305-078-520-512

Edgeboard Connectors Overview

The EDAC Inc. 305-078-520-512 is a dual-edge female card edge connector from the 305 series, designed for panel and through-hole mounting. It features 78 positions with a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes gold-plated copper alloy contacts with a half-beehive termination type and a thermoplastic polyester insulator body. Operating within a temperature range of -40°C to +105°C, it complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated half-beehive contacts for reliable termination
• Thermoplastic polyester insulator body with low profile design
• Panel mount installation with solder lug termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to ensure compatibility with required flange characteristics and termination styles. Confirm that the target PCB thickness falls within the specified acceptance range of 0.054 to 0.070 inches. Check for updated environmental compliance documentation such as REACH status prior to final component selection.

Edgeboard Connectors Selection Notes

Select this connector when a robust, high-density interface is required for double-sided edge cards. Ensure the mating PCB has a standard 0.062-inch thickness to guarantee proper engagement. Consider the panel mount style and solder lug termination method during mechanical layout planning. Verify that the operating environment remains within the specified thermal limits for long-term reliability.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting options to accommodate different form factors. The 305-078-520-512 variant specifically provides a balance of density and mechanical stability for industrial applications requiring durable electrical connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing identical pitch and row count if alternative mounting styles are needed. Verify mechanical footprint compatibility before substituting with connectors from other manufacturers. Ensure that any replacement maintains the same contact material and plating specifications for equivalent performance.
