305-054-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-558 is a dual-row card edge connector designed for panel mount applications. It features 54 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes gold-plated contacts on a copper alloy base, housed in a green thermoplastic insulator body. It supports a continuous current rating of 5A and withstands 1800VACrms dielectric voltage. The unit operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact installation requirements
• Provides reliable electrical connection through gold-plated half-beadle contacts

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct flange and termination specifications. Confirm that the required polarizing key type matches the application design. Check for updated compliance documentation such as REACH status prior to final procurement approval.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch spacing is required for 1.57mm thick PCBs. Ensure the mechanical layout accommodates the panel mount style and verify that the 5A current rating meets the system's power distribution needs without exceeding thermal limits.

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 tailored for vertical panel mounting. It is engineered for durability in demanding electronic environments while maintaining precise dimensional tolerances for consistent mating performance.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing pin counts or flange configurations. Verify compatibility with existing polarizing key mechanisms before substituting with similar industrial-grade connectors.
