Overview
The AW140-EG-G28C1 is a 28-position PC pin receptacle from the AW140 series, designed for board-to-board connections. It features a 2.54 mm pitch and supports a current rating of 3A per contact with a voltage rating of 250V AC/DC. The connector utilizes brass contacts plated with gold or tin over 50 microinches, housed in a black PA9T insulator rated UL94 V-0. It employs a through-hole mounting method with straight orientation and an open rack frame type.
Feature Summary
- Straight orientation design for direct board-to-board interface applications
- Open rack frame construction facilitating easy insertion and removal
- High flammability rating insulator material ensuring thermal stability
Applications
- Board-to-board interconnects in electronic assemblies
- Industrial control system circuitry
- Consumer electronics internal connections
Procurement Notes
Verify that the specific ordering suffix matches the required contact plating option, as gold and tin variants exist within this family. Confirm the package style corresponds to the straight through-hole configuration. Ensure the supplier provides documentation confirming the UL94 V-0 rating for the PA9T insulator material. Cross-reference the pin count to ensure compatibility with the target PCB footprint.
Selection Notes
Select this component when a 28-position straight socket is required for rigid board connections. The 2.54 mm pitch aligns with standard DIP spacing requirements. Consider the 3A current rating for power distribution needs. Verify that the open rack design fits within the available vertical clearance of the enclosure. Check if the specific contact plating meets the environmental corrosion resistance requirements of the application.
Part Context
This part belongs to the AW140 series of PC pin receptacles manufactured by Assmann WSW Components. The series offers various pin counts and configurations for board-to-board applications. These connectors are characterized by their robust mechanical design and reliable electrical performance in standard industrial environments.
Replacement Considerations
Direct substitutes may include other 28-pin straight sockets with identical 2.54 mm pitch and through-hole mounting. Verify mechanical dimensions and terminal compatibility before substitution.
