LEMO’s M Series Ratchet Coupling Type Connectors
In harsh environments connectors need to be reliable, strong and resistant to vibration. The LEMO’s 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 360Degrees 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.
The M Series connector from LEMO features an innovative design tailored for motorsport applications and military systems. Constructed from high-strength aluminum, this connector stands out as one of the lightest and most compact in the LEMO product line. Its one-grip ratchet screw system allows for quick and secure coupling. The arctic grip ensures easy manipulation, even when wearing gloves or when the connector is in a hard-to-reach area. Regardless of the environment’s severity, LEMO has a ready-to-implement solution for you today.
