807-028-424-208

Edgeboard Connectors Overview

The EDAC Inc. 807-028-424-208 is a standard high-temperature card edge connector receptacle designed for reliable signal transmission in demanding environments. This component features a dual-row configuration with 28 positions and a contact spacing of 3.96 mm (0.156 inches). It supports a maximum board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure low resistance and corrosion resistance. The unit employs a Diallyl Phthalate (DAP) insulator, providing robust electrical insulation with a minimum resistance of 5 GOhms. Rated for 5 A current, it operates within a temperature range of -40°C to +125°C. Installation is achieved via through-hole solder pin termination in a vertical orientation.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact tail bend configurations and contact codes. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the vertical installation style aligns with the mechanical layout requirements. Cross-reference the 28-position count and 3.96 mm pitch with system design specifications before procurement.

Edgeboard Connectors Selection Notes

Select this connector when high-temperature operation up to 125°C is required for card edge applications. The dual-row format is suitable for designs needing connections on both sides of the daughter board. Verify that the through-hole mounting style fits the assembly process. Ensure the 5 A current rating meets the electrical load requirements of the application.

Edgeboard Connectors Part Context

This component belongs to the EDAC 807 Series, which specializes in high-temperature card edge connectors. The series offers various position counts and row configurations tailored for rugged applications.
