305-012-520-504

Edgeboard Connectors Overview

The EDAC 305-012-520-504 is a standard card edge connector from the 305 series, designed for dual female board-to-board or backplane applications. It features 12 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts gold-plated for reliability, it supports a continuous current rating of 5 A and withstands 1800 VACrms. The low-profile thermoplastic insulator body ensures compact integration.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Low profile insulator body design for space-constrained installations
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board connections
• Test and measurement instruments needing high-reliability connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm pin count, plating, and mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the required polarizing key configuration matches the application needs, as the connector supports both between-contact and in-contact options. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 12-position interface is required with a 3.96 mm pitch. It is suitable for applications demanding a 5 A current rating and high dielectric strength. Consider the vertical panel mount style if used in chassis-based systems. Verify that the mating card edge thickness aligns with the specified 1.57 mm nominal dimension to ensure proper mechanical engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations for standard card edge applications. The series is characterized by its durable thermoplastic construction and gold-plated contacts. Similar models in the series vary primarily in the number of positions and specific mounting hardware, sharing common electrical ratings and dimensional standards.

Edgeboard Connectors Replacement Considerations

Direct replacements within the EDAC 305 series include models with identical 12-position layouts and 3.96 mm spacing. Verify that any substitute maintains the same 1.57 mm PCB thickness tolerance and 5 A current rating. Ensure the replacement part supports the necessary polarizing key requirements for the specific assembly.
