An outstanding portfolio for exceptional service

Quality, robustness and reliability

Due to the outstanding quality, robustness and reliability of our solutions, LEMO enjoys an unmatched reputation worldwide.

Precision, performance and durability

Driven by Swiss Made precision, in addition to our extremely wide-ranging selection of off-the-shelf products, we specialise in providing long-lasting solutions engineered to suit any specific application, including those subjected to the harshest environments found on Earth and beyond.

Worldwide reach

Relying on a global network of local subsidiaries and distributors, customers anywhere in the world can benefit from the same unmatched technical expertise of the LEMO Group’s leading technical advisors, as well as from our full inventory of products.

Market leader

Internationally recognised as a market leader, the original iconic Push-Pull connector set a  new standard. Patented by Léon Mouttet, LEMO’s founder, the Push-Pull latching system marked a revolutionary invention in connector technology.

Over the decades, the Group has introduced a multitude of innovations and extended its know-how to cables. LEMO has become a global benchmark for high performance interconnect solutions used in demanding applications thanks to its outstanding quality.  Few companies can claim to have directly contributed to a technological revolution. The LEMO Group has had the chance to initiate more than one. In addition to the Push-Pull system, it also set the global standard for hybrid fibre optic connectors supporting the move to HDTV. 

Custom interconnection solutions ready to meet your requirements


LEMO’s broad, innovative and modular portfolio includes 90,000 off-the-shelf connectors and 20,000 associated qualified components, so that different configurations can meet the most specific customer requirements. Our customers can rely on the long-term availability of products, with no risk of phasing-out or obsolescence. As well as LEMO’s leadership in the design and manufacturing of high-performing connectors, the complete interconnection solutions we provide also benefit from state-of-the-art flat, retractable or technical cables and wires designed and manufactured under LEMO’s own brand NORTHWIRE.

Vertically integrated ecosystem
Our total independence, an asset for our clients


Founded in Switzerland in 1946, the LEMO Group has always been able to maintain full control over its business, with the aim of ensuring high quality and performance of its solutions. Such stability is what ultimately enables LEMO to successfully build long-term partnerships and ensure consistent customised support.
