305-072-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-207 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch with a row spacing of 3.56 mm (0.140 inch). Designed for PCB mount installation, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic polyester housing provides insulation resistance of 5 GOhms. Operating temperature ranges from -40°C to +105°C.

• Gold-plated contact surfaces ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulator body offers high dielectric strength and thermal stability
• Straight PCB mount style facilitates direct vertical integration onto control boards

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module connections
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 207 corresponds to the required plating finish and material specifications for your application environment. Confirm compatibility with the target board thickness of 1.57 mm to ensure proper mechanical retention. Check regional availability as distribution status may vary by location. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 72-position connection is required for thick PCBs up to 1.57 mm. The 3.96 mm pitch suits applications needing robust pin density without excessive miniaturization. Gold plating is essential for environments requiring low contact resistance and long-term durability. Consider the straight mounting orientation for space-constrained vertical layouts.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in handling various board thicknesses and high-current requirements. The 305 series typically features thermoplastic housings and gold-plated contacts, making it suitable for demanding industrial and commercial electronics where reliable connectivity is critical.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series sharing identical position counts and pitch dimensions. Verify that alternative receptacles match the 1.57 mm board thickness tolerance and dual-row configuration. Ensure substitute components maintain equivalent current ratings and operating temperature ranges for functional equivalence.
