Overview
The AW140-EG-G38B is a single-row pin header from the AW140 series, manufactured by ASSMANN WSW. It features 38 contacts with a 2.54 mm pitch and supports a current rating of 3A at 250V. The connector utilizes gold-plated brass terminals housed in PBT plastic. Designed for board-to-board applications, it employs through-hole mounting with straight orientation. Operating temperatures range from -40°C to 105°C.
Feature Summary
- Gold-plated brass terminals ensure reliable electrical conductivity and corrosion resistance.
- PBT housing material provides structural stability and thermal endurance.
- Straight through-hole design facilitates secure PCB integration.
Applications
- Board-to-board interconnections
- General electronic circuit assembly
- Industrial control systems
Procurement Notes
Verify the contact count matches the specific application requirement, as the model number indicates 38 positions. Confirm that the straight orientation and through-hole termination type align with the target PCB layout. Ensure the operating temperature range meets the environmental conditions of the intended deployment scenario before finalizing procurement decisions.
Selection Notes
Select this component when a single-row, unshrouded header with a 2.54 mm pitch is required. The AW140 series offers a balance of mechanical durability and electrical performance suitable for standard industrial environments. Consider the 3A current rating and 250V voltage limit to ensure compliance with system power requirements.
Part Context
This part belongs to the AW140 series of connectors, which are characterized by their robust construction and standardized dimensions. The series includes various contact counts and orientations, allowing for flexible configuration in diverse electronic designs. ASSMANN WSW manufactures these components to meet rigorous quality standards for commercial and industrial electronics.
Replacement Considerations
Compatible substitutes include other 38-position, 2.54mm pitch headers from different manufacturers, provided they match the straight orientation and through-hole mounting specifications. Verify that alternative parts maintain equivalent current ratings and material compositions to ensure functional interchangeability without redesigning the PCB footprint.
