305-068-500-258

Edgeboard Connectors Overview

The EDAC 305-068-500-258 is a standard card edge connector featuring 68 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm (0.140 inch) row pitch. Designed for 1.57 mm nominal thickness printed circuit boards, this vertical panel-mount header employs solder lug termination. The contacts are constructed from copper alloy and gold-plated to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, the unit operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile thermoplastic insulator body for compact integration
• Provides robust electrical isolation with high dielectric strength ratings

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• High-density modular electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm terminal type and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the required polarizing key accessories are included or ordered separately, as they may not be integrated into the base connector assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. The 68-position count supports moderate-to-high density signal routing. Verify that the 5 A current rating aligns with the load requirements of the connected circuitry. Ensure the vertical mounting style fits within the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge headers. The series offers various position counts and row configurations to accommodate different board densities. The 305-068-500-258 variant specifically addresses applications requiring a dual-row layout with a 1.57 mm board thickness tolerance, providing a standardized solution for industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 68-position dual-row layouts and 3.96 mm pitch. Verify mechanical dimensions and termination styles before substitution. Generic equivalents may lack the specific polarizing key acceptance features.
