M Series Ratchet Coupling Connectors

LEMO M Series Ratchet Coupling Connectors provide a screw coupling system that enables a quick, secure coupling of the connectors for high vibration environments. When mated, these connectors are watertight to 2 meters for 15 hours, achieving an IP68 rating. The plugs come with two grip designs: a standard knurl grip or an arctic grip to allow secure mating while wearing gloves. Receptacle styles include jam-nut or flange panel mount with crimp contacts, PCB pins, or in-line cable mount shells. The M series delivers 360° shielding and high shell conductivity to ensure excellent EMI protection. The overmold feature provides additional strain relief, ensuring cable mount reliability. LEMO M connectors are designed for energy, alternative energy, industrial automation, performance automotive, and other harsh environment applications that require robust performance in a lightweight and compact size.
