harsh environment ratchet coupling m series connector rapid ratchet coupling mechanism the m series connector offers a new innovative design for motorsport applica tions and military systems. made of high-strength aluminium, this connector is one of the lightest and most compact connector of the lemo range. a ratchet screw system enables quick and secure coupling of the connectors. the arctic grip makes it easy to manipulate the connector while wearing winter gloves or when the connector is located in a difficult to access area. features ? ratchet-coupling mechanism ? quick mating: 1/2 turn to seat ? compact design for space savings ? oil and fuel resistant ? high vibration and shock resistance (gunfire test) ? 360 screening for full emc shielding ? sealed to ip68 when mated ? colour coding / keying ? requires 2x the coupling force to unmate ? scoop proof ? reverse sex configuration possible
