305-028-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-578 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 28 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Rated for 5 A continuous current and 1800 VACrms insulation voltage, it supports solder pin termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body constructed from thermoplastic material
• Dual row female contact design with gold plating for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
