305-050-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-507 is a standard card edge connector featuring 50 positions arranged in a dual-row configuration with a 3.96 mm pitch. Designed for panel mount and through-hole termination, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The unit supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. It accommodates printed circuit boards with a thickness between 1.37 mm and 1.78 mm, housed in a green thermoplastic polyester insulator.

Edgeboard Connectors Feature Summary

• Accepts both between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Equipped with half-beam contact type for robust mechanical retention

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Automotive electronics modules demanding durable panel-mounted connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm that the required polarizing key style matches the connector's acceptance capabilities. Cross-reference the RoHS status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm spacing is required for vertical panel mounting. The 50-position count suits applications needing moderate I/O density without excessive footprint. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry. Consider the operating temperature range if the environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and termination styles to accommodate diverse design constraints. Components in this family typically feature gold-plated contacts and thermoplastic housings for durability and conductivity.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for verified substitute part numbers with equivalent pin counts and pitch dimensions. Direct replacements must maintain the dual-row configuration and compatible PCB thickness specifications.
