305-046-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-568 is a standard card edge connector from the 305 series, designed for dual-row applications with 46 positions. It features a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts that are gold-plated, it provides a continuous current rating of 5 A and withstands 1800 VACrms. The unit utilizes a solder pin termination type and is intended for panel mount installation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Utilizes half-beam contact type with gold plating for reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density interconnects
• Industrial control systems utilizing standardized card edge interfaces
• Equipment requiring polarized connection for error-proof mating

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm insulation color and flange characteristics, as these attributes vary within the 305 series. Confirm RoHS compliance status against the latest manufacturer documentation before integration. Ensure the receiving facility handles the component according to its material specifications. Cross-reference the datasheet drawing for precise mounting hole dimensions to guarantee mechanical fit within the target enclosure design.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with 46 positions is required for .062-inch thick PCBs. The 3.96 mm pitch suits applications needing robust mechanical retention without excessive board space consumption. Consider the 5 A current rating for power distribution needs within the connector limits. Verify that the panel mount style aligns with the system's structural requirements and that the vertical orientation fits the available chassis depth.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are engineered for durability and precise alignment in industrial environments. The series supports various position counts and termination styles, allowing for flexible system design. The 305-046-521-568 specifically addresses the need for a mid-range position count with standard panel mounting capabilities, serving as a reliable interface between backplanes and daughter cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-048-520-568 or 305-044-521-568, which share identical pitch and mounting characteristics but differ in position count. Verify that any alternative maintains the same 46-position requirement or adjust the design accordingly. Ensure the replacement retains the gold-plated copper alloy contact specification for equivalent electrical performance.
