The development of M12 connector

 

M12 connector is known by people no matter in any field, the difference between their understandings is just the method or the field difference.M12 connector is very important to our automotive devices, electrical equipment and so on. But when we use the connector, maybe we don’t pay our attention to the connector development. On our Signal opinion, M12 connector will develop in these directions: Intelligence, miniaturization and high frequency, high-speed transmission.
Intelligence
The development of intelligence is important to every fields and the related products. As people need, it must develop in this field, and it can also improve the connector performance.
Miniaturization and high frequency
As the science need, we wish this product could be more small and conveniently to take out. This means they will develop into the miniaturization and high frequency.
High-speed transmission

We have to commit that if it can be used in more fields, we should promise this connector has the high-speed transmission, and then it will get a good feedback from the customer.

Basic connector components

A connector is a relatively simple device with just a few essential parts.

CONDUCTORS
Conductors carry electric current or optical energy. Some uses discrete, or separate, copper wires, but other conductor styles are common. Conductors attach (terminate) to terminals, which are inserted into housings.

TERMINALS
Terminals are the conductors in a connector. When connectors mate, the terminals make contact to bridge the circuit.

Although they appear simple, terminals are precisely designed and manufactured to optimize electrical and mechanical performance over the life of the connector.

Terminals are also called contacts. They are identified as either male or female.

HOUSING
The housing is the connector body or casing. Most connector have a matched pair of housings. Various plastics are used for their insulating property and ability to be molded. The housing provides the mating function, holds the electrical contacts, and protects them from contaminants and electrical interference.

OTHER FEATURES
Connector housings and terminals may include a variety of additional features. For example, the model shown here has a latch to keep the connectors mated. You will learn about other features shortly. For now, realize that they are all designed to support the connector's electrical function by providing mating security and an efficient and reliable electrical interface.

Housing Features

Housing features—mating security In some cases friction between housings may be adequate. More often, connectors employ a locking mechanism to secure the interface against vibrations and other stressors. Some applications are very stable and require minimal locking, But imagine the stress under the hood of a car or the mating security needed on an airplane electrical system or in medical life-support equipment. The locking feature provides that security.   Housing features—polarization To make sure connector pairs align and mate properly, connectors usually employ any of several polarization techniques. Polarization is a mechanical feature of a connector that assures proper mating alignment. The insides of the cavities have a specific shape, and the outsides of some cavities are rectangular and others are beveled.   Housing features—keying Keying provides a function similar to polarization—to assure correct pair mating.   Housing feature—guidance Guidance aligns connector pairs properly before mating. The connector on the right shows a typical approach used with backplane connectors. A metal guide post with a beveled tip is integrated into the housing, or may be incorporated as a optional module. The post aligns with a bushing on the other connector. There may be a post on one connector end or both. Backplane connectors typically have very high circuit counts and can require significant force to mate. Strong metal guide posts keep the connectors aligned under that pressure to prevent damage to pins.   Housing features—mating capture Properly aligning two mating connectors can be a challenge in locations that are hard to see or difficult to reach, such as inside a vehicle dashboard. Blind mating designs facilitate mating with a large flange that funnels one connector into another for accurate alignment before mating. This technique also speeds mating, which can be important, for example, on fast-moving assembly lines.   Housing features—sealing Some connector housings are sealed to protect terminals and electrical connections from moisture and other contaminants. Obvious candidates for sealed connectors include marine and some automotive sub-systems, such as underhood and underbody.

The use of M12 connector

The M12 connector, which has proven itself in industrial applications, is also a top performer in outdoor applications. The use of specific materials makes this possible.

 

Industrial environments would be unimaginable without the classic M12 connector. Data, sensor and power applications are all mastered by the M12. The connector's manufacture relies on well-known materials and production processes: die-casting, injection molding and turning technique all enter the picture.

 

Increased flexibility and the decentralization of facilities are associated with a growing need to also deploy connectors in harsh environments, as well as outdoors. Today, connectors are expected to feature adequate encapsulation against salt spray and mist, which in turn requires more resistant materials.

 

Consequently, this has demonstrated that the M12 connectors are robust and suitable for scenarios in the harshest of environments.Though M12 connector is used in many fields,we still insit that the quality of the M12 connctor is prior.

Knowledge of the industrial connector

Waterproof connectors, waterproof cable, in fact, they are working for a water waterproof electronic components, which can be placed inside the power cord, network cable, etc., not only can provide normal and safe and reliable power supply, signal transmission, the most important also the most characteristic is the role played good waterproof and dustproof effect. Waterproof connectors, waterproof with waterproof cable connectors and very broad, such as: LED lighting, furniture, appliances, city lighting engineering, shipbuilding, hotels, industrial machinery, marine lighthouse, gifts, etc.

waterproof connector Protection class analytic

Waterproof connector waterproof rating of simple and clearly defined standards strictly to IP as the technical parameters of the guidelines, the two figures behind with representatives of both the scope and meaning alone, but not separated, we are used to "IPXX "to do a general introduction, here, I'll give you step by step explanations, the first" X "represents the" dust "- that is, protection against solids force participation, and the second" X "represents the" waterproof "- also is the protection against liquids.

