305-048-556-558

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-558 is a standard card edge connector from the 305 Series, designed for panel mount applications with a vertical orientation. It features a dual-row configuration providing 48 positions with a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it employs a solder lug termination type. The housing is constructed from thermoplastic material, ensuring durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row card edge design with integrated card guides and extender functionality
• Gold-plated copper alloy contacts ensure corrosion resistance and stable conductivity
• Thermoplastic housing provides structural integrity and electrical insulation
• Vertical panel mount style facilitates secure board-to-board or backplane connections

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with EDAC Inc. before procurement. Confirm that the solder lug termination matches your PCB fabrication capabilities. Ensure the panel cutout dimensions align with the connector's mechanical specifications to guarantee proper fit and strain relief during installation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, high-density connection is required for thick PCBs up to 1.57 mm. The 3.96 mm pitch offers spacing suitable for higher voltage isolation compared to finer pitches. Consider the vertical mounting profile for space-constrained panels where horizontal clearance is limited but vertical depth is available.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series is characterized by its versatility in row counts and position numbers, catering to various industrial and commercial interface needs. The 305-048-556-558 specifically addresses the need for 48-position dual-row connectivity with enhanced mechanical guidance features.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part number 305-048-556-258 if single-sided readout is acceptable, though pinout may differ. Verify mechanical compatibility with any alternative suppliers offering similar 3.96 mm pitch dual-row connectors, ensuring identical contact plating and housing material ratings.
