305-072-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-208 is a standard card edge connector receptacle featuring 72 positions arranged in a dual row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and a 0.140-inch (3.56 mm) row spacing. The component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts plated with gold, it supports a continuous current rating of 5 A. The housing is made from green thermoplastic polyester, providing insulation resistance of 5 GOhms. Designed for PCB mount applications, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female connector design accepting 0.062 inch nominal thickness PCBs
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Green thermoplastic polyester insulator body for structural integrity
• Accepts between-contact and in-contact polarizing keys for secure alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Communication equipment utilizing standard card edge interfaces
• Automotive electronics assemblies needing high reliability connectors
• Medical device hardware requiring stable electrical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct pin count, plating specification, and mounting style. Confirm that the required polarizing key compatibility matches the system design requirements. Cross-reference the thermal rating and current capacity with the application load to prevent operational failure. Ensure the PCB thickness tolerance aligns with the 0.062-inch nominal specification for proper insertion force and retention.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for 0.062-inch thick circuit boards. The 0.156-inch pitch suits general-purpose digital and analog signal routing. Consider the 5A current rating for power distribution needs within the connector limits. The straight mounting style fits panel or chassis integration where vertical clearance is constrained. Verify environmental operating temperatures against the -40°C to +105°C 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 row configurations to accommodate diverse board sizes. The 305 series is characterized by its low-profile insulator body and consistent 0.156-inch contact spacing. It provides a standardized solution for connecting edge-mounted cards to host systems in industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-072-520-208 and 305-072-555-512, provided they match the 72-position dual-row requirement and 0.156-inch pitch specifications. Verify mechanical dimensions and terminal type before substitution.
