305-056-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-056-500-578 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 56 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit accepts PCBs with thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, termination type, and insulation color. Ensure compatibility with the target PCB thickness specifications before procurement. Confirm RoHS compliance status through the latest datasheet documentation provided by EDAC Inc.

Edgeboard Connectors Selection Notes

Select this component when a robust 56-position interface is required for high-current applications up to 5 A. The 3.96 mm pitch accommodates standard board layouts while the dual-edge design offers superior mechanical stability compared to single-edge variants. Consider the vertical panel mount requirement for chassis integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which defines a family of card edge connectors characterized by a 0.156-inch pitch. The series includes various position counts and termination options, all sharing common mechanical dimensions and electrical ratings suitable for demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-050-520-578 or 305-054-556-278, provided the position count matches the design requirements. Verify that alternative numbers maintain the same 3.96 mm pitch and dual-edge configuration.
