857-012-459-108

Edgeboard Connectors Overview

The EDAC Inc. 857-012-459-108 is a standard card edge connector from the 857 series, designed for high-temperature applications. It features 12 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes semi-bellows contact types and tin plating on a single edge configuration. Key physical specifications include a black insulator color and an operating temperature range of -40°C to 125°C. Mounting options include flush mount, top opening, and threaded insert with 4-40 compatibility.

Edgeboard Connectors Feature Summary

• Semi-bellows contact design ensures reliable signal transmission
• High-temperature rated insulator material supports demanding environments
• Versatile mounting configurations including flush and top opening styles

Edgeboard Connectors Applications

• Industrial control systems requiring robust connectivity
• Communication equipment interfaces
• Medical device internal connections

Edgeboard Connectors Procurement Notes

Verify the specific termination row and plating type against project requirements before ordering. Confirm that the 4-40 threaded insert mounting style aligns with the mechanical assembly constraints. Ensure the single-edge readout configuration matches the PCB layout design. Cross-reference the high-temperature rating with the operational environment limits to guarantee long-term reliability and performance stability.

Edgeboard Connectors Selection Notes

Select this component when a single-edge card edge connector with semi-bellows contacts is required. The 0.156-inch pitch suits standard board thicknesses. Consider the flush mount and top opening features for panel integration needs. The high-temperature capability makes it suitable for environments exceeding standard commercial limits. Verify compatibility with existing guide rails or mounting hardware.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors. The series offers various position counts and termination options. The 857 series is characterized by its durability and suitability for high-reliability applications. This specific model provides a 12-position solution within that broader product family.

Edgeboard Connectors Replacement Considerations

Check for direct substitutes within the 857 series with identical pin counts and pitch. Verify mechanical dimensions and mounting hole patterns for compatibility. Ensure electrical ratings and temperature ranges meet or exceed original specifications.
