305-044-500-278

Edgeboard Connectors Overview

The EDAC 305-044-500-278 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features a dual-row configuration with 44 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission. The insulator body is made of thermoplastic material, supporting operation within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, row configuration, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the required polarizing key type matches the connector's acceptance specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 44 positions is required. The 3.96 mm pitch and 1.57 mm board thickness compatibility define the mechanical constraints. Consider the 5 A current rating and 1800 VACrms voltage capability for electrical safety margins. Verify that the vertical panel mount style aligns with the enclosure design requirements and that the operating temperature range suits the environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations while maintaining consistent mechanical dimensions and electrical ratings. The 305-044-500-278 variant specifically provides a 44-position dual-row layout. This series is widely used in applications demanding reliable high-density interconnects with standardized form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 44-position dual-row configuration, 3.96 mm pitch, and 1.57 mm board thickness. Verify identical mounting style and electrical ratings. Consult EDAC documentation for cross-referenced part numbers or updated series revisions that maintain functional equivalence.
