305-034-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-034-520-558 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual-row configuration with 34 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is specified at 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). This component utilizes gold-plated copper alloy contacts to ensure conductivity and corrosion resistance. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, providing structural integrity and electrical insulation.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 34-position count and 3.96mm pitch before ordering. Confirm that the panel mounting style aligns with the mechanical enclosure design. Ensure the operating environment temperature does not exceed the rated limits of plus or minus 40 degrees Celsius to 105 degrees Celsius. Check for RoHS compliance requirements if applicable to the final assembly regulations. Validate that the PCB thickness is compatible with the connector's acceptance specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96mm spacing is required for .062 inch thick boards. Consider the 5A current rating and thermal stability for demanding applications. Compare against other 305 series variants if different position counts are needed. Evaluate the vertical panel mount constraint against available space in the chassis. Ensure the gold plating meets the environmental durability requirements for the intended use case.
