305-046-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-508 is a standard card edge connector header featuring 46 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch with a 3.56 mm row spacing. Designed for panel mount installation at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector employs solder pin termination methods. The housing is made of thermoplastic material, providing an insulation resistance of 5 GOhms and supporting operation within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided PCBs for high-density interconnect applications.
• Gold-plated copper alloy contacts provide durable electrical performance and corrosion resistance.
• Vertical panel mount style ensures secure mechanical fixation and standardized board alignment.
• Thermoplastic insulator body offers robust dielectric strength and thermal stability.

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 46-position dual-row configuration and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this model when a high-current 5 A rating and gold-plated contacts are necessary for reliable signal integrity. The vertical panel mount orientation is suitable for chassis-based systems requiring direct board insertion. Consider the thermoplastic housing properties for environments demanding stable insulation resistance up to 5 GOhms across the specified operating temperature range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its .156 inch pitch options and robust construction for industrial-grade applications. Similar models in the lineup vary primarily by position count and termination style, sharing common mechanical dimensions and material specifications for interchangeability within system designs.

Edgeboard Connectors Replacement Considerations

Cross-reference alternative suppliers for equivalent 46-position dual-row connectors with identical 3.96 mm pitch and 1.57 mm board thickness acceptance. Verify that substitute parts maintain the same vertical panel mount profile and gold-plated contact specifications to ensure functional equivalence without redesigning the host enclosure.
