Overview
The AW140-EG-G28D is a 28-position single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and is designed for through-hole mounting on printed circuit boards. The component utilizes a straight orientation with an unshrouded housing configuration. Contact surfaces are gold-plated to ensure reliable electrical performance in board-to-board applications.
Feature Summary
- Single-row pin header design for standard board-to-board interconnections
- Through-hole termination method for secure PCB mounting
- Unshrouded housing structure allowing flexible mating options
Applications
- General electronic equipment interconnects
- Industrial control system circuit boards
- Consumer electronics internal connections
Procurement Notes
Verify the specific contact plating thickness and material composition against the official manufacturer datasheet prior to procurement. Confirm that the unshrouded header style aligns with the mechanical constraints of the target assembly. Ensure compatibility with mating socket connectors regarding pitch and row count specifications.
Selection Notes
Select this component when a single-row, unshrouded through-hole header is required for rigid board-to-board connections. The 2.54 mm pitch is standard for general-purpose electronics. Consider the unshrouded design implications for mating alignment and verify that the straight orientation fits within the available vertical clearance of the enclosure or chassis.
Part Context
This part belongs to the AW140 series of connectors, which provides a range of pin counts and configurations for various electronic applications. The series is characterized by its robust construction and standardized 2.54 mm spacing, making it suitable for a wide array of commercial and industrial products requiring reliable signal transmission.
Replacement Considerations
Compatible substitutes include other 28-position, 2.54 mm pitch, single-row through-hole pin headers from manufacturers such as Samtec, Molex, or TE Connectivity. Ensure that any replacement matches the current rating, voltage rating, and physical dimensions to maintain mechanical fit and electrical integrity.
