8 Pin X Coded M12 Cable And M12 X Coded Ethernet Pinout

X coded M12 cable is 8 pin X coding M12 connector molded with cable, the cable material could be PUR/PVC , the lead cable length could be customized . The X coded M12 cable is mostly used for industrial ethernet , so it’s also called M12 X coded ethernet cable . The M12 X coded cable could be both end with connector or one end with M12 X coded connector .

Before X coded M12 connector, engineers choose A coded 4 pole , 8 pole or D coded 4 pole M12 connector for industrial ethernet connection, while the A code 4 8 pole also used for sensor connection and data transmission, while also adopt A coded 4 pole and 8 pole for industrial ethernet,there will be the risk of incorrect matching, it is not easy to simply solve the system problem, and it will lead to system damage and production accidents.the M12 D coded 4 pin have transmission speed at 100 Mbit which couldn’t meet the requirements of modern industrial automation for massive data transmission.

Then engineers developed X coding with 8 pin for industrial ethernet, could transmit data at 10 Gbitm,while greatly improving the data transmission speed, production problems caused by incorrect matching are avoided. Therefore, the application of 8 pole X coded M12 connector in industrial automation and industrial Ethernet is becoming more and more popular.

8 pin X coded M12 cable different types

Sorted by connector types, the M12 X coded cable could be one end male/female M12 X coded connector, the other end open, or male/female M12 X coded connector, or RJ45 plug and receptacle.

In different application environments, customers will choose different X coded M12 cables, and may also choose several different types to meet the connection needs of industrial automation and Ethernet, these different types M12 X coded ethernet cable have same transmission speed.

① Overmolded Straight X coded M12 cable

As above picture, we can see the M12 plug of the X coded M12 cable is 8pin straight type , the other end is RJ45 connector , connectors at both side are molded with the cable , the M12 plug is male most times. And the customer could customize the cable length.

② Overmolded Angled X coded M12 cable

Angled X coded M12 cable to RJ45 , one end is male M12 X code plug , the other is male RJ45 connector , why the M12 plug need to be angled ? In some applications , the space is limited , right angled X coded M12 cable can be used for limited space.

③ X coded M12 cable – one side M12 male plug , the other end open

For some applications customer may one end with male/female, straight/angled X coded M12 connector ( in the above picture it’s male angled connector ), the other end free, so the customers could make field installation after they reach the goods.

④ Both end X coded M12 cable

Both end X coded M12 cable, each end may be male and female, also could be straight type and right angled type, although it’s both end with M12 X coded connector, but it’s also for industrial ethernet application , although it’s without RJ45 interface , but it’s just an interface , with M12 X coded interface would also realize the industrial ethernet application. In above picture, it’s both end male M12 X coded cable.

⑤ Panel mount female X coded M12 cable socket

We can see from above picture, the M12 X coded connector is female type, it’s back panel mount X coded M12 socket installed with a shielding tail, it’s mainly used for inside connection, as the connection of the M12 X coded socket and the cable is non-waterproof, if the working environment is dry, then it can be also used outside the equipment.

⑥ Both end female X coded M12 cable 8 pin

This is M12 X coded cable with both end female back panel mount M12 X coded socket.

Cable types of 8 pin X coded M12 cable

The X coded M12 cable consists of two important parts, one is the M12 X coded connector, and the other is the cable. In the above content we mainly talked about the M12 X coded connector, here we focus on the different types of cables.

When it comes to the cable of the X coded M12 cable, we are mainly talking about two aspects: one is the requirements of the Ethernet cable as a data transmission function, on the other hand, the performance of different material jackets in different application environments.

1. X coded M12 cable transmission performance

In the data transmission application of industrial Ethernet, transmission speed and shielding level are the two most important parameters. The transmission speed determines the data transmission capability of the cable, and the shielding level determines the ability to transmit data accurately.

① Data transmission speed of different X coded M12 ethernet cables

As we know the X coded M12 cables mainly use ethernet cables, but there’re many different ethernet cables, from above picture we can see, there are CAT2 , CAT4 , CAT5 , CAT5e , CAT6 , CAT6a , CAT7 (CAT7a CAT8 not listed in the chart), the transmission performance is sequentially better .

The X coded M12 cable could support 10Gbps speed, and sometimes the application only need 1 Gbps , so normally CAT5e CAT6 CAT6a ethernet cables would be available.

