305-076-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-076-520-507 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features 76 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy and gold-plated, supporting a continuous current rating of 5 A. The housing is constructed from green thermoplastic material. It accommodates 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

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides high dielectric strength with an 1800VACrms insulation rating
• Features semi-waffle spring contact design for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel connections
• Telecommunications equipment interface modules
• Automotive electronics assemblies
• Medical device internal circuitry

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct contact plating thickness and housing color specifications. Confirm that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Check RoHS compliance status via the manufacturer's latest documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for panel-mount applications. Ensure the mating card edge thickness aligns with the specified mechanical limits. Consider the 5 A current rating and 1800VACrms insulation requirements for electrical safety margins in the system design.

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 styles. The 305-076 variant specifically provides 76 positions, distinguishing it from lower-count models like the 305-050 or higher-count alternatives within the same product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 76-position count, 3.96 mm pitch, and dual-row configuration. Verify compatibility with existing polarizing key requirements and panel mount dimensions.
