305-058-500-278

Edgeboard Connectors Overview

The EDAC 305-058-500-278 is a standard card edge connector from the 305 Series, manufactured by EDAC Inc. It features a dual-row configuration with 58 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is 3.56 mm. Designed for panel mounting in a vertical orientation, it utilizes solder lug termination. The contacts are made of copper alloy with gold plating, supporting a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The insulator body is green thermoplastic. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure compatibility with required PCB thickness and termination style. Confirm that the 58-position count matches the design requirements. Check RoHS compliance status if restricted substances are prohibited in the target application environment. Ensure panel mounting hardware specifications align with the connector's flange dimensions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for 1.57 mm thick boards. The 5 A current rating suits moderate power applications. Verify that the vertical panel mount style fits the enclosure constraints. Consider the gold-plated copper alloy contacts for reliable signal transmission in industrial environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent 3.96 mm spacing. The 305-058-500-278 specifically provides a 58-position solution for dual-edge cards, fitting into the broader catalog of interconnect solutions designed for durable panel-mounted applications.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for alternative position counts. Verify mechanical fit with existing panel cutouts. Ensure electrical ratings meet or exceed system requirements when substituting.
