M - Rugged Ratchet coupling
In harsh environments connectors need to be reliable, strong and resistant to vibration. The M series, used in the aerospace, UAV, defence, and motorsport industries, uses a ratchet screw system for rapid and secure coupling. Lightweight and compact yet robust and oil/fuel resistant, the M series is available in a variety of sizes (including miniature), watertight and vacuum-tight models, threaded model compatible with standard MIL-DTL-38999L backshells. The keying system offers high contact density for secure signal transmission, and sensitive signals are protected by 360° EMC shielding. A large selection of insert configurations including high-density low voltage, high power, high-speed, coaxial and fibre optic contacts and as well as hybrid solutions is available.

M Series update: Enhanced coaxial contacts for expanded frequency ranges
We’re pleased to announce significant updates to our M Series offering, providing you with even greater flexibility and performance for your applications
VoidSense - Enhancing Reliability in Railway Track Monitoring
VoidSense uses a linear sensor which is clamped to the body of the device, and this connects to the device via a short length of screened cable and a connector, which was initially an M12-type industrial connector, but these were fiddly, difficult to confirm a positive connection and potentially open to manufacturing issues with screw terminal connections.
LEMO UK to Exhibit at the Engineering Design Show in Coventry
LEMO UK, a leading provider of high-quality connectors and cable assembly solutions, is excited to announce its participation in the upcoming Engineering Design Show, taking place at the Coventry Building Society Arena from October 9th to 10th.
