857-027-559-103

Edgeboard Connectors Overview

The EDAC Inc. 857-027-559-103 is a standard card edge connector from the 857 series, designed for single-edge board applications. It features 27 positions with a 0.156-inch (3.96 mm) pitch and a 0.200-inch (5.08 mm) row spacing. The connector utilizes gold-plated copper alloy contacts housed in a black thermoplastic body. It supports panel mount installation at a right angle, accommodating boards with a thickness of 0.054 to 0.070 inches (1.37 to 1.78 mm).

Edgeboard Connectors Feature Summary

• Single-edge female connector design for reliable signal transmission.
• Gold-plated contacts ensure corrosion resistance and low contact impedance.
• Right-angle panel mount configuration facilitates compact system integration.

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects.
• Communication equipment backplanes.
• Consumer electronics assembly.
• Medical device circuitry.

Edgeboard Connectors Procurement Notes

Verify that the target application requires a single-edge connector rather than a double-edge variant. Confirm the PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical retention. Check for RoHS compliance requirements if operating in regulated regions. Ensure the right-angle orientation aligns with the chassis layout constraints before finalizing the order.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface is necessary for space-constrained designs. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the right-angle form factor for efficient vertical stacking or side-access connections. Verify that the thermal and electrical ratings meet the specific circuit demands without exceeding the maximum operating temperature limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series, which specializes in single-edge card edge connectors. The series provides various position counts while maintaining consistent 3.96 mm pitch specifications. These connectors are engineered for durability in demanding environments, offering stable performance across a wide temperature range suitable for industrial and commercial deployments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting styles or housing colors. Cross-series replacements require matching the 3.96 mm pitch and 27-position count. Verify that any alternative maintains the same right-angle panel mount configuration and compatible PCB thickness tolerance.
