305-024-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-024-555-278 is a standard card edge connector from the 305 Series, featuring a dual-row configuration with 24 positions and a 3.96 mm (0.156 inch) contact spacing. It utilizes gold-plated copper alloy contacts with a half-beam spring termination type for reliable signal transmission. The insulator body is constructed from green thermoplastic polyester, designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). This component supports panel mount installation via threaded flange inserts and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge card interface with half-beam spring contacts for secure board retention
• Gold-plated copper alloy terminals ensure corrosion resistance and stable conductivity
• Thermoplastic polyester insulator provides thermal stability and mechanical durability
• Panel mount design with threaded flange inserts for robust structural integration

Edgeboard Connectors Applications

• Industrial control system backplanes requiring high-reliability interconnects
• Telecommunications equipment housing modular circuit cards
• Test and measurement instrumentation with frequent board insertion cycles
• Automotive electronic modules operating in varied thermal environments

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and termination specifications, as variations exist within the 305 series. Confirm compliance with RoHS3 directives if environmental regulations apply to your assembly. Ensure the PCB thickness falls within the specified 1.37mm to 1.78mm range to guarantee proper contact engagement. Cross-reference the manufacturer's latest datasheet for any updates on material composition or mounting hardware requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a dual-row connection with 3.96mm pitch is necessary for high-density applications. The threaded flange option offers superior vibration resistance compared to snap-in variants. Consider the 1.57mm board thickness compatibility during mechanical design. Evaluate the operating temperature range against your environment to ensure the thermoplastic insulator remains effective. Compare row spacing and contact count against alternative series if space constraints differ.

Edgeboard Connectors Part Context

This component belongs to EDAC's 305 Series, which encompasses various card edge connectors with standardized 3.96mm spacing. The series differentiates models through position counts, termination types, and mounting styles. The 305-024-555-278 specifically denotes a 24-position dual-row unit with threaded panel mount features. It shares common electrical characteristics with other 305 series parts but varies mechanically based on the suffix codes defining flange and tail configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-024-555-202 and 305-024-555-578, though these may feature different flange types such as snap-in or unthreaded options. Verify that the replacement maintains the 3.96mm pitch and 24-position count. Ensure the new variant supports the same 1.57mm board thickness and current rating. Check if the termination style matches your PCB layout requirements.
