307-074-520-207

Edgeboard Connectors Overview

The EDAC Inc. 307-074-520-207 is a standard card edge connector from the 307 series, designed for dual-edge board applications. It features 74 positions with a 3.96mm contact spacing and 5.08mm row spacing. The connector accepts PCBs with a nominal thickness of 1.57mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5A and offers an insulation resistance of 5 GOhms. The thermoplastic polyester housing is green, and the unit operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified dual-edge cards
• Integrated flange features including flush mount capability, top opening, and threaded inserts
• Solder termination type utilizing semi-beehive contact geometry for secure connection

Edgeboard Connectors Applications

• Panel-mounted electronic systems requiring robust card edge interfaces
• Industrial control units utilizing modular circuit board architectures
• Communication equipment employing standardized double-sided PCB modules

Edgeboard Connectors Procurement Notes

Verify specific flange configuration requirements against the datasheet, as this model includes threaded inserts and top openings. Confirm that the target printed circuit board strictly adheres to the 1.57mm nominal thickness specification to ensure proper mechanical engagement. Ensure compatibility with the specified 3.96mm pitch and 5.08mm row spacing before finalizing integration into the assembly design.

Edgeboard Connectors Selection Notes

Select this component when a panel-mount solution with integrated mounting hardware is required for dual-edge boards. The inclusion of threaded inserts simplifies installation compared to models requiring separate fasteners. Consider the 5A current rating and high insulation resistance for reliable signal integrity in demanding operational environments where physical stability is critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 Series, which provides various mounting styles and termination options. While many connectors in this family share identical electrical parameters and pitch specifications, the 307-074-520-207 is distinct due to its specific combination of 74 positions and specialized flange features. Other variants may offer straight or right-angle PCB mounts without the integrated threaded insert capabilities found in this specific receptacle.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 307-074-560-268, which shares the 74-position count and general form factor but differs in flange characteristics. Verify that any alternative maintains the exact 3.96mm pitch and 1.57mm board thickness tolerance to ensure mechanical fit.
