305-052-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-202 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-row configuration providing 52 positions with a 3.96 mm pitch. The connector accepts PCBs with a thickness of 1.57 mm and utilizes solder pin termination. Electrical specifications include a 5 A current rating and 1800 VACrms dielectric strength. Contacts are gold-plated copper alloy, housed in thermoplastic insulation, supporting an operating temperature range of -40 C to +105 C.

Edgeboard Connectors Feature Summary

• Dual-side contact design accommodating between-contact and in-contact polarizing keys
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic housing provides structural integrity and electrical insulation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized modular connections
• Test and measurement instrumentation needing high-density I/O

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 thermal stability within specified limits. Cross-reference datasheet revisions to confirm parameter consistency. Validate mechanical dimensions against target PCB layout requirements prior to procurement.

Edgeboard Connectors Selection Notes

Select this model when a 52-position dual-row interface is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications needing moderate density without excessive miniaturization. Verify that the 5 A current rating meets system power distribution needs. Consider the vertical panel mount style for chassis integration. Assess environmental tolerance requirements against the -40 C to +105 C operational range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent mechanical and electrical standards. The 305-052-520-202 variant specifically addresses high-pin-count applications requiring dual-sided connectivity. It complements other 305 series parts by offering a specific 52-position configuration for specialized board designs.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the 305 series include 305-040-520-268 and 305-038-520-502, which share identical pitch and mounting characteristics but differ in position count. Verify that alternative part numbers match the required 52-position specification. Ensure replacement components maintain the same 1.57 mm board thickness compatibility and vertical orientation constraints.
