305-054-521-268

Edgeboard Connectors Overview

The EDAC 305-054-521-268 is a standard card edge connector featuring a dual-row configuration with 54 positions. It utilizes a 3.96 mm (0.156 inch) pitch and accepts non-specified dual-edge cards. The contacts are gold-plated copper alloy, providing a 5 A current rating. Designed for panel mount installation in a vertical orientation, it accommodates board thicknesses between 1.37 mm and 1.78 mm. The housing is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating thickness, and mounting style variations. Ensure compatibility with target PCB edge card dimensions and panel cutout requirements before procurement. Cross-reference RoHS compliance status with the latest manufacturer datasheet to meet regulatory standards for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with a 3.96 mm pitch is required for vertical panel mounting. Confirm that the target circuit board thickness falls within the specified 1.37 mm to 1.78 mm range. Verify that the application environment remains within the -40°C to +105°C operational limits and requires a 5 A continuous current capacity per contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers a comprehensive range of card edge connectors. The series supports various position counts and mounting styles, utilizing consistent 3.96 mm spacing. These connectors are engineered for robust mechanical stability and electrical reliability in demanding industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as 305-048-521-268 or 305-056-521-268. Verify dimensional fit and electrical ratings before substitution.
