part Context
This part belongs to the A-BL127 series, characterized by its fine 1.27 mm pitch and single-row receptacle design. It serves as a standard interconnect solution within Assmann WSW's portfolio, bridging the gap between dense circuit layouts and reliable mechanical attachment through traditional through-hole technology.
Replacement Considerations
Cross-reference pin counts and pitch dimensions carefully. Verify that alternative suppliers offer identical tin-plated contact specifications and compatible housing materials to ensure functional equivalence without redesign.
