305-054-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-268 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual-row configuration with 54 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The insulator body is green thermoplastic polyester. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accepting non-specified PCBs
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator body with low profile construction
• Panel mount vertical installation style

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain material integrity. Check for specific ordering suffixes that may alter physical dimensions or plating specifications. Validate supply chain sources against manufacturer lists to avoid counterfeit parts.

Edgeboard Connectors Selection Notes

Select this model when a 54-position dual-row interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing than standard connectors. Verify PCB thickness compatibility within the 1.37 mm to 1.78 mm range. Consider the 5 A current rating for power distribution needs. Evaluate thermal requirements against the -40°C to +105°C operating window.

Edgeboard Connectors Part Context

Part of the EDAC 305 series, which offers various mounting options and position counts. The series supports between-contact and in-contact polarizing keys for secure mating. Similar models include 305-040-520-268 and 305-054-556-278, differing in position count or specific feature sets while maintaining the same pitch and form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include 305-054-520-568 and 305-054-556-278. Verify pin count, pitch, and mounting style match before substitution. Cross-reference datasheets for any changes in insulation resistance or voltage ratings.
