345-078-555-878

Edgeboard Connectors Overview

The EDAC Inc. 345-078-555-878 is a dual-sided card edge connector featuring 78 positions with a 0.100-inch (2.54mm) pitch. It utilizes female cantilever contacts made of copper alloy, finished with 10.0µin gold plating. Designed for through-hole termination, the unit supports board thicknesses between 0.054 and 0.070 inches. The housing is constructed from green thermoplastic polyester, providing a robust interface for high-density signal transmission.

Edgeboard Connectors Feature Summary

• Dual-sided female contact configuration ensures reliable electrical connection across both edges of the circuit board.
• Cantilever spring contact design accommodates standard board tolerances while maintaining consistent mating force.
• Gold-plated terminals provide corrosion resistance and stable conductivity in demanding operational environments.

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device internal circuitry

Edgeboard Connectors Procurement Notes
