Overview
The A-BL127-DG-G44MR1 is a female header connector from the AW 127 series manufactured by Assmann WSW Components. It features 44 positions with a 2.54 mm pitch, designed for board-to-board connections via through-hole soldering. The contacts are made of phosphor bronze with square shapes, housed in polyamide (PA6T) or nylon 6T insulation filled with glass fiber. Rated for 1A per contact and UL 94 V-0 flammability.
Feature Summary
- Square contact shape for secure mating
- Glass-filled polyamide insulation housing
- Through-hole mounting configuration
Applications
- Board-to-board interconnects
- Industrial control modules
- Consumer electronics assemblies
Procurement Notes
Verify the specific insulation material variant, as datasheets indicate polyamide (PA6T) or nylon 6T options. Confirm that the 1A rating applies per contact rather than total current. Ensure compatibility with standard 2.54 mm male headers. Check for RoHS compliance status if required for your region.
Selection Notes
Select this component when a high-density 44-position vertical header is needed. The glass-filled PA6T offers thermal stability. Verify that the through-hole footprint matches your PCB design constraints. Consider the square contact profile for reliable signal transmission in dense arrays.
Part Context
This part belongs to the AW 127 series, a line of standard connectors from Assmann WSW. The series typically includes various pin counts and orientations. The G44 suffix likely denotes the 44-position count within this standardized family of board-to-board solutions.
Replacement Considerations
Generic 2.54mm pitch 44-position female headers may serve as substitutes. Ensure the replacement maintains the same square contact shape and through-hole termination style. Verify that the insulating material meets the same UL 94 V-0 rating.
