355-070-556-504

Edgeboard Connectors Overview

The EDAC Inc. 355-070-556-504 is a dual-edge female card edge connector from the 355 series, featuring 70 positions arranged in two rows of 35 contacts each. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The connector employs half-beam contact types with gold plating for reliable signal transmission. Designed for through-hole solder termination, it operates within a temperature range of -40°C to +105°C and features a black thermoplastic polyester insulator body.
