305-074-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-568 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 74 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. It accommodates PCB 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

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features half-beadle contact type for robust mating engagement
• Utilizes thermoplastic insulator housing for structural stability

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control board connections
• Telecommunications hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical dimensions and material specifications. Ensure compatibility with target PCB thickness ranges and verify that the required polarizing key configurations are included in the final assembly order. Cross-reference datasheet revisions for any updates to operating temperatures or electrical ratings.

Edgeboard Connectors Selection Notes

Select this model when a high-density dual-row connection is required for panel mounting. The 3.96 mm pitch allows for substantial trace spacing, suitable for higher voltage isolation requirements. Confirm that the vertical installation style aligns with the chassis design and that the 5 A current capacity meets the circuit load demands without excessive heating.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and row configurations to support diverse interface needs. The 305-074 variant specifically provides a mid-range contact count optimized for balanced density and mechanical strength in industrial enclosures.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers with identical pitch and row configurations but different position counts, such as 305-070-556-568 or 305-080-555-568. Verify that alternative parts match the required panel mount style and vertical orientation before integration.
