305-070-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-070-555-258 is a standard card edge connector featuring 70 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for panel mounting at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and finished with gold plating to ensure reliable conductivity. Rated for 5 A current, the connector employs a solder lug termination method.

Edgeboard Connectors Feature Summary

• Dual-row architecture providing 70 contact positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensuring durable electrical performance
• Vertical panel mount design compatible with standard 1.57 mm thick PCBs

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 70-position dual-row specification. Confirm that the 3.96 mm pitch aligns with the target PCB layout. Ensure the panel mounting style suits the enclosure design. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge interface is required. The 5 A rating supports substantial power delivery alongside signal transmission. The vertical orientation simplifies board stacking or rear-panel integration. Verify that the thermoplastic insulator body meets the thermal requirements of the operating environment.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-070 variant specifically addresses applications needing extensive I/O connections within a compact footprint. The design prioritizes mechanical stability and consistent contact resistance.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 70-position dual-row layouts. Ensure replacement parts maintain the 3.96 mm pitch and 1.57 mm board thickness compatibility. Verify identical mounting styles and termination types to preserve mechanical fit.
