A-BL127DG42-021-GSR2

Overview

The Assmann WSW A-BL127DG42-021-GSR2 is a 20-position, single-row female header from the AW 127 series. It features a 2.54 mm pitch and is designed for board-to-board connections via through-hole soldering. The connector utilizes bronze contacts with tin plating and a polybutylene terephthalate (PBT) housing rated UL 94 V-0. It supports a maximum voltage of 100V and current of 12A, operating within a temperature range of -40°C to 105°C.

Feature Summary

Single-row straight female header configuration for direct board-to-board mounting
Through-hole termination method ensures secure mechanical and electrical connection
Polybutylene terephthalate housing provides high thermal stability and flame resistance

Applications

Board-to-board interconnects in industrial control systems
Signal routing in consumer electronic assemblies
Connection interfaces in automotive electronics modules

Procurement Notes

Verify that the specific suffix GSR2 matches the required reel or tape packaging format for automated assembly processes. Confirm that the pin count and pitch align precisely with the mating connector specifications to ensure proper alignment and contact integrity during installation.

Selection Notes

Select this component when a low-profile, single-row solution is required for high-density board stacking. Ensure the application environment remains within the specified -40°C to 105°C operational range and that the 12A current rating per contact is sufficient for the intended signal or power distribution requirements.

Part Context

This part belongs to the AW 127 series of connectors, which are characterized by their compact form factor and reliable performance in space-constrained designs. The series offers various configurations to support different board thicknesses and mating heights while maintaining consistent electrical characteristics across the product line.
