305-078-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-078-520-504 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 78 positions with a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes gold-plated copper alloy contacts with a half-bead termination type for reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring durability in industrial environments.

• Extender board power connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 78-position interface is required for vertical panel integration. The 3.96 mm pitch accommodates standard board layouts while maintaining robust mechanical stability. Consider the 5 A current rating and thermal operating range for suitability in demanding industrial or commercial electronic assemblies.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides engineered solutions for power and signal connectivity between motherboards, daughterboards, and extenders. The series is characterized by quality engineering and standardized dimensions, facilitating widespread adoption in modular electronic systems requiring reliable card edge interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-078-521-204 for potential pinout or packaging differences. Verify that any substitute maintains the same 0.156-inch pitch and 0.062-inch board thickness acceptance to ensure mechanical fit.
