305-054-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-258 is a standard card edge connector header featuring 54 positions 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 printed circuit boards with a nominal thickness of 1.57 mm. The component employs gold-plated copper alloy contacts and solder pin termination for secure panel mounting at a vertical angle. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Features a low-profile thermoplastic insulator body for compact integration
• Provides high dielectric strength with 1800 VACrms insulation resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing thick PCB architectures
• Test and measurement instrumentation demanding high-current signal paths

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with wide 3.96 mm pitch is required for high-density applications. The 54-position count suits moderate-to-high I/O density needs. Verify that the 5 A current rating meets the thermal management capabilities of the system environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series is characterized by its ability to accommodate various PCB thicknesses and support polarizing keys. The 305-054-520-258 variant specifically addresses applications needing a 54-pin dual-row interface with robust electrical ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 54-position counts and 3.96 mm pitch, such as the 305-054-520-208 or 305-054-556-278, provided the housing color and specific termination details match the assembly requirements.
