305-056-556-207

Edgeboard Connectors Overview

The EDAC Inc. model 305-056-556-207 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 56 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It accommodates PCB thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge boards
• Gold-plated half-wave spring contacts for reliable signal transmission
• Panel mount design with flange features including top-open holes and M3 threaded inserts

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge circuit boards
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct contact plating, insulation color, 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 vertical, panel-mount solution is required for dual-edge cards with a 3.96 mm pitch. Ensure the design accommodates the M3 threaded insert mounting style and verify that the operating environment remains within the -40°C to +105°C thermal limits defined by the thermoplastic insulation material.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability connections in demanding environments. The series offers various position counts and mounting configurations, providing standardized interface solutions for industrial and commercial electronic assemblies requiring durable dual-edge board connectivity.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or mounting variations. Cross-reference compatible parts from other manufacturers only if they strictly match the 3.96 mm pitch, dual-row female configuration, and panel-mount mechanical dimensions.
