305-048-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-512 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 48 positions with a 3.96 mm (0.156 inch) contact spacing and accommodates a nominal printed circuit board thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts with a half-beam terminal type for secure mating. Constructed with a thermoplastic polyester insulator body, it supports dual-sided card insertion and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for robust structural integration
• Gold-plated copper alloy half-beam contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides thermal stability and insulation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 48-position count with the system design to prevent pinout mismatches during assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-reliability connection for thick PCBs is required in constrained spaces. The 3.96 mm pitch offers reduced density compared to finer pitches, aiding in manufacturing yield. The vertical orientation simplifies cabling access while maintaining a low profile. Consider the thermoplastic insulation properties for environments requiring stable dielectric performance across wide temperature variations.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for demanding industrial and commercial applications. The series emphasizes durability through metal alloy contacts and robust plastic housings. Variants within the series differ primarily by position count and mounting style, providing scalable solutions for various board sizes and interface densities.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 48-position counts and 3.96 mm pitch. Verify that alternative parts maintain the same vertical panel mount configuration and compatible PCB thickness tolerance. Ensure equivalent current ratings and temperature ranges are met by any cross-brand replacement.
