305-072-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-508 is a standard card edge connector from the 305 series, designed for dual-edge female mating applications. It features 72 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable electrical performance. The unit utilizes a solder termination method and is housed in a green thermoplastic polyester insulator body.
