305-016-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-016-556-578 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features 16 positions with a 3.96 mm pitch and accepts double-sided card edges. The contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The housing is green thermoplastic, supporting board thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides high dielectric strength with 1800VACrms insulation capability
• Features solder pin termination for reliable panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card connections
• High-voltage interface modules needing robust insulation
• Panel-mounted electronic assemblies with specific thermal requirements

Edgeboard Connectors Procurement Notes

Verify the exact suffix against official EDAC documentation to confirm material and plating specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm that the polarizing key requirements match the system design constraints.

Edgeboard Connectors Selection Notes

Select this component when a 16-position dual-row connector with a 3.96 mm pitch is required. It is suitable for applications demanding high voltage isolation and polarized insertion. Consider the vertical panel mount style and solder pin termination method for mechanical integration.

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 options. The 305-016 variant specifically provides a compact solution for double-sided cards within the specified thermal and electrical ratings.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes. Verify that alternative parts maintain the 3.96 mm pitch and 16-position configuration. Ensure any replacement supports the same polarizing key mechanisms and voltage ratings.
