305-070-500-202

Edgeboard Connectors Overview

The EDAC 305-070-500-202 is a standard card edge connector from the 305 series, designed for dual-side contact applications. It features 70 positions with a 1.57 mm (0.156 inch) pitch and accommodates a board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and supports a continuous current rating of 5 A. It employs a solder lug termination style and is configured for panel mount installation at a straight angle. The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-side contact configuration for reliable signal transmission
• Gold-plated copper alloy contacts ensure corrosion resistance
• Thermoplastic polyester housing provides structural stability
• Solder lug termination facilitates secure panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation panels
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with your design requirements. Ensure that the panel mount orientation and solder lug termination style align with your assembly process. Cross-reference the 70-position count and 1.57 mm pitch with your PCB layout specifications to prevent mechanical interference. Confirm that the thermal and electrical ratings meet your system's operational standards before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-density, dual-sided connection is required for panel-mounted applications. The 5 A current rating and gold plating make it suitable for environments demanding durability and low contact resistance. Consider the straight panel mount style if space constraints allow for perpendicular insertion. Evaluate the 1.57 mm board thickness compatibility to ensure proper fit within your enclosure design without requiring additional adapters or spacers.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate different board densities. The 305-070-500-202 specifically addresses needs for 70-contact interfaces with panel-mount flexibility, distinguishing it from PCB-mount variants within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 70 positions and panel mount configurations, such as 305-070-556-568, provided the termination style and pitch remain compatible. Verify that any alternative maintains the same 1.57 mm pitch and dual-side contact capability to ensure functional equivalence in existing designs.
