Overview
The AW 127-39/G-T is a single-row female header connector from the AW 127 series by Assmann WSW Components. It features 39 positions with a 2.54 mm (0.100 inch) pitch, designed for through-hole mounting in a straight orientation. The contacts are gold-plated bronze, providing reliable signal transmission. Rated for 100 V AC and 3 A current, it utilizes PBT housing material compliant with UL 94 V-0 flammability standards. Operating temperature ranges from -40°C to 105°C.
Feature Summary
- Single-row receptacle design with 39 gold-plated contacts for secure board-to-board connections
- Through-hole straight mounting configuration ensuring stable mechanical alignment
- High-temperature resistant PBT housing meeting UL 94 V-0 safety standards
Applications
- Industrial control system interconnections
- Consumer electronics internal circuit boards
- Telecommunications equipment signal routing
Procurement Notes
Verify the specific contact plating specification against official datasheets, as suffix variations may indicate different materials. Confirm that the 39-position count matches the target PCB footprint exactly. Ensure the through-hole straight profile aligns with assembly requirements. Cross-reference the UL certification status for compliance needs.
Selection Notes
Select this component when a high-density single-row interface is required. The 2.54 mm pitch ensures compatibility with standard header pins. Gold plating offers superior corrosion resistance compared to tin variants. Verify that the 3 A current rating suffices for the application's electrical load before finalizing the design.
Part Context
This part belongs to the AW 127 series of rectangular connectors. The series offers various pin counts and plating options. The G suffix typically denotes gold plating, while Z indicates tin. This specific model provides a high-contact-count solution within the standard 2.54 mm spacing family.
Replacement Considerations
AW 127-39/Z-T serves as a direct substitute with identical mechanical dimensions but tin-plated contacts. Verify that the lower cost of tin plating does not compromise environmental durability requirements for the specific deployment scenario.
