305-048-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-278 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 48 positions with a 3.96 mm (0.156 inch) contact spacing and dual rows. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A current at an insulation resistance of 5 GOhms. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 48 positions for high-density signal routing
• Vertical panel mount design with solder pin termination for secure PCB attachment
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic insulator body supports operation across extended industrial temperature ranges

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation interfaces
• Automotive electronics assemblies needing durable vertical connectors

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status and specific gold plating thickness requirements against project specifications. Ensure storage conditions maintain integrity of the thermoplastic housing and contact surfaces prior to assembly.

Edgeboard Connectors Selection Notes

Select this model when a 48-position dual-row connector is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing than standard .100 inch headers. Verify that the target PCB thickness aligns with the 1.57 mm nominal specification for proper mechanical retention and electrical contact.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and panel mount characteristics. It serves as a reliable interface solution for modular electronic designs requiring durable, high-contact-count connections in constrained spaces.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series for alternative position counts. Verify mechanical dimensions and electrical ratings match before substituting. No direct public substitute part numbers are confirmed for identical specifications.
