305-054-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-278 is a dual-row standard card edge connector designed for panel mount applications. It features 54 positions with a 3.96 mm (0.156 inch) pitch, accommodating PCBs up to 1.57 mm thick. The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. Operating within a temperature range of -40°C to +105°C, it utilizes a thermoplastic polyester housing and solder pin termination.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure board-to-board or backplane connections
• Integrated card guide system for precise alignment during insertion
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Straddle mount design provides stable mechanical support on the panel

Edgeboard Connectors Applications

• Industrial control systems requiring robust I/O connectivity
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing color, and polarizing key options. Ensure that the selected variant matches the required PCB thickness tolerance and mounting style specifications for your assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance with current RoHS directives before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for panels supporting 1.57 mm thick circuit boards. The 3.96 mm pitch allows for substantial trace spacing, reducing crosstalk risks in high-noise environments. Consider the straddle mount feature if vibration resistance and mechanical stability are critical for the application's operational lifecycle.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, a family of standard card edge connectors known for durability and versatility. The series offers various position counts and mounting styles, catering to diverse industrial and commercial electronics needs. The 305-054-555-278 specifically addresses applications needing 54 channels with dual-row accessibility.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series sharing identical 54-position, dual-row, and 3.96 mm pitch specifications. Verify compatibility by comparing housing material, contact plating, and mounting orientation. Alternative manufacturers may offer similar form factors, but mechanical fit and electrical ratings must be validated against original design requirements.
