305-078-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-078-520-502 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 78 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure board attachment. It supports a PCB thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C. Rated for 5 A current, it employs a thermoplastic housing and offers 5 GOhms insulation resistance.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edges for robust signal transmission.
• Panel mount installation style ensures stable mechanical fixation within equipment enclosures.
• Gold-plated contacts provide reliable conductivity and corrosion resistance over extended service life.

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications infrastructure hardware
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify that the target application requires a 78-position dual-row interface with a 3.96 mm pitch. Confirm compatibility with the specified 1.57 mm PCB thickness to ensure proper mating engagement. Check that the operating environment falls within the -40°C to +105°C range. Ensure the system voltage and current do not exceed the 5 A rating per contact. Validate that the panel mounting style aligns with the mechanical design constraints of the host assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, double-sided card edge solution is required for panel-mounted configurations. The 3.96 mm pitch distinguishes it from finer-pitch alternatives suitable for dense surface-mount layouts. Consider the thermoplastic housing material for general-purpose durability. Evaluate the vertical orientation against available space constraints within the enclosure. Compare against other 305 series variants if different position counts or termination styles are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for demanding industrial and commercial environments. The series offers various position counts and mounting options while maintaining consistent electrical performance standards. Components in this family typically feature durable thermoplastic housings and gold-plated contacts to ensure long-term reliability in high-cycle applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and mounting styles but different position counts, such as 305-038-520-502 or 305-050-520-578. Verify that any alternative maintains the 3.96 mm pitch and dual-row configuration to preserve mechanical and electrical compatibility with existing designs.
