305-026-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-502 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 26 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing mechanical stability and electrical insulation.
