305-080-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-080-556-208 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 80 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contact plating is gold over a copper alloy base, providing a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high dielectric strength with a voltage rating of 1800VACrms

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing polarized board connections
• High-reliability communication equipment modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 80-position dual-row configuration and 3.96mm pitch before ordering. Confirm that the application environment remains within the specified -40°C to +105°C operating temperature range. Ensure that the PCB thickness adheres to the nominal 1.57mm specification to guarantee proper mechanical engagement. Check for RoHS compliance requirements if applicable to the final assembly standards.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided card edge boards. The dual-row layout supports higher density interconnects compared to single-row alternatives. The inclusion of polarizing key acceptance ensures correct alignment during insertion. Verify that the 5A current rating meets the electrical load requirements of the target circuit design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for industrial and commercial applications. The series offers various position counts while maintaining consistent 3.96mm spacing. The 305-080 variant specifically addresses needs for high-pin-count interfaces in constrained panel spaces.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same family include the 305-070-556-568 and 305-054-556-278, provided the pin count difference is acceptable for the design.
