857-026-525-107

Edgeboard Connectors Overview

The EDAC Inc. 857-026-525-107 is a standard card edge connector from the 857 series, designed for single-edge board applications. It features 26 positions with a 0.156-inch (3.96 mm) contact pitch and a 0.200-inch (5.08 mm) row spacing. The connector utilizes gold-plated contacts on a copper alloy base to ensure reliable signal transmission. It is rated for vertical panel mount installation and supports a maximum PCB thickness of 0.062 inches (1.57 mm). The housing is black, providing visual identification and environmental protection for the internal contacts.

Edgeboard Connectors Feature Summary

• Gold-plated contacts provide corrosion resistance and stable electrical performance
• Vertical mounting style facilitates secure panel integration
• Single-edge design accommodates standard non-specified card types

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating thickness and housing color variants. Ensure the target PCB thickness does not exceed the 0.062-inch limit for proper mechanical retention. Cross-reference the 26-position count with the required signal routing density before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical, single-edge connector with 26 positions is required. The 0.156-inch pitch suits general-purpose digital signals. Consider the 857 series if higher durability or specific environmental ratings are needed compared to standard series. Confirm compatibility with the mating card edge thickness and width specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors. The series offers various position counts and mounting styles. The 857-026 variant specifically addresses needs for moderate-density connections in vertical configurations. It complements other EDAC products like the 357 and 846 series for diverse application requirements.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify pinout and dimensional compatibility if considering alternative manufacturers. Check for equivalent RoHS compliance status and contact material specifications.
