305-064-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-203 is a standard card edge connector designed for dual-sided board insertion. It features 64 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports panel mounting with vertical orientation and solder pin termination. The unit accommodates card thicknesses between 1.37 mm and 1.78 mm, operating within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure double-sided card edge engagement
• Gold-plated copper alloy terminals ensure reliable electrical conductivity
• Vertical panel mount design with solder pin termination for stable installation

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and insulation color specifications. Ensure the selected variant matches the required panel cutout dimensions and thermal rating for the intended operational environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 64-position connection is required with a standard 3.96 mm pitch. Confirm that the host PCB layout supports vertical panel mounting and that the mating card thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and row configurations for general-purpose interconnect applications. The 305 series is characterized by its robust construction and compatibility with standard edgeboard designs used in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-014-521-202 or 305-048-520-203 if different position counts are needed. Verify that any substitute maintains the same 3.96 mm pitch and dual-row configuration to ensure mechanical fit.
