305-084-520-578

Edgeboard Connectors Overview

The EDAC Inc. part number 305-084-520-578 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 84 positions with a 0.156-inch (3.96 mm) contact pitch and accepts PCB thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts rated for 5 A continuous current and 1800 VACrms insulation voltage. It employs a panel mount installation style with a threaded flange feature using 4-40 inserts 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
• Provides high dielectric strength with 1800 VACrms insulation rating
• Features a threaded flange design for robust panel mounting stability

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• High-voltage signal transmission modules
• Panel-mounted electronic assemblies needing secure mechanical retention

Edgeboard Connectors Procurement Notes

Verify that the specific application requires the 305 series dual-edge configuration with 84 positions. Confirm compatibility with the specified 0.156-inch pitch and 4-40 threaded flange requirements. Ensure the operating environment remains within the -40°C to 105°C temperature range. Check for necessary polarizing key accessories if between-contact or in-contact polarization is required for the assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a high pin count is necessary. The 305 series is suitable for applications demanding a 5 A current rating and 1800 VACrms isolation. Consider the panel mount style and threaded flange feature for installations requiring rigid mechanical fixation. Verify that the target PCB thickness falls within the 0.054 to 0.070 inch specification.
