305-076-521-207

Edgeboard Connectors Overview

The EDAC Inc. model 305-076-521-207 is a standard card edge connector from the 305 series, designed for dual female edgeboard applications. It features 76 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a half-bermuda termination style and solder pin end-type. Constructed with thermoplastic polyester insulation, it operates within a temperature range of -40°C to +105°C and meets RoHS3 standards.
