305-086-500-507

Edgeboard Connectors Overview

The EDAC Inc. 305-086-500-507 is a standard card edge connector receptacle featuring 86 positions with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. Designed for dual-edge card insertion, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and offers a continuous current rating of 5 A. It supports a maximum operating temperature of +105°C and a minimum of -40°C, providing robust performance in demanding electronic environments.

Edgeboard Connectors Feature Summary

• Dual-edge receptacle design accommodates standard .062 inch thick PCBs
• Gold-plated copper alloy contacts provide durable electrical connectivity
• Low-profile insulator body reduces overall assembly height
• Supports between-contact and in-contact polarizing keys for secure alignment

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Computing hardware motherboards and expansion cards
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, insulation color, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the 86-position count and 3.96 mm pitch with system requirements to prevent mechanical mismatch during integration.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count dual-edge interface is required for .062 inch boards. The 5 A current rating suits moderate power distribution needs. Consider the vertical panel mount orientation if space constraints dictate a specific installation angle. Confirm that the gold plating meets corrosion resistance standards for the intended operational environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for their reliability in industrial applications. The series offers various position counts and mounting styles, allowing designers to scale density without changing the fundamental form factor. The 305-086-500-507 specifically addresses high-density needs within this established family framework.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 305 series designation, such as 305-086-500-201 or 305-086-500-202, provided they match the 86-position count and 3.96 mm pitch. Verify that any alternative maintains the dual-edge receptacle configuration and compatible PCB thickness tolerance.
