305-076-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-076-520-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 76-position configuration with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The unit utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A continuous current, it supports PCB thicknesses of 1.57 mm nominal. The connector employs through-hole solder pin termination and offers straight mounting orientation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body design
• Provides high dielectric strength with 1800VACrms rating

Edgeboard Connectors Applications

• Dual-side card edge interconnections
• Industrial control systems requiring polarized keying
