D2820-01 – HARWIN

Overview

The Harwin D2820-01 is a robust 20-position, open-frame socket designed for secure component termination onto printed circuit boards. Its primary function is to facilitate reliable electrical interconnections for modular or field-replaceable components, offering a critical mechanical interface. A key design consideration for such connectors is the trade-off between contact retention force and ease of insertion/extraction; while high retention is desirable for vibration resistance, it can increase mating cycle wear. The D2820-01 balances these factors through its vertical PCB tail mounting and robust construction, ensuring consistent electrical performance in demanding environments.
