305-068-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-068-555-278 is a standard card edge connector from the 305 series, designed for dual-row board-to-board or backplane interconnections. It features 68 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic insulator provides an insulation resistance of 5 GOhms. Operating within a temperature range of -40°C to +105°C, it utilizes solder lug termination and panel mount installation.

Edgeboard Connectors Feature Summary

• Dual row configuration with 68 positions for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic insulator housing offers stable mechanical support and electrical isolation
• Solder lug termination style facilitates secure panel mounting applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Medical equipment interconnect solutions needing durable connections
• Agricultural technology hardware operating in harsh environments
• General-purpose electronic modules utilizing standard card edge form factors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact termination style and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the 3.96 mm pitch aligns with the design layout. Confirm RoHS compliance status through official documentation before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and gold plating make it suitable for general industrial signals. Consider the solder lug termination if through-panel mounting is preferred over surface mount alternatives within the same series family.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in various electronic assemblies. The series offers multiple position counts and termination options to accommodate different design constraints. The 305-068-555-278 specifically addresses needs for 68-position dual-row connectivity with standardized dimensions.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts such as 305-068-555-208 or 305-068-555-508 for alternative termination styles or plating options. Verify that any substitute maintains the identical 3.96 mm pitch and 68-position count to ensure mechanical fit.
