There are 28 names in this directory beginning with the letter M.
Male Concentric
A concentric or triaxial contact where the outer contact is male: and the center contact(s) may be male or female. Also referred to as a triaxial contact.

Mass Termination
Method of termination in which terminals that pierce flat cable insulation without stripping, mate with enclosed conductors to form gas tight metal to metal connections.

The joining, engaging, connecting or coupling of two connectors or devices designed to be utilized together.

Mating Face
See Interface.

Mating Hardware
A mechanical device that fastens connector halves together.

Mating or Unmating Forces
The force required to fully engage or separate a plug connector to and from a receptacle connector including the effect of coupling, locking or similar operations. It is the resulting force of all of the contacts assembled to their housings.

One of two component materials that make up a composite. The other is commonly referred to as the reinforcement. It can be a metal, resin, or ceramic material. It holds the reinforcement together to enable the transfer of stresses and loads to the reinforcements.

Maximum Operating Temperature
The maximum ambient temperature at which a connector will operate continuously within specified performance levels.

Measurement System Rise Time
Rise time measured with the fixture in place, without the specimen, and with filtering (or normalization). Rise time is typically measured from the 10% to 90% level.

Metal-to-Metal Bottoming
In cylindrical bayonet connectors, metal-to-metal bottoming is the situation in which the shell surface of the receptacle bottoms (contacts) the inside rear portion of the mating plug. This is achieved by an adjustable ring on the collar of the plug.

Metered Solder Cup
A contact solder cup condition of which the cylindrical portion of the contact to which the wire is inserted is partially filled with a specific amount of solder before assembly of the connector.

A random unintentional microscopic bend of a fiber usually caused by compressive or bending forces applied to the cable or fiber.

The movement or sliding of some metal platings, notably silver, from one location to another. It is felt that this results from a plating action in the presence of moisture and an electrical potential.

Mismatch, Connector Impedance
Terminal or connector having a different impedance than that for which the circuit or cable is designed.

Modified Wrapped Connection
A connection achieved by wrapping a solid conductor around a post in the normal manner with the wire insulation also wrapped around at least three corners of the post.

A modular connector is one in which similar or identical sections can be assembled together to provide the best connector configuration for the application.

Mold, Potting
An accessory used as a form for containing the potting compound around the terminations of a connector. (see BOOT)

Mosquito Clip
A formed copper alloy element, cylindrical in form with converging spring fingers which is pressed into a single contact element barrel and termination tail assembly. The resultant assembly forms an individual contact element which when combined with similar contact elements, all contained in prescribed contact cavities in a socket insulator body, makes up a complete multi-contact socket assembly.

Mother Board
A printed board used for interconnecting arrays of plug-in electronic modules.

Mother-Daughter Board Connector
A board mounted connector designed for interconnection of other printed circuit boards.

Mounting Flange
A projection from a component for the purpose of attaching the component to a rigid surface.

Mounting Hardware
A mechanical device that mounts connector assemblies to a piece of equipment or circuit board.

Cable entrance of a connector barrel.

Multilayer Printed Circuits
Electric circuits made on thin copper-clad laminates, stacked together with intermediate insulation and other circuit sheets, bonded together with heat and pressure. Subsequent drilling and electroplating through the layers result in a three dimensional circuit.

Multimode Fiber
A fiber capable of propagating more than one mode of a given wavelength.

Multiple Conductor Cable
A combination of two or more conductors gathered together and insulated from one another and from the sheath or armor where used.

Mutual Inductance (Lm)
The common property of two electric conductors whereby a voltage (electromotive force) is induced across one conductor by a change of current in the other conductor.

Mutual Inductance Coupling Coefficient (Km)
The measure of degree of magnetic coupling between two conductors. It is a unitless parameter and is defined as follows: NEEDS FORMULA
