305-074-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-212 is a standard card edge connector designed for vertical panel mount applications. It features 74 positions arranged in a dual row configuration with a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing, rated for a current of 5 A. It supports board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design ensures reliable electrical connection for non-specified card types.
• Vertical panel mount style provides secure mechanical stability for straddle mounting configurations.
• Gold-plated copper alloy contacts offer corrosion resistance and stable signal transmission.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing high-reliability connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the vertical mounting orientation aligns with system mechanical constraints. Cross-reference part numbers to avoid confusion with similar series variants.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 74-position interface is required for vertical panel integration. Consider the 3.96 mm pitch requirement for trace routing density. Evaluate the 5 A current rating against system power distribution needs. Assess the operating temperature range against environmental conditions. Verify that the thermoplastic polyester housing meets flame retardancy standards for the application.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and pitch options to accommodate diverse electronic module designs. The 305 series is widely recognized for its durability and consistent performance in demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternatives. Ensure replacement parts maintain identical pitch, position count, and mounting style. Verify that substitute components meet the same electrical and thermal ratings. Check for any changes in housing material or contact finish that might affect compatibility.
