305-056-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-578 is a standard card edge connector from the 305 series, designed for panel mount applications with 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 solder pin termination. It supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Provides a 5A continuous current rating with 1800VACrms dielectric withstand voltage
• Features green thermoplastic insulation housing with half-beam contact type

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connections
• Industrial control systems utilizing polarized card edge interfaces
• High-reliability communication equipment modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating, housing material, and mounting hardware specifications. Confirm that the target application PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 56-position card edge connector with a 3.96 mm pitch is required for panel mounting. Ensure compatibility with polarizing key requirements and verify that the operating environment stays within the -40°C to +105°C temperature limits. Confirm that the mating card edge thickness aligns with the connector's acceptance range.

Edgeboard Connectors Part Context
