Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm pin count, termination style, and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the dual-edge female configuration aligns with the mating card requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a 0.156-inch pitch is required for dual-edge applications. Consider the 64-position capacity for moderate density needs. Verify that the vertical panel mount style fits the enclosure constraints. Ensure the operating temperature range meets the environmental demands of the specific deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the EDAC standard card edge connector family, characterized by precise dimensional tolerances and durable materials. The 857 series specifically targets applications requiring reliable dual-edge connections with standardized spacing. It serves as a critical interface element in modular electronic systems where consistent signal integrity is paramount.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 857 series or equivalent 0.156-inch pitch connectors from other manufacturers. Verify identical row spacing, board thickness acceptance, and contact configuration to ensure mechanical and electrical interchangeability without redesigning the host assembly.
