HDMI Connectors - Type A, B, C, D, Due east (mini-HDMI & micro-HDMI)
HDMI uses 5 main connector types: Type A, B, C, D, and E, each for different applications - these include the standard connector as well as the mini-HDMI and micro-HDMI.

There are five types of HDMI connector. Although the main type seen on televisions and other domestic AV equipment is the most widely used, and probably the near robust, other types exist for other applications too.
The most common HDMI connector is the type A connector and along with the Blazon B, these were launched with the initial standard. Other types take been introduced since so to come across specific needs.
The HDMI system and the accompanying connectors and leads are able to enable the high speed transfer of high quality and bandwidth AV signals along with providing for other associated capabilities. The connectors are manageable whilst remaining robust and reliable.
In many respects some HDMI connectors await quite similar to USB connectors. However there are differences in size and particularly the number of wires in the cable and connector. HDMI connectors & cables have 19 wires / connections and this is significantly more than than the USB connector.

HDMI connector types
The different HDMI connector types have remained unchanged after their introduction. This has enabled backwards compatibility to exist maintained over the life of the standard.
With the exception of the dual link Type B connector, they all have 19 pins enabling the standard to remain the same beyond all connector types.
In view of the unlike sizes, the dissimilar HDMI connectors tend to be used on dissimilar types of equipment.
Summaries of the unlike HDMI connector types are given below:
HDMI Type A connector: This connector was launched with the original standard and has been the mainstay of the HDMI standard since then. The Blazon A connector is the 1 that is the most familiar to users of AV equipment and it is constitute on a huge number of items from televisions, DVD players, satellite boxes, recorders, games consoles and many more than items. Where space is non an event, the Type A HDMI connector is ideal as information technology is the most robust.
The plug or male person connector has exterior dimensions of 13.9 mm × 4.45 mm, and the receptacle or female connector has inside dimensions of 14 mm × 4.55 mm.
HDMI Type A Connector Diagram There are 19 pins and the bandwidth is able to carry all SDTV, EDTV, HDTV, UHD, and 4K modes. This connector type is electrically compatible with single-link DVI-D.
The male version of the HDMI Blazon A connector is widely available on ready made leads as well as connectors for self assembly. Many of the female versions are also available for incorporation into AV equipment. There is a good selection, so the one with the required dimensions, format and specification can be chosen.
HDMI Blazon B connector: This type of HDMI connector was also launched with the original standard in 2002 and it is aimed at carrying dual link DVD-I video. The connector has never been used in products because with the introduction of HDMI 1.3, the speed of a single link exceeded that of the quondam dual link. Equally the connector is larger than the single link standard manner, there has been no reason for its apply. Withal it is still retained within the specifications.
This blazon of HDMI connector measures 21.2 mm × 4.45 mm and has 29 pins, carrying six differential pairs instead of three.
HDMI Blazon C connector - Mini-HDMI connector: This is the mini-HDMI connector and is smaller than the Blazon A connector, measuring 10.42 mm × 2.42 mm but however retaining the 19-pin configuration. The mini-HDMI retains all the functionality of the larger HDMI Type A, but the connector is much smaller.
The HDMI mini connector was introduced in HDMI Version 1.iii as the HDMI standard became more widely accepted and the need for a smaller connector was recognised.
Mini-HDMI connector There are differences in the mini-HDMI connector connection configuration: all positive signals of the differential pairs are swapped with their corresponding shield, the DDC/CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pivot fourteen instead of pin 13, and the reserved pin is 17 instead of pivot 14.
The HDMI Type C connector tin be connected to a type A connector just it requires the use of a type A-to-blazon C cable or an adapter.
The mini-HDMI connectors are very common on many pieces of portable equipment. Some examples include: DSLR cameras, camcorders, larger tablets, sat nav systems and the like.
