305-056-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-568 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 56 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold-plated copper alloy contacts with a solder pin termination type. The insulator body is green thermoplastic, providing an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Low-profile insulator body design for space-constrained applications
• Gold-plated contacts ensure reliable electrical performance
• Vertical panel mount style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Medical device internal connections
• Energy sector instrumentation panels

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, plating thickness, and flange options. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with 56 positions is required. The 3.96 mm pitch suits applications needing higher density than standard .100 inch pitches. Verify that the panel mounting style aligns with the mechanical enclosure design. Check that the 5 A current rating meets the circuit requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305 series is characterized by its thermoplastic insulator and copper alloy contacts. It is widely used in industrial and commercial electronics where reliable vertical board-to-panel connections are necessary.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or flange configurations. Cross-reference with other EDAC series if pitch or mounting style differs. No generic industry equivalents are confirmed without verifying mechanical and electrical parameters.
