305-084-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-084-520-503 is a standard card edge connector from the 305 series, designed for panel mount and through-hole termination. It features 84 positions with a 0.156-inch (3.96 mm) pitch and dual-edge readout configuration. The contacts are made of copper alloy with gold plating to ensure reliable signal transmission. This female connector supports board thicknesses within specified mechanical limits and operates within a defined temperature range.

Edgeboard Connectors Feature Summary

• Dual-edge contact configuration provides comprehensive electrical connectivity along both edges of the circuit board.
• Gold-plated copper alloy contacts offer corrosion resistance and stable low-resistance performance.
• Panel mount design with through-hole soldering ensures secure mechanical attachment to chassis or backplanes.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing high-density card edge interfaces
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 84-position dual-edge specification. Confirm that the gold plating thickness and copper alloy material meet the application's conductivity requirements. Ensure the panel mounting style aligns with the mechanical design constraints of the target enclosure.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-sided connection is necessary for vertical panel integration. The 3.96 mm pitch accommodates larger trace spacing compared to finer pitches. Verify compatibility with the target PCB thickness and ensure the operating temperature range suits the environmental conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series offers various position counts and configurations to support diverse electronic module designs. The 305 series is widely used in applications demanding durable, high-reliability connections between circuit cards and system backplanes.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 84 positions and 3.96 mm pitch, such as 305-072-520-504 if fewer positions are acceptable. Cross-reference mechanical dimensions and contact plating specifications before substitution.
