305-068-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-204 is a standard card edge connector featuring 68 positions arranged in a dual-row configuration. It utilizes a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The component is designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C, with a voltage rating of 1800 VACrms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Utilizes gold-plated copper alloy contacts for reliable signal transmission

Edgeboard Connectors Applications

• Panel mount vertical interconnects
• Dual-edge card edge connections
• High-density electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and housing color variations. Confirm panel mount compatibility and solder pin termination requirements prior to integration. Ensure that the selected variant matches the required PCB thickness tolerance of 1.57 mm for proper mechanical engagement.

Edgeboard Connectors Selection Notes

Select this model when a high-position count dual-row interface is required for vertical panel mounting. The 3.96 mm pitch accommodates larger trace widths compared to finer pitches. Verify that the 5 A current rating meets the application's power distribution needs and that the 1800 VACrms insulation rating satisfies safety isolation requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse board interface needs. The 305-068-521-204 specifically provides a 68-position solution within this standardized family, maintaining consistent mechanical dimensions across the series.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts. Verify mechanical footprint compatibility before substituting with other manufacturers' card edge connectors.
