305-012-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 12 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and solder lug termination for secure electrical connections. It is rated for 5 A continuous current and supports printed circuit boards with a nominal thickness of 1.57 mm. The insulator body is constructed from thermoplastic material, providing reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced board alignment and security
• Features a low-profile insulator body suitable for space-constrained panel installations
• Supports dual-edge card types with robust gold-plated contact surfaces for signal integrity

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical card edge interfacing
• Industrial control systems utilizing polarized PCB modules
• Communication equipment housing dual-row connector interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style and insulation color. Confirm compatibility with the target PCB thickness of 1.57 mm before integration. Ensure that the polarizing key requirements align with the design specifications, as this connector accepts both between-contact and in-contact keys. Cross-reference the RoHS status and environmental classifications against project compliance standards prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-row card edge applications. The 3.96 mm pitch and 1.57 mm board thickness compatibility are critical constraints for selection. Consider the 5 A current rating and high-temperature tolerance when evaluating thermal management needs. Verify that the gold plating and copper alloy construction meet the conductivity and corrosion resistance requirements of the intended environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their versatility in mounting styles and contact configurations. The series offers various position counts and termination options to accommodate diverse electronic packaging needs. Components in this family typically feature thermoplastic insulators and gold-plated contacts to ensure reliable performance in demanding industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating variations in termination or insulation. Verify that any replacement maintains the 1.57 mm board thickness compatibility and vertical panel mount orientation. Ensure that the alternative part supports the same polarizing key acceptance capabilities.
