305-058-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 58 positions and a pitch of 3.96 mm (0.156 inches). The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector supports PCB thicknesses of 1.57 mm. It utilizes solder pin termination and is housed in green thermoplastic material, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual edge female contact configuration for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic housing providing structural stability
• Vertical panel mount design for fixed installation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact housing color and termination style variations. Ensure compatibility with target PCB thickness of 1.57 mm before integration. Cross-reference insulation resistance specifications of 5 GOhms for high-voltage isolation requirements. Confirm lead-free compliance status through current datasheets.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 58 positions is required for panel-mounted systems. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Gold plating is essential for environments requiring long-term oxidation resistance. Verify that the vertical mounting style aligns with chassis layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent electrical ratings. The 305-058-521-258 specifically addresses needs for moderate-density connections in industrial settings where robust mechanical retention is prioritized over miniaturization.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 58-position counts and 3.96 mm pitch. Verify identical housing materials and contact plating specifications before substitution. Non-OEM alternatives must match the 1.57 mm PCB thickness tolerance and vertical mounting geometry.
