305-078-555-568

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-568 is a standard card edge connector featuring 78 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. The component employs gold-plated copper alloy contacts with a solder pin termination type. Rated for 5 A continuous current and 1800 VACrms, it operates within a temperature range of -40°C to +105°C. The insulator is constructed from green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design with integrated card extender and guide features
• Accepts between-contact and in-contact polarizing keys for secure positioning
• Straddle mount installation style with flush mounting flange characteristics

Edgeboard Connectors Applications

• High-density electronic module interconnection
• Industrial control system backplane connections
• Telecommunications equipment signal routing

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact contact plating thickness and terminal length specifications. Ensure compatibility with required polarizing key types before procurement. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm operational range to guarantee proper mechanical engagement and electrical reliability.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-row interface is required for straddle-mounted applications. The 3.96 mm pitch accommodates larger trace widths compared to finer pitches. Consider the 5 A current rating and robust insulation resistance for power or high-signal integrity requirements. Verify that the panel-mount orientation aligns with the system chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. These connectors are designed for reliable mating with double-sided edge cards, providing stable mechanical support and electrical continuity in demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-080-555-568 for similar dual-row specifications with different pin counts. Cross-series replacements require careful verification of pitch, board thickness tolerance, and mounting flange dimensions to ensure mechanical fit.
