305-054-556-208

Edgeboard Connectors Overview

The EDAC 305-054-556-208 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 54 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) contact spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch).

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment.
• Features semi-bellows contact type for reliable mating engagement.
• Includes flush mount flange with top opening and threaded inserts.

Edgeboard Connectors Applications

• Vertical panel-mounted interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the required polarizing key accessories are sourced separately if needed for the assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 54-position connection is required in a vertical orientation. The 3.96 mm pitch accommodates standard board layouts while maintaining robust electrical performance. Consider the integrated flange design for applications requiring direct panel attachment without additional bracketry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its suitability for both single and double-sided edge cards. The 305 series provides a balance of mechanical stability and electrical reliability for industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants having identical pin counts and pitch. Verify that alternative parts support the same 1.57 mm board thickness and vertical mounting style to ensure mechanical fit.
