305-054-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-578 is a standard card edge connector header featuring 54 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for panel mounting via solder pin termination, it accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides a continuous current rating of 5 A with high dielectric strength

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the gold-plated copper alloy contacts meet the required environmental and electrical standards for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 54 positions is required. The 3.96 mm pitch suits applications needing robust mechanical stability. Verify that the panel mount installation style aligns with the enclosure design. Ensure the operating temperature range of -40°C to +105°C meets the system's thermal requirements.

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 accommodating specific PCB thicknesses. The 305 series provides a reliable connection solution for double-sided edge cards in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 54-position count and 3.96 mm pitch. Verify identical row spacing and PCB thickness acceptance before substitution. Consult the official EDAC ordering guide for compatible alternative part numbers within the same product family.
