345-034-542-188

Edgeboard Connectors Overview

The EDAC Inc. 345-034-542-188 is a single-row card edge connector with 34 positions and a 0.100-inch (2.54mm) pitch. It features female copper alloy contacts with gold plating, designed for through-hole termination. The unit accommodates board thicknesses of 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C. The housing is green thermoplastic polyester, and the flange includes top-mount openings with 4-40 threaded inserts.

Edgeboard Connectors Feature Summary

• Single-sided female contact configuration for unidirectional signal transmission
• Integrated mounting flanges with threaded inserts for secure panel attachment
• Gold-plated cantilever spring contacts ensuring reliable electrical connection

Edgeboard Connectors Applications

• Industrial control system backplanes
• Embedded computing module interfaces
• Test and measurement equipment interconnects

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the specified 0.054 to 0.070 inch range to ensure proper contact engagement. Confirm that the mating slot width aligns with the connector's design specifications. Ensure the installation environment remains within the rated operating temperature limits of -40°C to 105°C for long-term reliability.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface with integrated mechanical mounting is required. The 34-position count suits applications needing moderate I/O density without dual-side complexity. The through-hole termination method provides robust mechanical stability compared to surface mount alternatives. Verify compatibility with existing PCB fabrication tolerances before integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse interconnect needs. The specific suffix indicates the single-row variant with flanged mounting options. This series is widely used in industrial and commercial electronics requiring durable, high-reliability connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 345 series single-row connectors such as 345-034-542-203 if dual-row functionality is acceptable. Verify that any substitute maintains the same 0.100-inch pitch and compatible flange dimensions to preserve mechanical fit.
