305-068-520-268

Edgeboard Connectors Overview

The EDAC Inc. model 305-068-520-268 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 68 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum board thickness of 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness to ensure reliable signal transmission. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing insulation resistance of 5 GOhms. This panel-mount header uses solder pin termination for secure PCB attachment.

• Thermoplastic polyester housing with green color coding
• Solder pin termination for robust panel mounting

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Agricultural technology equipment interfaces
• General-purpose electronic module headers

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact physical dimensions and material specifications. Ensure compatibility with the target card edge thickness range of 1.37 mm to 1.78 mm. Confirm that the 3.96 mm pitch aligns with the printed circuit board layout requirements. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required. The 68-position count suits applications needing moderate I/O density. Consider the vertical panel mount style and solder pin termination for fixed installations. The green thermoplastic body and gold contacts offer durability in standard operating environments up to 105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and spacing options. The 305 series is characterized by its use of thermoplastic polyester insulators and gold-plated contacts. It is designed for reliable performance in industrial and commercial electronic assemblies requiring durable card-to-board connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-052-520-201 or 305-070-556-568 for different position counts. Verify that any substitute maintains the same 3.96 mm pitch and dual-edge female contact type. Ensure mechanical fit and electrical ratings match the original design requirements.
