305-064-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-064-556-258 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 64 positions arranged in two rows. The contact spacing is 0.156 inches (3.96 mm), and it accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy with gold plating on the mating area and tin plating on the tails, ensuring reliable electrical performance.

Edgeboard Connectors Feature Summary

• Dual row female configuration for high-density interconnects
• Gold-plated contacts on mating areas for corrosion resistance
• Low profile insulator body design
• Compatible with straddle mount or board edge installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation modules
• Computer peripheral expansion cards

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and termination style. Confirm compatibility with the target PCB thickness of 1.57 mm. Ensure the panel cutout dimensions align with the connector's flange specifications. Check for RoHS compliance requirements if operating in regulated environments. Validate that the dual read-out orientation fits the assembly layout constraints.

Edgeboard Connectors Selection Notes

Select this component when a 64-position dual-row interface is necessary for vertical panel mounting. The 3.96 mm pitch suits applications where space efficiency is balanced with signal density. Consider the gold-plated contacts for environments requiring long-term reliability without oxidation issues. The thermoplastic polyester insulator provides stability across the specified temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-064 variant specifically addresses higher pin count requirements while maintaining the standard 0.156-inch spacing. It is distinct from single-row or different pitch alternatives within the broader product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 64-position dual configurations. Verify that alternative numbers maintain the same 3.96 mm pitch and 1.57 mm board thickness tolerance. Cross-reference flange dimensions to ensure mechanical fit in existing panel enclosures.
