305-074-556-207

Edgeboard Connectors Overview

The EDAC Inc. model 305-074-556-207 is a standard card edge connector designed for vertical panel mounting applications. It features 74 positions with a 3.96 mm (0.156 inch) pitch across two rows. The connector utilizes gold-plated copper alloy contacts and solder lug termination. It accommodates board thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms. The unit operates within a temperature range of -40°C to +105°C and carries an RoHS3 compliant status.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct termination style and flange characteristics. Confirm that the required card thickness falls within the specified 1.37 mm to 1.78 mm range before integration. Check current availability status through authorized distributors as supply levels may vary. Ensure compliance with project-specific environmental regulations regarding RoHS3 standards.

Edgeboard Connectors Selection Notes

Select this component when a high-density 74-position interface is required for dual-edge card insertion. The 3.96 mm pitch allows for substantial trace spacing on printed circuit boards. Consider the vertical orientation and panel mounting requirements for enclosure design. Verify that the operating temperature range meets the environmental conditions of the intended application site.

Edgeboard Connectors Part Context
