305-040-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-501 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. It supports solder pin termination and accommodates board thicknesses between 1.37 mm and 1.78 mm. The component operates within a temperature range of -40°C to +105°C and carries a 5 A current rating.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm plating thickness, housing color, and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate mechanical dimensions against enclosure requirements.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 40-position interface with a 3.96 mm pitch is required. Consider the 5 A current rating and operating temperature range for environmental suitability. Verify that the target application utilizes non-specified dual-edge cards compatible with the connector's contact design. Evaluate panel mounting constraints to ensure proper fitment.
