857-029-559-103

Edgeboard Connectors Overview

The EDAC Inc. 857-029-559-103 is a single-edge female card edge connector from the 857 series, designed for reliable signal transmission in electronic assemblies. It features 29 positions with a 0.156-inch (3.96 mm) pitch and utilizes gold-plated contacts to ensure low resistance and corrosion resistance. The component is constructed with a thermoplastic housing and copper alloy terminals, supporting standard PCB thicknesses. This connector provides a secure mechanical interface for single-sided circuit boards, maintaining electrical integrity across varying environmental conditions while adhering to industry-standard dimensional profiles.

Edgeboard Connectors Feature Summary

• Single-edge female configuration for secure mating with single-sided printed circuit boards
• Gold-plated contact surfaces to enhance conductivity and prevent oxidation over time
• Thermoplastic insulator housing providing structural stability and electrical isolation
• Copper alloy terminal construction ensuring durable mechanical retention and current flow

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Medical device internal board connections
• Consumer electronics module integration

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm exact pin count, plating thickness, and mounting style compatibility. Ensure the target application requires the single-edge variant rather than double-edge alternatives within the 857 family. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row connection is required for boards with a 0.156-inch edge guide width. Confirm that the thermal environment remains within the operating limits of the thermoplastic material. Evaluate the need for gold plating versus tin options based on the expected mating cycle count and exposure to corrosive agents during the product lifecycle.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series, which offers various row configurations and termination styles. The 857-029-559-103 specifically denotes a 29-position single-edge receptacle. It complements other 857 variants that provide double-edge or different pitch options for higher density applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 857-series connectors with identical 29-position single-edge specifications. Verify mechanical footprint and pin pitch compatibility before swapping with generic equivalents.
