305-030-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-030-556-278 is a standard card edge connector featuring 30 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row spacing of 3.56 mm (0.140 inch). Designed for vertical panel mount installation, the connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current at maximum operating temperatures up to +105°C, it provides an insulation resistance of 5 GOhms. The housing is made of green thermoplastic, and termination is achieved via solder pins.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified board types for versatile integration
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Vertical panel mount style ensures secure mechanical fixation within equipment enclosures
• Thermoplastic insulator body offers structural integrity across a wide operational temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Test and measurement equipment utilizing standardized card edge interfaces
• Telecommunications hardware needing high-reliability signal routing
• Automotive electronics assemblies demanding durable connection solutions

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before procurement. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the datasheet for exact dimensional tolerances to prevent installation errors.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm spacing is required for panel mounting. Consider the 5 A current rating and +105°C temperature limit for thermal management planning. Evaluate the gold-plated contact finish for applications requiring long-term reliability without oxidation concerns. Compare against other series members if different position counts or board thicknesses are needed. Ensure the vertical orientation aligns with the system's spatial constraints and cable routing requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which specializes in standard card edge connectors designed for general-purpose electronic applications. The series offers various position counts while maintaining consistent 3.96 mm spacing and panel mount capabilities. Components in this line are engineered for durability and ease of integration into industrial and commercial hardware. The 305-030-556-278 specifically addresses needs for moderate-density connections with reliable electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical spacing but different position counts, such as 305-050-556-278 or 305-012-556-204. Verify that any alternative maintains the 3.96 mm pitch and dual-row configuration. Ensure replacement parts support the same 1.57 mm board thickness and vertical panel mount style. Confirm that electrical ratings and material specifications match the original design requirements.
