M Series
The M Series connector offers a new innovative design for avionics, aerospace, military, security, motorsport and heavy
duty applications.
Made of high-strength aluminium, this connector is one of the lightest and most compact of the LEMO product line.
A one-grip ratchet screw system enables quick and secure coupling of the connectors. The arctic grip makes it easy to
manipulate the connector while wearing gloves or when the connector is located in a difficult to access area.
