305-074-556-212

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-212 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 74-position configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. Rated for 5 A current, it supports panel mount installation at a vertical angle. The unit accommodates a board thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure dual-edge card engagement
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and insulation
• Vertical panel mount design facilitates fixed installation in enclosures

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing dual-edge module interfaces
• Automotive electronics assemblies needing high-reliability connectors
• Test and measurement instrumentation with modular card architectures

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm plating thickness, housing color, and termination style. Ensure the target PCB thickness matches the 1.57 mm specification. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure design requirements before finalizing the order.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface is required with a 3.96 mm pitch. The 74-position count suits applications needing extensive signal or power routing. Verify that the 5 A current rating meets the circuit load requirements. Consider the vertical mounting style if space constraints dictate a perpendicular connection relative to the chassis.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-074-556-212 specifically denotes the 74-position variant with dual-edge compatibility. It is engineered for high-reliability environments common in industrial and commercial electronics sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series for alternative position counts. Verify that any substitute maintains the 3.96 mm pitch and dual-row female configuration. Ensure mechanical dimensions and mounting styles are identical to prevent PCB layout modifications.
