305-038-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-038-555-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 38 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact installation requirements
• Provides high dielectric strength with a 1800VACrms rating

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge connections
• Industrial control systems utilizing polarized PCB integration
• High-voltage interface modules within enclosed equipment racks

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure compatibility with required polarizing key configurations and mounting hardware. Confirm that the target printed circuit board thickness aligns with the specified 0.062-inch nominal requirement for proper mechanical retention and electrical contact reliability during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with polarizing key acceptance is required for panel mounting. Ensure the application environment remains within the operational temperature range and that the PCB design accommodates the 3.96 mm pitch. Verify that the 5 A current rating meets the system's electrical load demands without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their versatility in accepting various polarizing keys and supporting nominal 1.57 mm board thicknesses. The series offers multiple position counts and mounting styles, providing a standardized solution for reliable interconnects in industrial and commercial electronics applications.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series base code but differing only in position count or mounting style suffixes. Ensure any substitute maintains the 3.96 mm pitch and 38-position configuration while verifying identical polarizing key compatibility and voltage ratings.
