305-020-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-020-500-278 is a standard card edge connector from the 305 Series, designed for dual-row applications with a 3.96 mm (0.156 inch) pitch. It features 20 positions and supports a board thickness of 1.57 mm. The component utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. Rated for 5 A current at voltages up to 500 V, it offers an insulation resistance of 5 GOhms. The unit employs a panel mount style with solder eyelet termination for secure PCB attachment. Operating within a temperature range of -40°C to +105°C, the housing is constructed from thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 20 contact positions for high-density interconnects
• Gold-plated copper alloy contacts ensuring durability and low contact resistance
• Panel mount design with solder eyelet termination for robust mechanical stability

Edgeboard Connectors Applications

• Industrial control systems requiring reliable card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact termination style and mounting configuration. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the dual-row layout aligns with the system's pinout requirements. Cross-reference the electrical ratings with the application's voltage and current demands to prevent operational failure.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 20-position count suits moderate density needs. Verify that the operating environment falls within the specified temperature range. Consider the solder eyelet termination method if through-hole mounting is preferred over surface mount alternatives. Ensure the thermoplastic housing meets the mechanical constraints of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series provides various mounting options and row configurations to accommodate different electronic design requirements. Components in this line are characterized by their consistent 3.96 mm pitch and robust construction suitable for demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the same 3.96 mm pitch, 20-position count, and dual-row configuration. Verify that alternative components support the same panel mount style and solder eyelet termination to preserve mechanical fit.
