Overview
The AW140-EG-G28A is a 28-position through-hole pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm pitch and is designed for board-to-board connections. The connector utilizes brass contacts with gold plating and is housed in polybutylene terephthalate (PBT). It supports a voltage rating of 250V and a current capacity of 3A, operating within a temperature range of -40°C to 105°C.
Feature Summary
- Through-hole mounting design for secure PCB attachment
- Gold-plated brass contacts for reliable signal transmission
- Polybutylene terephthalate housing for thermal stability
Applications
- Board-to-board interconnections
- Electronic circuit assembly
- Industrial control systems
Procurement Notes
Verify the exact part number against manufacturer documentation to ensure compatibility with specific PCB layouts and mating connectors. Confirm that the gold plating and PBT material specifications meet the environmental requirements of the target application. Cross-reference the 2.54 mm pitch and 28-pin configuration with system schematics prior to procurement.
Selection Notes
Select this component when a standard 2.54 mm pitch through-hole header is required for board-to-board applications. Ensure the 3A current rating and 250V voltage limit align with the circuit's electrical demands. Consider the -40°C to 105°C operating temperature range for environmental suitability. Verify mechanical fit within the assembly constraints.
Part Context
This connector belongs to the AW140 series, which includes various pin counts and configurations from Assmann WSW Components. The series is characterized by its use in general electronic applications requiring robust board-to-board connectivity. Similar models in the series differ primarily in the number of positions and specific housing variations while maintaining consistent electrical and mechanical standards.
Replacement Considerations
Compatible substitutes include other 28-position, 2.54 mm pitch through-hole headers from Assmann WSW or other manufacturers, provided they match the contact plating, housing material, and current/voltage ratings. Verify mechanical dimensions and pin alignment before substitution.
