305-056-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-edge female configuration with 56 positions and a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, it supports board thicknesses between 1.37 mm and 1.78 mm. The housing utilizes thermoplastic insulation, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for secure structural integration
• Dual-edge female contact configuration for non-specified card edges
• Gold-plated copper alloy contacts for enhanced conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific contact plating thickness and housing color variations. Ensure compatibility with target PCB edge thickness specifications before procurement. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor channels to meet regulatory requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-density 56-position connection is required in a vertical orientation. The 3.96 mm pitch accommodates standard board widths while maintaining electrical isolation. Verify that the application environment remains within the specified -40°C to +105°C operational range to prevent thermal degradation of the thermoplastic housing.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, a line of standard card edge connectors known for durability in harsh environments. The series offers various position counts and mounting styles, providing modular solutions for diverse electronic assembly needs. The 305-056 variant specifically addresses mid-range density requirements.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing identical pitch and mounting style. Verify mechanical footprint and pinout alignment against alternative suppliers' offerings to ensure direct interchangeability without redesigning the host PCB.
