305-048-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-048-555-508 is a standard card edge connector header featuring 48 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with gold plating, providing a continuous current rating of 5 A. Designed for panel mounting at a vertical angle, the unit includes flange features such as top opening and threaded inserts.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high insulation resistance rated at 5 GOhms

Edgeboard Connectors Applications

• Panel-mounted electronic interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange configuration, as variations exist within the series. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment remains within the specified operating temperature limits of -40°C to +105°C. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel installation. The 48-position count suits applications needing moderate density connections. Verify that the gold-plated copper alloy contacts meet the corrosion resistance requirements. Ensure the mechanical design accommodates the vertical mounting style and available flange attachment points.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and termination styles. The 305-048-555-508 specifically denotes the 48-position variant with gold contacts and panel mount capabilities. Similar parts in the series include the 305-018-555-508 and 305-054-555-508, differing primarily in position count while maintaining consistent electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-048-556-508 and 305-048-500-201. Verify that alternative part numbers match the required 48-position count and 3.96 mm spacing. Check if the replacement variant supports the necessary panel mounting style and flange features.
