346-027-558-658

Edgeboard Connectors Overview

The EDAC Inc. 346-027-558-658 is a standard card edge connector from the 346 series, designed for reliable signal transmission in electronic assemblies. It features 27 positions with a pitch of 3.175 mm (0.125 inches) and supports a board thickness of 1.57 mm. The connector utilizes gold-plated contacts on a copper alloy base to ensure low contact resistance and durability. It employs a PC pin termination type for secure mounting. The housing is constructed from thermoplastic polyester, providing mechanical stability and environmental resistance.
