305-076-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-207 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 76 positions with a 0.156-inch (3.96mm) pitch and supports two rows of contacts. The connector utilizes female half-beadle terminals with gold plating over copper alloy substrates. It accommodates PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C, and complies with RoHS3 standards.
