305-048-500-504

Edgeboard Connectors Overview

The EDAC Inc. 305-048-500-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 48 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) pitch. The connector accepts dual-edge cards with a thickness range of 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating and terminate via solder pins. The housing is constructed from green thermoplastic polyester, supporting a current rating of 5 A and operating temperatures between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, material specifications, and packaging details. Ensure compatibility with the target card edge thickness and panel cutout dimensions before procurement. Cross-reference the full part number with authorized distributors to confirm availability and lead times, as supply chain status may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted installations. The 48-position count suits applications needing moderate I/O density. Verify that the operating environment stays within the specified temperature range and that the mating card thickness falls within the 1.37–1.78 mm tolerance. Consider the vertical mounting style for space-constrained chassis designs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations for card edge applications. The series is characterized by its use of thermoplastic housings and gold-plated contacts, providing durability in demanding environments. The 305-048 variant specifically addresses needs for 48-position dual-edge connections with panel-mount capabilities.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative part numbers with different position counts or housing colors. Direct substitutes must maintain the 3.96 mm pitch and dual-edge female configuration to ensure mechanical and electrical compatibility with existing designs.
