Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact pin count, row configuration, and termination type. Ensure compatibility with the target PCB thickness of 0.062 inches. Cross-reference the RoHS status and material composition with the latest datasheet to meet regulatory requirements for your specific assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required for 12-position signal routing. The 0.156-inch pitch accommodates standard board layouts, while the vertical mounting style suits panel-integrated designs. Consider the 5 A current rating and wide temperature range for robust industrial environments requiring durable thermal plastic construction.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series provides various position counts and mounting options, maintaining consistent 0.156-inch spacing across models.
