SMC (SubMiniature version C) connectors are coaxial RF connectors developed in the 1960s. They use a #10-32 UNF threaded interface (screw type). They offer excellent electrical performance from DC to 10 GHz. Female SMC connectors have a pin for the center contact, and male SMC connectors have a socket for the center contact, and are therefore analogous to the "reverse polarity" versions of other types of RF connectors

Since TNC series have a screw type design using the BNC series combining system, they can be used appropriately for mechanics having especially strong vibrations. They have 50ohm and 75ohm impedances. Frequencies up to 11GHz can be used for 50ohm connectors while 75ohm connectors can be used up to 1GHz. Cable connectors are divided by clamp or crimp according to their usage and every 75ohm and 50ohm TNC connectors can be used compatibly.

Sub Microminiature connectors
“Push-pull” snap-on mating

The MCX series connector utilizes the SMB connector series electrical line and has a particularly simple and compact interface 30% smaller than the SMB, the MCX series helps to miniaturize equipment, optimize printed circuit board layouts with its range of models for PCBs and lowers wiring connection costs through its "crimp-on" versions. The excellent electrical characteristics of this seies make it particularly suitable for both civil and military radio communications market.

The SSMA connector is essentially a smaller version of the SMA. It was originally designed for use with .085 semi-rigid cable. The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR.

SSMB series provides excellent electrical performance in a microminiature footprint. While the snap-on mating interface allows quick installation and dense packaging, the excellent electrical performance of the SSMB series allows it to be used in many applications as an alternative to larger connectors like SMAs.

The SSMC connectors ideal for limited-space applications that require the security of a threaded coupling mechanism. They are best used with semi-rigid cables or miniature flexible cables in demanding applications.

The SMP interface is a subminiature interface in the same scale as MMCX connectors but offers a frequency range of DC to 40 GHz. It is commonly used in miniaturized high frequency coaxial modules and is offered in both push-on and snap-on mating styles.

The interface is an excellent choice for PC board to board interconnects. For these applications, the interface series offers an interesting solution by utilizing a male connector on each of the PC boards and a female-to-female adapter mounted in between to complete the connection. The female adapter is often called a bullet and is necessary to provide a flexible link between the male connectors. This flexible link allows .020 inches of radial float and .010 inches of axial float. Typically, one male connector will be specified as a snap on interface and the other as a push on. This ensures that the bullet adapter remains fixed in the same male connector if the PC boards are separated. The bullets are available in multiple lengths to allow for different board spacing.

In its snap-on configuration, the SMP interface is available in two levels of detent each with different mate and de-mate forces. The two levels are full detent and limited detent. In board mount applications, the lower level of detent (limited detent) is typically selected, as it is only required to retain the bullet. Full detent is often used for discreet cable connections where higher forces are desirable.

The SMZ connector features the 75 ohm impedance of the Mini-SMB connector brought up to the size of the standard 50 ohm SMB.

The SHV (safe high voltage) connector is a type of RF connector used for terminating a coaxial cable. The connector uses a bayonet mount similar to those of the BNC and MHV connectors, but is easily distinguished due to its very thick and protruding insulator. This insulation geometry makes SHV connectors safer for handling high voltage than MHV connectors, by preventing accidental contact with the live conductor in an unmated connector or plug. The connector is also designed such that when it is being disconnected from a plug, the high voltage contact is broken before the ground contact, to prevent accidental shocks. The connector is also designed to prevent users from forcing a high voltage connector into a low voltage plug or vice versa, as can happen with MHV and BNC connectors.

A blind mate connector(BMA) is differentiated from other types of connectors by the mating action that happens via a sliding or snapping action which can be accomplished without wrenches or other tools. They have self-aligning features which allows a small misalignment when mating.

Usage : Electrical blind mate connectors provide power or signal and are distinguished from other connectors in that they do not feature a rigid mechanical retention mechanism belonging to the interface itself, such as a threaded coupling nut on an SMA connector. They are typically used in a multi-pin arrangement between racks and panels, daughtercard to backplane, or similar applications where the connector is not mated by itself, but rather by the action of inserting the entire unit or module.

Types
RF : Blind mate RF connectors are generally intended to be used without wrenches or other tools, but can come packaged in a multiport configuration that includes mounting hardware or provided as inserts in a circular connector such as a MIL-DTL-38999. Some examples of blind mate RF interfaces include BMA (OSP), BMMA (OSSP), SMP, and SMPM.

Certain styles of blind mate RF connectors feature a detent or undercut to allow for the mating connector to snap into, improving retention. These styles are typically used when the mate is a cable connector and might see a significant force that would normally demate the connection.

Other configurations feature a smooth bore in which the mate simply slides into to connect. These arrangements are more commonly found in board to board connections, where they are mated with a female to female "bullet" adapter, and no significant force is present to demate the connection.

Optical: Optical signals can also be connected using blind mate connectors providing the capability to link fibre optics on a plug-in card to an optical backplane, or through an optical midplane
