387-050-556-202

Edgeboard Connectors Overview

The EDAC Inc. 387-050-556-202 is a dual-edge card edge connector featuring 50 positions with a 0.156-inch (3.96 mm) pitch. Designed for through-hole mounting, it utilizes female contacts made of copper alloy with a gold plating thickness of 10.0 µin (0.25 µm). The housing is constructed from black thermoplastic polyester, supporting PCB thicknesses between 0.054 and 0.070 inches. It operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration provides two rows of contacts for high-density signal routing.
• Gold-plated cantilever spring contacts ensure reliable electrical connection and corrosion resistance.
• Thermoplastic polyester insulation offers stable mechanical performance across wide temperature ranges.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
