305-084-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-278 is a standard card edge connector featuring 84 positions arranged in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing with a 0.140-inch (3.56 mm) row spacing. Designed for panel mount installation, the unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are gold-plated copper alloy, providing a continuous current rating of 5 A and an insulation voltage of 1800 VACrms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified double-sided card edges
• Low-profile insulator body constructed from green thermoplastic polyester
• Accepts between-contact and in-contact polarizing keys for secure positioning
• Semi-波纹管 contact type ensures reliable electrical engagement

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control board connections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange characteristics and termination style. Confirm the insulation material and operating temperature range align with the target application environment. Ensure the PCB thickness falls within the specified acceptance window to guarantee proper mechanical retention and electrical performance during operation.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for panel mounting applications. The 3.96 mm pitch supports substantial I/O counts while maintaining compatibility with standard board thicknesses. Consider the 5 A current rating and 1800 VACrms insulation strength for robust signal and power distribution needs in industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to suit different density requirements. Components in this family share common design principles, including low-profile bodies and durable gold-plated contacts for long-term reliability in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-048-520-268 or 305-014-521-202 if different position counts are needed. Verify that any substitute maintains the same 0.156 inch pitch and dual-row architecture to ensure mechanical fit.
