Overview
The AW140-EG-G40A is a single-row pin header from the AW140 series, manufactured by ASSMANN WSW. It features 40 contacts with a 2.54 mm pitch and supports up to 3A current at 250V. Constructed with brass gold-plated contacts and polybutylene terephthalate housing, it utilizes through-hole termination for board-to-board connections. The component operates within a temperature range of -40°C to 105°C.
Feature Summary
- Single-row configuration designed for direct board-to-board interconnection
- Gold-plated brass contacts ensure reliable signal transmission
- Polybutylene terephthalate housing provides structural stability
Applications
- High-density electronic assembly requiring robust interconnects
- Industrial control systems utilizing standard 2.54mm spacing
- Consumer electronics manufacturing with through-hole requirements
Procurement Notes
Verify the specific tail pin length and mating pin height against the official datasheet before ordering, as these dimensions vary significantly across the AW140 series suffixes. Confirm that the 40-contact specification matches the target PCB footprint. Ensure compatibility with mating connectors regarding contact type and plating thickness to prevent mechanical or electrical mismatch during assembly.
Selection Notes
Select this model when a high-pin-count, single-row connector is required for rigid board-to-board applications. The 2.54 mm pitch is standard for general-purpose electronics, while the 3A rating suits moderate power distribution. Consider the specific tail length variant needed for the target stack-up height, as the AW140 series offers multiple lengths for different clearance requirements.
Part Context
This component belongs to the AW140 series, which provides a range of single-row pin headers with consistent 2.54 mm pitch but varying physical dimensions. The series is designed for through-hole mounting on printed circuit boards, offering a standardized interface for connecting daughterboards or modules in compact electronic enclosures.
