305-012-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-012-520-258 is a standard card edge connector featuring 12 positions in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The component employs solder pin termination for secure attachment. Constructed with copper alloy contacts finished in gold, it ensures reliable conductivity. Rated for 5 A continuous current and 1800 VACrms insulation, the connector operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Features a vertical panel mount style with a green thermoplastic polyester housing
• Provides robust electrical performance with specified current and voltage ratings

Edgeboard Connectors Applications

• Industrial control systems requiring secure board-to-board connections
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing reliable high-voltage isolation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating thickness and housing color specifications. Ensure compatibility with existing panel cutouts and PCB stack-up requirements before finalizing procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and compliance with relevant environmental directives such as RoHS.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting. The 12-position count suits applications needing moderate I/O density without excessive footprint. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the 5 A current rating and 1800 VACrms insulation strength for appropriate electrical safety margins in the design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, designed for general-purpose interconnect solutions. The series offers various position counts and termination styles to accommodate diverse board layouts. As a panel-mount header, it provides stable mechanical support for inserted circuit cards while maintaining consistent electrical contact integrity across the operating temperature spectrum.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 12-position dual female configuration, 3.96 mm pitch, and vertical panel mount style. Verify identical current ratings and insulation voltages to ensure system safety. Check for compatible polarizing key acceptance features if mechanical locking is critical to the assembly.
