M8 to M12 Cables, Adapter : How To Connect M8 To M12 ?

How to connect two devices with different interfaces of M8 and M12 together? Then you need to use M8 to M12 adapter (which is also called M12 to M8 adapter) or M8 to M12 cable (which is also called M12 to M8 cable).

In some industrial automation applications, engineers may face the problem of connecting devices with two different interfaces. The most common situations include connecting a device with a M12 interface to a device with M8 interface, and connecting a device with M12 interface to a device with a RJ45 interface, connecting a M12 device to a device with DB15 interface, connect an M12 device to a device with USB interface, etc. Here we focus on how to make M8 to M12 .

What Is M12 To M8 Adapter ?

M12 to M8 adapter is device that have both M8 and M12 interface, it can connect M8 cable and M12 cable, and make the connection waterproof, so the Power or signal transmission can be realized. There is a precondition for this，the M8 device and M12 device should alreay have cables on it, and one have M8 lead cable, the other have M12 lead cable, then we can use M12 to M8 adapter.

The above pictures shows 2 different types M8 to M12 adatper , the left one is from Phoenix , have one A coded 4 pin M12 male interface and one female M8 A coded 4 pin interface, so it can connect a female M12 cable and a male M8 cable, and both the cable should be A coded 4 pin.

The right is Y type M8 to M12 adapter from CAZN, it has 2 female A coded 4 pin M8 interface, and one 4 pin A coded male M12 interface, so it can connector two male M8 A coded 4 pin cable and one female M12 A coded 4 pin cable.

So we can know that, not all M8 cables and M12 cables could be connected together, the M12 cable should have same coding type and pin quantity with the M12 interface of M8 to M12 adatper , and if the M12 interface of M8 to M12 adapter is male, then the M12 cable should be female. And it’s the same, the M8 cable should have same coding type and pin quantity with M8 interface of M8 to M12 adatper , and if the M8 interface of M8 to M12 adapter is female, then the M8 cable should be male.

Why the M12 interface of the M8 to M12 adapter is male , and M8 interface of the M8 to M12 adapter is female ?

As we know, the sensor should feedback datas to control system, the the situation will need M8 to M12 is that the sensor have M8 interface, and normally the connector on the sensor is male, then the end of the M8 lead cable should be male(normally the both end M8 lead cable is male to female), so it can connect to the M8 side of the M8 to M12 adapter.

The M12 interface at control system side normally is female（prevent electric shock）, so the M8 to M12 adapter could connect to the control system(or to the M12 lead cable that connect to the control system), the M8 side of the M8 to M12 adapter connect to the sensor.

Note : In above picture, the 21 device is M8 to M12 adapter. The M12 to M8 adapter is better choice for the systems with prewired sensor and actuator.

Can the adapter be produced as M8 male to M12 female adatper ?

Sometimes there’re different requirements for the M8 to M12 adaters, M8 male to M12 female adapter is also available. Normally it’s A coded 3 pin M8 male to M12 female A coded 3 pin, or A coded 4 pin M8 male to M12 female A coded 4 pin.

People may ask, is the Y type M12 to M8 adatper can also be M8 male to M12 female adapter ? The answer is yes, products design always come from the actual requirements.

M8 To M12 Cable

Sometimes the sensor and actuator come with M8 interface and don’t have cables, but need connect to I/O modules or direct connector control system that have M12 interface, then it’s better choice to use M8 to M12 cables.

M8 to M12 cable is normally both end cables, one side is M12 connector ,the other side is M8 connector , the most popular ones is female M8 to M12 male cable , 3 pin and 4 pin had been used mostly.

Each end of the M8 to M12 cable could be straight or right angle, the product could be customized with detail requirement.

Main features of the M8 to M12 cable :

• Code type : A coded / D coded
• Pin quantity : 3 pin / 4 pin
• Connector side A : M12
• Connector side B : M8
• Protection : IP67
• Standard : EN IEC 61076-2-101
• Cable jacket material : PVC / PUR
• Cable length : 1M / 2M / 3M / 5M / customized
• Towline cable / moving cable / robot cable is available
• Termination : moulded with cable
• Working temperature : -25 °C / 85 °C
• Halogen free : yes

The M8 to M12 cable could be made M12 side have more pins than M8 side , then some pins of the M12 side will be blank , such 8 pin A coded M12 to M8 4 pin cable A coded.

Application of M12 to M8 adapter and M8 to M12 cable

The M12 to M8 adapter and M8 to M12 cable are widely used in the connection of sensors, actuators and control systems in automation applications, and can provide safe and reliable connections for automatic control systems. They can reach IP67 protection performance, and have certain resistance to liquid and gas corrosion, vibration resistance, etc., and are ideal for connecting M8 and M12 in industrial environments.

Customized M8 to M12 adapter and cable

In specific automation applications, the existing products may not meet the needs of customers. At this time, some customized M12 to M8 adapter and M8 to M12 cable may be required.

We have a team of experienced engineers who are responsible for modeling according to your needs, have mold processing, injection molding production, wire extrusion production line, hardware processing workshop, complete design, manufacturing, testing equipment, to ensure that your needs can be met.
