895-018-521-203

Edgeboard Connectors Overview

The EDAC Inc. 895-018-521-203 is a standard card edge connector receptacle featuring 18 positions with a 0.100-inch (2.54mm) pitch. Designed for vertical panel mount installation, it utilizes a solder pin termination type and gold-plated copper alloy contacts to ensure reliable signal transmission. The housing is constructed from black polyphenylene sulfide (PPS), providing robust insulation and thermal stability. This dual-edge female connector supports board thicknesses ranging from 0.054 to 0.070 inches, accommodating non-specified dual-edge cards within its operational temperature range of -40°C to +125°C.