Talk about the first "X":
When IP is 0, the test without protection, it does not make sense.

When the IP-1, to prevent solids larger than 50mm invasion, it is equivalent to hand contact.

When IP is 2, can prevent the intrusion of solid matter more than 12mm, only the size of our fingers.

When IP 3 is to prevent the threat of intrusion of 2.5mm greater than the solids, e.g., a number of small tools, or a wire.

4 when the IP is possible to prevent the intrusion threats than 1mm solids, e.g. a stripped wire thickness.

When IP is 5:00, you can prevent dust entering harm.

When is 6 IP, is completely prevent dust entering, so the first "X" to do it six, and technology is the most mature.The second terms are "X":
When IP is 0, and as before, the test is not protected.

When the IP-1, to prevent the threat of a vertical drop of water.

When IP is 2, can be prevented to the vertical direction 15 degrees oblique to the shell caused by water damage.

When IP is 3:00, you can prevent the vertical inclination of 60 degrees to the direction of spray damage to the shell.

When IP is 4:00, this time, no matter from which direction the water splash, will not invade the case.

When IP is 5:00, to impose low-pressure water in any direction, the connector will not be hurt.

When IP 6, you can impose all sides of the high-pressure water to it, will not invade the inside, suitable for the working environment within the ship, this time, you can simply asked to fetch water fight.

When the IP is 7:00 into the water, a short immersion, there is no problem.

When IP is 8:00, you can work long hours under high water pressure without water. At the moment, it is waterproof connector highest level of protection.

M12 X circular connectors of the Sensor Actor Line from CONEC are used to connect a distributor box and a sensor.

The M12 style connector comes with a screw lock, used for low voltage and has between 2 and 8 contacts. Conec M12 connectors are IP67 rated and well suited for wet, moisture-laden environments.

These M12 connectors may also be coded. The common used keyed types are:

A-Coded; used with Sensor Actuators

B-Coded; used with field buses

D-Coded; used with Industrial Ethernet X-Coded; used with10 Gbps Ethernet

These connectors can be used to implement a flexible input-output (I/O) or field-bus connection on the circuit board. M12 connectors with D-coding comply with Industrial Ethernet standards (IEC 61067-2-101, Amendment 1). M12 connectors are now recommended for nearly all field-bus specifications, and meet the IP67 protection standards rating (IEC 61076-2-101). They are not intended for use under continuous pressure. In consideration of the broad range of ‘rained on’ definitions, the industry appears to have agreed to a ‘test of immersion for 30 minutes, at a depth of 1 metre, or the equivalent air test at 1.45 psi. That is the Qualification Test. (Protected against the effects of temporary immersion between 15cm and 1metre. Duration of test 30minutes). They are also traditionally used to connect sensors and actuators in automation systems. An expansion (Amendment 1) of the IEC 61076-2-101 standard describes a 4-pole, D-coded variant specified for a higher protective class of Industrial Ethernet applications ~ these requirements correspond to those of a Category-5 modular jack (RJ45) connector, according to the EIA/TIA standard. The D-coding prevents the connector from being confused with the A-coding used for sensor-actuator wiring, or the B-coding used with some field buses.

 

 

Moulded to cable

 

Over-moulded metric type connectors improve durability and streamline the size, as well as the appearance, of a cable connection. Over-moulding can also reduce the cost of lifetime ownership of cable assemblies, making it an important consideration for harsh environment applications. The extra strain relief around the wire terminations offers increased durability because the strain relief bonds to the cable jacket. These connectors, available with 3, 4, 5, 6, 8 and 12 contacts provide innovative connection technology fulfilling the requirements of protection class IP 67. The standard programme has moulded versions with anti-vibration locking and they come in various cable lengths and quality. Components with 2 or 3 LEDs are available to indicate operating voltage and/or the switching status.

 

When it gets really tough: Shielded connectors from CONEC protect and bypass weak signals. A uniform cable shielding ensures seamless signal transmission. Connection cables with a combination of connectors and/or adapters can be used for nearly any cabling application, plus they can be used on many types of machinery using capacitive, inductive or optical sensors.

Why is waterproof connector

We can see a lot of connectors in various fields in our daily life. Let’s take PC as an example, there are many components such as RJ45 connector, VGA connector, DVI connector and power connector.

In industry application, plenty of products require the high strength connector or cable that are made of metal to ensure their use reliability and safety. So , the waterproof industrial connector which can be used in harsh environment are developed.

There are various waterproof connectors for the different application; you also can choose your right type

 

Some special features are developed according to application, for example outdoors LED system requires -25 °C~+80 °C cable and connector. Circular connector M12 series can be used as an accessory on this system because of the waterproof characteristic.  The thread nut with immunity to vibration, Signal's product equivalent to Binder, Phoenix, and it is compatible with almost all types of connectors.

 

Nowadays, the trend of using M12 connector and cable to replace the normal connector is more and more.
