305-080-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-080-555-278 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 80 positions with a 0.156-inch (3.96mm) pitch and supports board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with semi-bellows contact types and solder lug termination. It is rated for 5A current and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with gold-plated semi-bellows contacts for reliable signal transmission
• Panel mount design with flush mounting flange featuring top opening and threaded inserts
• Constructed with green thermoplastic polyester insulation for environmental stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing dual-edge card architectures
• Medical devices needing stable high-density connections in constrained spaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange and termination specifications. Confirm that the required board thickness falls within the specified 0.054 to 0.070 inch range. Check RoHS compliance status if restricted substances are a concern for your assembly process. Ensure compatibility with existing panel cutouts due to the specific flange geometry.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96mm pitch is required for panel installation. The 80-position count suits applications needing moderate density without excessive height. Consider the semi-bellows contact type for superior retention force compared to standard fingers. Verify that the operating temperature range meets the environmental demands of the final enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles to accommodate different PCB designs. The 305 series is characterized by its durable construction and consistent performance across industrial and commercial sectors, providing a standardized solution for edge-board interfacing.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-080-555-568 or 305-080-555-268, provided they match the exact pin count and termination style. Always cross-reference the mechanical drawings to ensure flange dimensions and hole patterns align perfectly with the host panel before substitution.
