306-011-400-178

Edgeboard Connectors Overview

The EDAC 306-011-400-178 is a standard card edge connector receptacle featuring 22 positions with a 3.96 mm (0.156 inch) contact spacing. Designed for single centerline row applications, it accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes cantilever contact types and gold-plated copper alloy terminals to ensure reliable signal transmission. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing structural integrity and insulation.

Edgeboard Connectors Feature Summary

• Cantilever contact design facilitates secure insertion and retention of the card edge.
• Flush mount configuration with top opening and threaded inserts for panel installation.
• Gold-plated contacts on copper alloy substrates enhance conductivity and corrosion resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust expansion board connections
• Communication equipment interface modules
• Medical device internal circuit board interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 22-position count and flush mount style. Confirm the operating temperature range aligns with the application environment. Ensure the PCB thickness specification is compatible with the connector's acceptance criteria before procurement.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, single-row card edge connector is needed for panel-mounted applications. The flush mount feature with threaded inserts is suitable for secure mechanical attachment. Consider the 5 A current rating and thermal limits to ensure compatibility with the system's electrical and environmental requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its .156 inch pitch and versatile mounting options. The 306 series is widely used in general-purpose electronic assemblies where reliable board-to-panel connectivity is essential.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 22-position count, 3.96 mm pitch, and flush mount configuration. Verify that any alternative part maintains the same cantilever contact type and thermal ratings to ensure functional equivalence.
