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.
