387-082-555-812

Edgeboard Connectors Overview

The EDAC Inc. 387-082-555-812 is a dual-edge card edge connector designed for high-density interconnect applications. It features 82 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch. The connector utilizes female copper alloy contacts with gold plating and a thermoplastic polyester housing. Rated for 3 A current, it supports PCB thicknesses of 0.054 to 0.070 inches and operates between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates double-sided circuit boards for increased signal density.
• Gold-plated cantilever spring contacts ensure reliable electrical connection and durability.
• Side-mount flanges provide secure panel attachment with unthreaded mounting openings.

Edgeboard Connectors Applications

• High-density backplane interconnects
• Industrial control system modules
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 337/387 Series Ordering Guide to confirm contact termination type and flange specifications. Ensure the selected variant matches the required PCB thickness range and mounting orientation. Cross-reference the manufacturer part number with distributor catalogs to confirm RoHS compliance status and availability before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is required for 0.156-inch pitch applications. Confirm that the target printed circuit board thickness falls within the specified operational range. Evaluate the need for side-mounting versus top-mounting based on chassis constraints. Verify that the 3 A current rating meets the electrical requirements of the connected signals.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 Series, a line of standard card edge connectors known for robust mechanical performance. The series offers various position counts and row configurations to suit different density requirements. The 387 model specifically addresses applications requiring reliable connections in industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 337/387 Series Ordering Guide for direct substitutes with identical pin counts and spacing. Verify compatibility with existing PCB footprints and mounting hole patterns before switching to alternative part numbers from the same family.
