LEMO
Encyclopedia
LEMO is both the name of an electronic and fibre optic connector manufacturer based in Switzerland, and the name commonly used to refer to push-pull connectors made by that company, which are used in medical, industrial, audio/visual, telecommunications, military, scientific research and measurement applications. The company took its name from the company founder, engineer on Mouttet, originally a manufacturer of contacts in noble and rare metals. The best known LEMO connectors are high quality push-pull circular types.

LEMO has set several connector standards, such as the 3K.93C connector for HDTV and 00.250 connector for NIM

The LEMO 00, a miniature push-pull 50Ω coaxial connector, is a standard adopted by the NIM and CAMAC standards used in nuclear and particle physics. It is used as a replacement for BNC connector

s in high density designs, for both analog and fast logic signals.

While LEMO connectors were generally developed as proprietary designs, the legal status of many of the older designs is not clear. For example, the LEMO UK website itself shows a standardisation date of 1970 for the popular LEMO 00 model. Any patent on that design would therefore have expired around 2000 or earlier, depending on the filing date and jurisdiction.

This has enabled other companies to copy the design using published interface details.
