305-040-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-040-520-258 is a standard card edge connector from the 305 series, designed for panel-mounted applications. It features a dual-row configuration with 40 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm, accommodating printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts plated in gold, this header supports a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is made of green thermoplastic, providing reliable insulation.

Edgeboard Connectors Feature Summary

• Dual-row female connector design accepting between-contact and in-contact polarizing keys
• Low profile insulator body constructed from green thermoplastic material
• Gold-plated copper alloy contacts ensure durable electrical performance
• Panel mount vertical installation style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel connections
• Embedded hardware interfaces needing polarized keying options
• General-purpose electronic assemblies utilizing standard card edge modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the panel mounting requirements align with the vertical orientation of this connector type. Cross-reference the 40-position count with system design constraints to avoid mismatched interface configurations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge solution with polarizing capabilities is required. The 3.96 mm pitch suits applications needing wider spacing compared to standard 2.54 mm connectors. Consider the 5 A current rating for power distribution needs within the interface. The panel mount style dictates integration into chassis or enclosure structures rather than board-to-board stacking.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting options and row spacings. The series is characterized by its ability to accept polarizing keys for secure alignment. Similar models in the lineup vary primarily by position count and specific mounting configurations while maintaining consistent contact spacing and material standards.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 40-position count, 3.96 mm pitch, and dual-row layout. Verify that alternative components support the same 1.57 mm PCB thickness and panel mount orientation. Ensure equivalent current ratings and voltage withstand capabilities are maintained for safe operation.
