857-074-420-212

Edgeboard Connectors Overview

The EDAC Inc. 857-074-420-212 is a card edge connector designed for dual-edge board applications. It features 74 positions with a 0.156-inch (3.96mm) contact spacing and 0.200-inch (5.08mm) row spacing. The housing is constructed from black polyphenylene sulfide (PPS), providing thermal stability up to +125°C. Contacts are tin-plated copper alloy, ensuring reliable conductivity. This through-hole mount connector supports PCB thicknesses between 0.054 and 0.070 inches.
