Unlike automotive connectors, which focus on handling vibration, wide temperature ranges, and high voltage, medical device connectors face the core challenges of "safety" and "purity": ensuring absolute reliability under harsh conditions such as frequent sterilization and contact with bodily fluids, while preventing electrical harm to patients or triggering allergic or rejection reactions. Their key applications revolve around three main scenarios: life support and diagnosis, surgery and treatment, and implantation and wearable devices, each with distinctly different requirements for connectors.

Mainstream brands include: LEMO, ODU, Fischer, Molex, TE Connectivity, Hirose, and AVIC Optoelectronics.
