305-074-555-568

Edgeboard Connectors Overview

The EDAC Inc. model 305-074-555-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 74 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-beam contact type to ensure reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, providing insulation resistance of 5 GOhms. Designed for panel mounting in a vertical orientation, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm.
