387-027-542-104

Edgeboard Connectors Overview

The EDAC Inc. 387-027-542-104 is a single-row card edge connector designed for vertical through-hole mounting. It features 27 positions with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes gold-plated copper alloy contacts and a black thermoplastic polyester housing. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). The unit operates within a temperature range of -40°C to +105°C and includes flanges for secure installation.

Edgeboard Connectors Feature Summary

• Single-edge female contact configuration for non-specified card types
• Gold-plated cantilever spring contacts ensure reliable signal transmission
• Flanged design provides flush mounting with top openings for screw access
• Thermoplastic polyester insulation offers thermal stability and durability

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Embedded computing module board-to-board linking
• Test and measurement instrument signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 387 Series Ordering Guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target printed circuit board thickness limits. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 27-position connection is required for vertical mounting applications. Ensure the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm range. Verify that the 3.96 mm pitch aligns with the design layout constraints. Consider the operating temperature range and environmental exposure requirements before implementation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 series of standard card edge connectors. The series is characterized by robust construction suitable for high-reliability applications. Components in this family typically feature gold-plated contacts and thermoplastic housings. The 387-027 variant specifically addresses designs requiring twenty-seven signal or power paths in a single row configuration.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 387 series parts with identical 27-position counts and matching pitch dimensions. Verify mechanical footprint and flange alignment before swapping. Cross-reference with generic industry equivalents only if electrical ratings and physical tolerances are strictly matched.
