305-078-521-268

Edgeboard Connectors Overview

The EDAC 305-078-521-268 is a standard card edge connector featuring 78 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts for reliable signal transmission and supports a continuous current rating of 5 A. Designed for panel mount installation, it offers vertical orientation and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction
• Supports dual edge card configurations

Edgeboard Connectors Applications

• High-speed data handling systems
• FPGA configuration modules
• Industrial control system interfaces

Edgeboard Connectors Procurement Notes

Verify the specific position count and row configuration against the official datasheet before procurement. Confirm that the target PCB thickness aligns with the specified 1.57 mm nominal requirement. Ensure the application environment remains within the documented operating temperature limits. Check for any required polarizing key accessories compatible with this series.

Edgeboard Connectors Selection Notes

Select this connector when a high-density interface with 78 positions is required for dual-edge cards. Consider the 3.96 mm pitch for compatibility with existing board layouts. Evaluate the need for polarizing features if precise insertion alignment is critical. Verify that the panel mount style fits the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust thermoplastic polyester housings and gold-plated contacts. It is designed for applications requiring reliable interconnection between circuit boards and backplanes or chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC ordering guide for alternative part numbers within the 305 series that offer different position counts or flange configurations. Ensure any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness acceptance.
