305-036-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-036-500-278 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features 36 positions with a dual-edge female contact configuration and a 0.156-inch (3.96mm) pitch. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. This component supports printed circuit boards with a thickness of 1.57mm and provides a continuous current rating of 5A with an insulation resistance of 5 GOhms. 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 secure board alignment
• Vertical panel mount design facilitates structured chassis integration
• Gold-plated copper alloy contacts provide durable electrical connectivity

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Electronic instrumentation panels needing vertical mounting solutions
• Communication equipment chassis utilizing standardized card interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required polarizing key compatibility and termination style. Confirm the voltage rating requirements align with the 1800VACrms specification provided for this series. Ensure the PCB thickness tolerance corresponds to the 1.57mm design parameter before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when vertical orientation and polarizing key support are necessary for mechanical stability. The 36-position count suits moderate-density interconnect needs. Verify that the 5A current rating meets the application's power distribution requirements and that the operating temperature range covers the environmental conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by robust construction suitable for demanding environments. The 305-036-500-278 variant specifically addresses applications requiring vertical mounting and polarizing key acceptance, distinguishing it from non-polarized or horizontal variants within the broader product family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 36-position counts and vertical mounting styles. Verify that alternative part numbers support the same polarizing key configurations and maintain identical pitch and current ratings.
