Overview
The AW140-EG-Z28F is a pin header connector from the AW140 series manufactured by Assmann WSW Components. It features a single row with 28 positions and a 2.54mm (0.100 inch) pitch. Designed for through-hole mounting, this straight connector utilizes gold-plated contacts to ensure reliable signal transmission. The housing is constructed from PBT material, providing durability for board-to-board applications.
Feature Summary
- Single-row configuration for compact circuit board integration
- Gold-plated contacts for enhanced conductivity and corrosion resistance
- Through-hole termination method for secure PCB attachment
Applications
- Board-to-board interconnections
- General electronic equipment internal wiring
- Industrial control system modules
Procurement Notes
Verify the specific contact count and orientation against design requirements before ordering. Confirm that the through-hole mounting style matches the target printed circuit board layout. Ensure compatibility with mating connectors in the same series to maintain proper alignment and electrical continuity during assembly processes.
Selection Notes
Select this component when a straight, single-row header with 28 pins is required. The 2.54mm pitch is standard for many digital interfaces. Consider the mechanical stability provided by through-hole mounting versus surface-mount alternatives. Evaluate the operating temperature range and voltage ratings to ensure suitability for the specific environmental conditions of the end application.
Part Context
This part belongs to the AW140 series, which offers various configurations including different pin counts and angles. Assmann WSW Components specializes in IC sockets and IDC connectors, but this specific model represents their pin header lineup designed for robust PCB connections. The series provides options for both straight and right-angle orientations to accommodate diverse spatial constraints.
Replacement Considerations
Compatible substitutes include other 28-position, 2.54mm pitch pin headers from Assmann WSW or equivalent manufacturers. Ensure the replacement maintains the same single-row structure and through-hole termination type. Verify that the housing material and contact plating specifications match to preserve electrical performance and mechanical fit.
