Overview
The AW140-EG-Z38C2 is a single-row male header connector from the ASSMANN WSW AW140 series, designed for board-to-board interconnections. It features 38 contacts with a 2.54 mm pitch and supports up to 3A current at 250V. The housing is constructed from PBT material, while brass pins are gold-plated for reliable conductivity. Designed for through-hole mounting, it operates within a temperature range of -40°C to 105°C. Key dimensions include a tail pin length of 3.78mm and a mating pin length of 6.08mm.
Feature Summary
- Gold-plated brass contacts ensure stable electrical performance in board-to-board applications.
- PBT housing provides structural integrity and thermal resistance for reliable operation.
- Straight through-hole design facilitates standard PCB assembly processes.
Applications
- Board-to-board electronic interconnections
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the specific suffix Z38C2 against official manufacturer documentation to confirm exact contact count and physical dimensions. Ensure compatibility with mating socket connectors regarding pitch and housing style. Confirm that the gold plating specification meets the required environmental standards for the intended application environment.
Selection Notes
Select this component when a 38-position straight header is required for high-density board connections. Consider the 2.54 mm pitch constraint and the 3A current rating relative to the circuit load. Verify that the through-hole installation method aligns with the PCB manufacturing capabilities and that the operating temperature range covers the expected environmental conditions.
Part Context
This part belongs to the AW140 series of board connectors manufactured by ASSMANN WSW Components. The series offers various pin counts and configurations for different interconnection needs. This specific model represents a high-pin-count option within the single-row straight header category, suitable for applications requiring robust signal or power transmission between adjacent boards.
Replacement Considerations
Direct substitutes may include other 38-position, 2.54mm pitch headers from ASSMANN WSW or compatible manufacturers. Verify mechanical footprint, pin configuration, and electrical ratings before substitution. Cross-reference datasheets to ensure identical housing material and contact plating specifications.
