387-031-542-678

Edgeboard Connectors Overview

The EDAC Inc. 387-031-542-678 is a standard card edge connector from the 387 series, designed for single-edge board applications. It features 31 positions with a 0.156-inch (3.96mm) pitch and accepts PCB thicknesses between 0.054 and 0.070 inches. The connector utilizes female cantilever contacts made of copper alloy with gold plating. It employs a through-hole termination method and includes flanges with threaded inserts for secure mounting. The housing is constructed from black polyester insulation, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Features female cantilever contacts for reliable card edge engagement
• Includes flanges with threaded inserts for panel or chassis mounting
• Constructed with black polyester insulation for durability
• Supports through-hole termination on printed circuit boards

Edgeboard Connectors Applications

• Single-edge card edge interconnections
• Panel-mounted electronic assemblies
• Industrial control system interfaces
• General-purpose backplane connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and flange configuration. Confirm that the threaded insert specification aligns with the mounting hardware available in the target assembly. Ensure the PCB thickness falls within the specified operational range to guarantee proper contact engagement and mechanical stability during installation.

Edgeboard Connectors Selection Notes

Select this component when a single-row, non-specified card edge connector with integrated mounting flanges is required. The 0.156-inch pitch suits applications needing wider spacing than standard 0.100-inch connectors. Consider the through-hole termination and thermal operating range for compatibility with the manufacturing process and environmental conditions of the final product design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 series, which provides standard card edge connectors with various positioning options. The series is characterized by its robust construction and versatile mounting features, including both threaded and unthreaded flange variants. The 387-031-542-678 specifically addresses needs for 31-position connectivity with secure mechanical attachment capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 387-031-542-604 and 387-031-542-103, differing primarily in flange thread specifications. Verify that alternative parts maintain the same 31-position count, 0.156-inch pitch, and through-hole termination style to ensure functional interchangeability without redesigning the mounting structure.
