305-052-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-052-556-204 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features 52 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, and the housing utilizes thermoplastic polyester material.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for secure board retention
• Dual row contact arrangement for high-density connections
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester insulator body for durability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB form factors
• Test and measurement devices needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times. Confirm RoHS compliance requirements match project specifications.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for 52-position card edge applications. The 3.96 mm pitch accommodates standard double-sided PCBs. Consider the 5 A current rating and 105 C maximum operating temperature for thermal management planning. Verify that the dual-row configuration fits within the available chassis space constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 305-052 variant specifically addresses applications requiring moderate pin counts with vertical orientation. It serves as a critical interconnect element between backplanes and daughter cards in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Check for direct substitutes within the EDAC 305 family that share identical pin counts and mounting styles. Verify cross-compatibility with other manufacturers' 305-series equivalents by comparing dimensional drawings and electrical ratings.
