305-078-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-501 is a standard card edge connector from the 305 Series, designed for panel mount applications with a vertical orientation. It features 78 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board retention
• Low-profile insulator body construction
• Gold-plated copper alloy contacts for reliable conductivity
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Test and measurement instrument backplanes
• General-purpose electronic assembly interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required board thickness and termination type. Confirm that the thermoplastic polyester housing material meets environmental compliance standards for the target application. Cross-reference the 78-position dual-row layout with mechanical enclosure constraints before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row card edge connector is required for panel-mounted vertical installations. Ensure the mating PCB thickness aligns with the 1.57 mm nominal specification to guarantee proper contact engagement. Consider the green thermoplastic polyester housing for applications requiring standard insulation properties within the specified operating temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are characterized by their durable construction and versatile mounting options. The series offers various position counts and row configurations to accommodate different circuit board densities. The 305-078-555-501 specifically addresses needs for high-density dual-edge connections in industrial and commercial electronics environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but differing termination styles or housing colors. Verify mechanical dimensions and electrical ratings before swapping with other manufacturers' equivalents to ensure fit and function.
