Overview
The A-BL127-DG-Z56MP1 is a surface mount receptacle connector manufactured by Assmann WSW Components. It features 56 contact positions arranged in a single row with a 0.050-inch (1.27mm) pitch. The connector utilizes bottom entry termination for PCB mounting and employs tin plating on the contacts to ensure reliable electrical conductivity. Designed for high-density applications, this component provides a secure interface for mating with corresponding header pins or cable assemblies.
Feature Summary
- Surface mount technology design for automated PCB assembly
- Bottom entry configuration for compact board integration
- Tin-plated contacts for corrosion resistance and conductivity
Applications
- High-density electronic circuit boards
- Industrial control systems requiring robust interconnects
- Consumer electronics with space-constrained layouts
Procurement Notes
Verify the specific ordering suffix and package type against the manufacturer's current datasheet before finalizing procurement orders. Ensure that the surface mount footprint matches the target PCB design requirements. Confirm compliance with relevant environmental standards such as RoHS if required by the end product specifications. Cross-reference the part number with authorized distributors to guarantee authenticity and availability.
Selection Notes
Select this component when a low-profile, surface-mount solution is required for connecting flat ribbon cables or flexible circuits. The 1.27mm pitch allows for moderate pin density while maintaining manufacturability. Consider the mechanical stability provided by the surface mount design compared to through-hole alternatives. Evaluate the thermal performance during soldering processes to ensure joint integrity without damaging adjacent components.
Part Context
This connector belongs to the BL127 series from Assmann WSW Components, which specializes in IDC and flat cable interconnect solutions. The series is designed for reliable signal transmission in various industrial and commercial applications. The specific model variant indicates surface mount construction with tin plating, distinguishing it from through-hole or gold-plated versions within the same family.
Replacement Considerations
Direct substitutes may include other 56-position, 1.27mm pitch surface mount receptacles from manufacturers like Molex or Samtec. Verify that alternative parts match the exact body dimensions, terminal spacing, and retention mechanism. Ensure the replacement offers compatible mating force and durability ratings for the intended application environment.
