305-028-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-504 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features a dual-edge female configuration with 28 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It supports a nominal printed circuit board thickness of 1.57 mm and offers a continuous current rating of 5 A. The insulator body is constructed from thermoplastic material, providing a low-profile design suitable for dense electronic assemblies.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the selected variant meets the required environmental standards, such as RoHS compliance, for your specific application region. Cross-reference the part number with the latest datasheet to avoid discrepancies in contact count or row spacing.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch accommodates standard board layouts while maintaining a compact profile. Consider the 5 A current rating for power distribution needs. Verify that the housing material and temperature range (-40°C to +105°C) align with the operational environment. Ensure the solder pin termination method matches the assembly process capabilities.
