305-072-500-268

Edgeboard Connectors Overview

The EDAC Inc. 305-072-500-268 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 72 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing to accommodate standard PCB layouts. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts plated with gold, it ensures low contact resistance and durability. The unit is rated for 5 A current and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female card edge interface providing 72 connection points
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Vertical panel mount installation style for secure structural integration
• Thermoplastic insulator body designed for high insulation resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge form factors
• Automotive electronics modules needing reliable signal interfaces
• Test and measurement instrumentation hardware

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact mechanical dimensions and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the 3.96 mm pitch aligns with the design layout. Check RoHS compliance status if required by project specifications. Validate supply chain authenticity through authorized distributors.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 72-position connector is required for vertical panel mounting. It is suitable for applications demanding a 5 A current rating and operation up to 105°C. Choose this part over single-row alternatives when higher density is needed within the same footprint. Ensure the mating card edge thickness matches the 1.57 mm specification for proper engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic design requirements. The 305-072-500-268 variant specifically addresses needs for high-density dual-row connections in panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical 72-position dual-row specifications. Verify pin count, pitch, and mounting style match exactly. Cross-reference with manufacturer cross-reference lists for equivalent components from other suppliers.
