305-058-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-268 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 58 positions with a dual female contact configuration and a 3.96 mm (0.156 inch) contact spacing. The row spacing measures 3.56 mm (0.140 inch). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. The insulator body is green thermoplastic polyester. Operating temperature ranges from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact panel integration
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing standardized PCB modules
• Communication equipment housing modular circuit cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating thickness, termination style, and insulator color. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm compliance with relevant environmental directives such as RoHS before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for vertical panel mounting. The 58-position count suits applications needing moderate I/O density. Verify that the 5 A current rating and 1800 VACrms dielectric strength meet the system's electrical requirements. Consider the low-profile body height for space-constrained enclosures.
