305-040-520-508

Edgeboard Connectors Overview

The EDAC 305-040-520-508 is a standard card edge connector header featuring 40 positions with a 3.96 mm pitch and dual rows. Designed for panel mounting at a vertical angle, it accommodates printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy with gold plating to ensure reliable conductivity, rated for 5 A continuous current. It utilizes solder pin termination and operates within a temperature range of -40°C to +105°C, offering an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high insulation resistance of 5 GOhms for signal integrity

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing reliable vertical headers

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating, housing color, and termination style match project requirements. Confirm availability through authorized distributors as supply status may vary. Ensure the selected variant aligns with the required PCB thickness and polarizing key compatibility before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row header is required for vertical panel mounting. It is suitable for applications demanding a 5 A current rating and operation up to +105°C. Verify that the target PCB thickness matches the 1.57 mm specification and that the design supports the necessary polarizing key configurations for proper assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options, all sharing common mechanical features such as panel mount styles and solder pin terminations. The 305 series is widely used in industrial and commercial electronics for connecting edge-board modules to backplanes or chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 40-position, 3.96 mm pitch specifications, such as 305-040-520-502 or 305-040-520-203, provided the housing color and specific termination details meet the design constraints.
