305-074-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-268 is a standard card edge connector from the 305 Series, designed for dual-row applications with 74 positions. It features a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. It is rated for 5 A current and offers an insulation resistance of 5 GOhms. The unit operates within a temperature range of -40°C to +105°C and employs a thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration providing two rows of contact points for high-density interconnects.
• Gold-plated copper alloy contacts ensure durability and low contact resistance.
• Low-profile insulator body design accommodates space-constrained panel installations.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
