305-070-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-202 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 70 positions with a 0.156-inch (3.96 mm) pitch and supports double-row female contacts. The connector utilizes gold-plated copper alloy terminals with a 10.0 µin thickness and half-wave spring contact type. It accommodates PCB thicknesses between 0.054 and 0.070 inches (1.37–1.78 mm). The unit employs a panel mount vertical installation style with solder pin termination. Insulation is provided by green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector configuration supporting non-specified dual edge boards
• Gold-plated copper alloy half-wave spring contacts for secure signal transmission
• Thermoplastic polyester insulation housing with flange features for panel mounting
• Vertical panel mount design with solder pin termination for stable integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instrumentation with high-density connection needs
• Automotive electronics modules demanding reliable vertical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact physical dimensions and plating specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate that the 70-position dual-row layout matches the circuit board footprint design.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface is required for vertical panel mounting. The 0.156-inch pitch suits applications needing moderate density without excessive miniaturization. The gold plating offers corrosion resistance suitable for harsh environments. Consider the half-wave contact type for reliable mating cycles. Ensure the thermoplastic polyester insulator meets thermal stability requirements for the intended operating temperature range up to 105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles. The 305 series typically features flanged housings for secure panel attachment. It is widely used in industrial and commercial electronics where reliable board-to-board or board-to-panel connections are essential. The model number structure indicates specific attributes regarding position count, row configuration, and housing style.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 series ordering guide for direct substitutes with different position counts or flange variations. Verify that any alternative maintains the 0.156-inch pitch and dual-edge female configuration. Ensure mechanical compatibility with existing panel cutouts and PCB thickness constraints before substitution.
