305-038-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-038-520-558 is a standard card edge connector header featuring 38 positions with a 3.96 mm pitch. It utilizes a dual-row configuration designed for vertical panel mounting. The contacts are constructed from copper alloy and feature gold plating, supporting a current rating of 5 A. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm. The insulator body is made of thermoplastic material, providing an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge contact design accommodates double-sided PCB traces for increased signal density.
• Gold-plated copper alloy contacts ensure reliable electrical conductivity and corrosion resistance.
• Vertical panel mount style provides secure mechanical attachment to chassis or enclosure panels.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-panel interconnects
• Telecommunications equipment utilizing high-density signal routing
• Automotive electronics modules needing durable environmental sealing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact pin count, row configuration, and termination type. Ensure the target PCB thickness matches the 1.57 mm specification for proper insertion force and retention. Confirm that the operating temperature range meets the environmental requirements of the final assembly application before procurement.

Edgeboard Connectors Selection Notes

Select this component when a 38-position interface with 3.96 mm spacing is required for vertical panel integration. The dual-row layout maximizes connection density within a limited footprint. Verify that the host system supports the 5 A current rating per contact and that the gold plating level satisfies the intended cycle life requirements for mating cycles.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles for card edge applications. The series is characterized by its standardized 3.96 mm pitch and compatibility with standard double-sided PCBs. It serves as a reliable interconnect solution for replacing older legacy connectors in industrial and commercial hardware designs.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series prefix and identical 38-position count. Verify that alternative candidates maintain the 3.96 mm pitch and 1.57 mm board thickness compatibility to ensure mechanical fit without modification.
