305-050-520-508

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-508 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 50 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C. Contacts are made of copper alloy with gold plating, housed in a thermoplastic insulator.

Edgeboard Connectors Feature Summary

• Supports between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction
• Provides 1800VACrms dielectric voltage capability

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connection
• Industrial control systems utilizing standardized card edge interfaces
• Test and measurement equipment needing robust vertical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination style. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm RoHS compliance status through the latest product documentation before integration into regulated environments.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided card edge circuits. The 3.96 mm pitch accommodates standard board layouts while maintaining high current capacity. Verify that the application environment stays within the specified -40°C to +105°C operational limits and requires gold-plated contacts for corrosion resistance.

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, all sharing common electrical ratings and mechanical design principles. The 305 series is widely used in industrial and commercial electronics for reliable signal and power transmission via card edge interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-050-520-578 or 305-050-520-201 for alternative packaging or minor mechanical differences. Ensure any substitute maintains the same 3.96 mm pitch, 50-position count, and vertical panel mount configuration.
