845-112-540-504

Edgeboard Connectors Overview

The EDAC Inc. 845-112-540-504 is a high-temperature card edge connector from the 845 series, designed for dual-edge board insertion. It features 112 contacts arranged in two rows with a 0.100-inch (2.54mm) pitch. The connector utilizes female wire wrap terminals and a green insulator made of diallyl phthalate (DAP). Contact plating is specified as gold to ensure reliable signal transmission in demanding environments.