• CAT5e ethernet cable is an upgraded version of Cat5 cable. Compared with CAT6, CAT6a is cheaper and can support up to 1 Gigabit transmission speed. It consists of 24-gauge twisted pair wires and supports a frequency of 100MHz.
• CAT6 ethernet cable supports the transmission speed of 10 Gigabit, and the transmission distance can reach 100M, usually using 23AWG conductor, CAT6 ethernet cable is widely used in the current high-speed Ethernet, under the frequency bandwidth of 250MHz, CAT6 cable provides faster transmission speed, much lower signal loss, reduce interference with other cables, Cat6 cables cost about 30% more than CAT5e cables.
• CAT6a is an upgraded version of CAT6 cable. Although it uses the same 23AGW conductor as CAT6, the wire is wounded more tightly, which makes it larger in diameter and uses more conductor material and jacket material. Compared to CAT5e and CAT6 cables, CAT6a cables offer less interference, less signal loss, and 500 MHz frequency bandwidth. In enterprise-class high-speed Ethernet, CAT6a is widely used.

CAZN X coded M12 cables 8 pole adopt CAT5e , CAT6 , and CAT6a for industrial ethernet application .

② Shielding types of X coded M12 cable

From above picture, we can there are different shielding types for the ethernet cables :

First part before the “/” , letter F means Foil shield , it’s foil layer wrapped twisted pair conductors. Letter S means the Braided shield , this is a braid layer with metallic wire which have better shielding.

Second part after the “/” , TP means twisted pair , this is the primary shielding method，two insulated copper wires are twisted together at a certain density. The radio waves radiated from each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing signal interference. Letter F in this part, means there is Foil layer for shielding which wraps each twisted pair.

We can see the S/FTP SF/FTP F/FTP are amount the best EMI performance. CAZN X coded M12 cables adopt the SF/FTP shieding types ethernet cables.

2. Cable jacket and working environment of X coded M12 cables

There’re different environments in automation and industrial ethernet appliction, such as high and low temperature, corrosion, moisture, friction, bending, oil, etc. In order to adapt to different application environments, X coded M12 cable adopts different jackets to achieve the best performance.

The most popular cable jacket is PVC and PUR , and for industrial robots and towline , will need high flex towline cables.

① 8 pole X coded M12 cable PVC jacket

PVC cable jacket is composed of the following components: polyvinyl chloride resin, stabilizer, plasticizer, filler, lubricant, antioxidant, colorant, etc. PVC cable jacket has good voltage resistance and insulation performance, but the disadvantage is that the dielectric constant and dielectric loss are large. Therefore, it is generally mainly used as an insulating layer for low-voltage (≤1KV) and medium-high voltage (6~10KV) cables. PVC jacket has certain flame retardant, oil resistance, chemical corrosion resistance, and water resistance. By changing the formula and adding special performance additives or modifiers, heat-resistant (105°C), cold-resistant, oil-resistant and flame-retardant can be manufactured respectively type, high flex and non-toxic PVC cable materials to meet the needs of special cable products.PVC is the most popular cable jacket material and very cost-effective.

② 8 core X coded M12 cable PUR jacket

PUR cable jacket is made of polyurethane, shorted as TPU, have excellent oil resistance, good toughness, wear resistance, cold resistance (low temperature resistance), water resistance, aging resistance, acid and alkali resistance, weather resistance, long service life, UV resistance, especially suitable for industrial applications with extremely harsh oil pollution and low temperature environments .

So if used for harsh environment , we’d better choose PUR X coded M12 cable.

③Towline X coded M12 cable

Towline cable is also called moving cable , robot cable , high flex towline cable , in industrial automation applications, such as installed in towlines or installed on robots, cables will often frict and bend. Ordinary cables have relatively thicker conductor, not flex enough, and frequent bending may cause the cable to break or break. The towline cable must have very good friction resistance, oil resistance, bending resistance, high and low temperature resistance, etc.

Here is the difference between towline cable and ordinary cable:

• The color and appearance of the drag chain cable are no different from ordinary cables. Some people even think that ordinary cables are more flex. The high flex mentioned here does not mean the degree of softness, but the bending cycles. The towline cable adopts special material cable jacket.
• Thickness of cable jacket: The towline cable jacket is obviously slightly thicker than the ordinary jacket wire, which better guarantees the basic physical properties of the cable.
• Cable roundness: The filler of towline cable is significantly more than that of ordinary sheathed wire, which makes the cable more rounded, it is also part of the reason why the cable is slightly stiffer.
• The drag chain cable adopts oxygen-free bare copper wire multi-strand finely twisted bundle, referring to VDE 0295/CLASS 6 conductor standard.