HDMI Type D connector - micro-HDMI connector: The size of the HDMI Type D connector is very similar to the micro-USB connector and as a upshot the Type D is ofttimes known as a micro-HDMI connector. Micro-HDMI connector The measurements are only 6.4 mm × 2.8 mm and within this outline the micro-HDMI retains the nineteen pins of the other connectors, although the pivot assignments are dissimilar. The micro-HDMI connector was introduced with HDMI Version 1.iv. It was adult specifically for audio-video connectivity in small and portable devices similar mobile phones.
HDMI Blazon E connector: The Type E HDMI connector is aimed at automotive applications. This connector was introduced with HDMI Version 1.4.
In club to preclude it vibrating loose it incorporates a locking tab and as well a crush to help forestall dirt and moisture from entering. Additionally a relay connector is bachelor for connecting standard consumer cables to the automotive ones and enabling an interface to consumer AV items which is happening increasingly.
Female and male HDMI connectors
At that place is a convention for connectors that the source of power, data, audio etc has a female connector and the item taking the power, audio, etc is male. The reason for this is that the female connector pins, by the very nature of a female connector are protected and cannot suffer a brusque excursion past the accidental shorting by an external metallic object.
Withal many mod connectors also accept male areas that are protected and in that location is less gamble of short circuits.
Accordingly female HDMI connectors are usually built into both the static devices at either end of the connection, due east.chiliad. a Tv set or display, and a computer , DVD, etc. In other words female HDMI connectors are nowadays on the indicate source device and the receiving device. Male person HDMI connectors are then attached to both ends of the connecting cables.
Function of the reason for this is that many of the communications occur in both directions and therefore, fifty-fifty though one may exist a signal source equally such, the receiving device nevertheless sends signals and other data out. Every bit a result is is sensible to prefer the strategy that the devices have female connectors and the cables take male HDMI connectors.
Normally the female HDMI connectors are recessed into the body of the various devices but even so they tend to exist damaged more easily as a consequence of the strain sometimes practical accidentally if the cables are pulled in the incorrect management, etc. Every bit a result, the female person HDMI connectors tend to exist sold more frequently as replacement connectors!
Even if male connectors on a cable are damaged on the shorter commercially made HDMI cables, the difficulty of replacing them and the cost of the connector compared to a new HDMI cable means that a new HDMI cable is bought rather than trying to attempt a repair.
Straight & right angled HDMI connectors
The almost obvious format for a connector is to take i that, when plugged in to the receptacle, the cable from the free connector extends outwards from the connection. This is suitable for most applications, just information technology can require some space for the cablevision to bend to the direction in which information technology needs to be routed.
At that place are some instances where a very sharp curve might exist needed. This bend might need to exist besides precipitous to exist accommodated by the HDMI cable. This could put also much strain on the HDMI connector and cable.
Right angles HDMI connectors are very useful where equipment may be close to a wall or panel inside a chiffonier, etc. The cable coming out of the connector will travel alongside the equipment and not require a very abrupt bend to enable it to fit within the space available.
If an HDMI cable with a correct angled connector is not available, so right angled adaptors are available. These should by and large not exist used unless necessary as they add a further connection into the cabling, and will not be as firm every bit a unmarried HDMI connector, merely they nevertheless resolve an upshot and tin can exist used for the short term.
HDMI connector adapters
In that location are many cables that enable HDMI Type A connections to interface with mini-HDMI or microHDMI. These cables are widely available and will exist able to provide the full HDMI capability, consistent with the adequacy of both ends of the link.
HDMI connector adapter set
These cables are very useful because they practice not require the use of an HDMI connector adapter, and a cable is required anyway to link the two items together.
There are some instances where a connector adapter may exist needed. It can exist especially useful to accept a fix of HDMI adaptors to link Type A to mini-HDMI or micro-HDMI connectors when setting up systems when the correct cables may not exist available.
The diverseness of HDMI connectors ensures that the HDMI standard can be successfully used in many unlike areas and they tin can accommodate the requirements of users of the many unlike applications for which HDMI is used.
