Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified partners. Confirm RoHS compliance status and REACH registration details prior to procurement. Check for recent Product Change Notifications (PCN) regarding material or manufacturing updates. Ensure supply chain availability aligns with project timelines, as lead times may vary. Validate that the specific ordering suffix matches the required pin count and termination style for the target application.

Edgeboard Connectors Selection Notes

Select this model when high-temperature resistance is critical for the application environment. The 70-position configuration suits dense interconnect needs on dual-edge cards. Verify that the host PCB thickness falls within the specified acceptance range. Consider the right-angle panel mount orientation for space-constrained enclosures. Ensure the 5 A current rating meets the electrical load requirements of the connected circuits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of standard card edge connectors. The series is characterized by its robust construction and suitability for demanding environments. The 857 series offers various position counts and termination options, providing flexibility for different board densities.
