Overview
The A-BL127-DG-Z44MR1 is a 44-position receptacle connector from the ASSMANN WSW Components BL series. It features a 1.27 mm (0.050 inch) pitch and utilizes surface mount technology for PCB integration. The connector includes a dual-guide design to ensure precise alignment during assembly. Electrical specifications include a rated current of 1 A and a dielectric withstanding voltage of AC 500 V for one minute. The housing material is PBT reinforced with 30% glass fiber, providing structural stability.
Feature Summary
- Dual-guide receptacle design for accurate board alignment
- Surface mount termination method for automated assembly
- Glass-fiber reinforced PBT housing for mechanical durability
Applications
- High-density electronic circuit board interconnections
- Industrial control system signal routing
- Consumer electronics internal component linking
Procurement Notes
Verify the specific suffix 'Z44MR1' against official manufacturer documentation to confirm pin count and guide configuration. Ensure compatibility with existing PCB footprint designs before procurement. Cross-reference datasheets for thermal resistance ratings if operating in high-temperature environments. Confirm surface finish specifications match soldering process requirements.
Selection Notes
Select this component when a 44-pin surface mount interface with 1.27 mm spacing is required. The dual-guide feature makes it suitable for applications demanding high insertion accuracy. Consider the glass-fiber reinforced housing for environments requiring enhanced mechanical strength compared to standard plastic housings.
Part Context
This part belongs to the ASSMANN WSW BL series, which specializes in high-density connectors. The series offers various pin counts and mounting options. The BL series is designed for reliable performance in compact electronic assemblies where space efficiency and connection integrity are critical priorities.
Replacement Considerations
Direct substitutes must maintain the 44-position count, 1.27 mm pitch, and surface mount orientation. Verify that alternative components support the same dual-guide mechanism and housing material properties to ensure mechanical fit and electrical continuity.
