305-066-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-066-520-503 is a standard card edge connector header designed for panel mounting with a vertical orientation. It features a dual row configuration providing 66 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, while the insulator body is made of thermoplastic material.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability status and regional distribution restrictions. Ensure that the required thermal operating range of -40 C to +105 C aligns with the intended application environment. Confirm that the 5 A current rating and 5 GOhms insulation resistance meet the system electrical requirements before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual row card edge connector with 3.96 mm pitch is required for panel mounting. The vertical orientation and 1.57 mm board thickness compatibility define the mechanical fit. Consider the gold-plated copper alloy contacts for corrosion resistance and the thermoplastic housing for durability in standard industrial environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-066-520-503 specifically provides a 66-position dual row configuration. It utilizes a solder pin termination style for permanent mounting to the host panel or chassis structure.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include the 305-048-520-504, 305-040-520-268, and 305-038-520-502. These alternatives share identical 3.96 mm pitch, 1.57 mm board thickness, and 5 A current ratings. Verify that the specific position count matches the design requirements before substitution.
