305-078-500-207

Edgeboard Connectors Overview

The EDAC 305-078-500-207 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 78 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, providing a thickness of 10.0 µin (0.25 µm). The operating temperature range spans from -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 insulator body constructed from thermoplastic material
• Utilizes solder lug termination type for reliable panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing dual-edge female connectors
• Test and measurement devices needing high-density signal connections

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified partners. Confirm that the specific ordering suffix matches the required pin configuration and termination style. Ensure compliance with RoHS directives if applicable to your assembly process. Request official datasheets to validate electrical ratings against system requirements before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a 78-position dual-row interface is required for 0.062-inch thick PCBs. The 3.96 mm pitch suits applications needing moderate density without excessive board space consumption. Verify that the 5 A current rating meets the power distribution needs of the target circuit. Consider the vertical panel mount style for chassis integration where direct card insertion is necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and 5 A ratings. The 305-078-500-207 variant specifically provides 78 positions, catering to applications requiring higher I/O counts within the same form factor constraints as other models in the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include 305-032-500-207 and 305-040-520-268, though these differ in position count. Cross-series replacements require verification of pitch, row count, and termination type compatibility.
