in medical connectivity
Innovative solutions from design to patient
LEMO’s solutions seamlessly integrate into the medical ecosystem, ensuring excellence and reliability at every stage of the value chain.
Demanding medical conditions
require exceptional solutions
Medical environments are among the most demanding settings for electronic components. From emergency rooms to MRI suites, meeting the highest standards for medical safety and performance. Because failure is not an option, connectors must withstand the harshest medical environments.
Designed for demanding environments — such as high magnetic fields or high-voltage applications — LEMO connectors ensure flawless signal integrity and secure latching, where even the slightest accidental disconnection is not an option.
LEMO connectors ensure fail-safe, rock-solid connection reliability and signal integrity under all conditions, to eliminate accidental disconnections.
LEMO delivers tailored connectivity solutions to meet even your most specific design and performance requirements — for seamless integration into any medical device.
LEMO connectors are fully sterilizable (Steam, Gamma, EtO) following the protocols and tests in line with ISO 11134 and IEC 60601-1 standards. When sterilization is not protocoled, LEMO proposes a wide array of single-use connectors.
LEMO connectors are intuitive and easy to use. Push-pull latching systems combined with an extensive selection of colors and keyings ensure a failsafe connection and prevent mishaps.
Widely used in FDA-approved and globally certified devices, LEMO solutions offer strong compliance assurance for medical designs.
