387-022-559-268

Edgeboard Connectors Overview

The EDAC Inc. 387-022-559-268 is a dual-row female card edge connector from the 387 Series, designed for straddle mount installation via solder pin termination. It features 22 positions with a 0.156-inch (3.96mm) contact spacing and 0.200-inch (5.08mm) row spacing. The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with thermoplastic polyester insulation and copper alloy contacts, it offers gold plating on mating areas and tin plating on tails. Rated for 3 amps at 1800 V AC rms, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with high-profile insulator body providing 0.600-inch card slot depth
• Accepts standard 0.062-inch nominal thickness PCBs with single or dual row configurations
• Gold-plated mating area ensures reliable signal transmission while tin-plated tails facilitate soldering

Edgeboard Connectors Applications

• High-density electronic assemblies requiring robust board-to-board connections
