305-048-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-048-500-578 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 a dual row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector utilizes gold-plated copper alloy contacts with a half-bellows type for reliable engagement. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches), ranging from 1.37 mm to 1.78 mm. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates non-specified card types with half-bellows contact geometry for secure mating.
• Gold-plated copper alloy contacts ensure high conductivity and corrosion resistance over repeated insertion cycles.
• Low-profile thermoplastic polyester insulator body provides structural stability while maintaining a compact vertical profile.
• Panel mount installation style with solder pin termination facilitates robust integration into industrial enclosures.

Edgeboard Connectors Applications

• Industrial control systems requiring durable card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement instrumentation panels
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness, material composition, and packaging details. Ensure compatibility with the target PCB thickness of 1.57 mm nominal. Confirm RoHS compliance status and environmental ratings prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for 48-position dual-row connections. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Verify that the host system supports the specified 5 A current rating and operating temperature range of -40°C to +105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common electrical characteristics such as 5 A rating and gold contact plating. The 305 series is widely used in modular electronic designs requiring reliable interconnects.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series family with identical 48-position, dual-row, 3.96 mm pitch specifications. Cross-referencing mechanical dimensions and terminal configurations is essential for equivalent replacement.
