305-064-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-064-556-268 is a standard card edge connector from the 305 series, designed for dual-edge board connections. It features a 64-position configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts gold-plated for conductivity, it utilizes a thermoplastic insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile thermoplastic insulator body accommodates standard PCB thicknesses
• Panel mount vertical installation style for structural stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure the target application supports the required 3.96 mm pitch and 1.57 mm board thickness constraints. Confirm compliance with relevant environmental standards such as RoHS requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for 64 signals on a standard thickness board. The 3.96 mm pitch offers robust spacing for high-current applications rated at 5 A. Consider the panel mount orientation and vertical angle for integration into chassis designs requiring fixed, non-flexible connections.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series provides various position counts and mounting options while maintaining consistent 3.96 mm pitch dimensions. These connectors are engineered for durability in demanding electronic environments requiring stable mechanical and electrical interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-064-556-502 or 305-064-520-268, provided they match the 64-position count and dual-edge specification. Verify that alternative suffixes maintain identical row spacing and PCB thickness acceptance criteria.
