Velle Electric is a high-tech enterprise integrating research and development, production and sales of industrial connectors (heavy-duty connectors) include M12 plug. With the goal of leading the brand in quality and technology, we have modern working places such as injection molding, hardware, die casting, electroplating, assembly and mold, in addition to product research and development and product performance testing room, and a number of technical patents.
Since its introduction in 1985, the M12 plug has grown to become the interconnection system of choice in industrial automation. These robust connectors enable reliable connectivity in the harshest environments, revolutionizing connectivity in industrial automation. The M12 plug is a circular connector with a 12 mm locking thread and generally has an IP protection class against liquid and solid intrusion. The M12 plug is ideal for sensors, actuators, and industrial Ethernet and fieldbus devices, primarily in industrial automation and corrosive environments.
Before the development of the M12 plug, engineers either pulled the wire directly, or had to repeatedly replace the connector due to poor service conditions. Originally released as 3 – and 4-pin models, the M12 plug was inferior to its predecessor, the RK30 connector, in terms of the maximum current allowed to flow, but it offered IP67 protection. The 4-pin M12 plug allows a single system to incorporate more advanced sensors and actuators. Today, these robust connectors are available in 3 -, 4 -, 5 -, 8 – and 12-pin configurations, and new locking methods such as bayonet and push-pull are constantly being developed. In addition to factory automation, M12 connectors and M12 cable assemblies can be used in measurement and control, communications, transportation, robotics, agriculture, and alternative energy. The right number of pins depends on the specific application needs – 3 and 4 pin models are used for sensor and power applications; 4 – and 8-pin models for Ethernet and PROFINET; DeviceNet and CANbus generally use 4-pin and 5-pin M12 connectors; 12-pin models are commonly used for a variety of signal applications. In addition to the different pin counts, the M12 plug also utilizes multiple key codes to prevent mismatching. The following are the most common types of encodings and their uses.
A code: Sensor, DC, 1G Ethernet
B code: PROFIBUSl C code: AC
D code: 100M Ethernet
X code: 10G Ethernet
S code: AC (to replace C-code power parts)
T code: The most popular types of M12 plug codes for direct current (soon to replace A-code power parts) are A-code, B-code, D-code, and X-code. A-codes, B-codes, and X-codes are some of the earliest M12 plug developed and longest on the market. In high-speed industrial Ethernet, X-coded connectors are in growing demand and will eventually replace A-coded and D-coded components in Ethernet applications. The latest M12 coding types currently under development are K for AC and L for PROFINET DC.
M12 plug and M12 cable assemblies are also used in measurement and control, communications, transportation, robotics, agriculture, and alternative energy. The right number of pins depends on the specific application needs – 3 and 4 pin models are used for sensor and power applications; 4 – and 8-pin models for Ethernet and PROFINET; DeviceNet and CANbus generally use 4-pin and 5-pin M12 connectors; 12-pin models are commonly used for a variety of signal applications.
The most popular M12 encoding types are A-encoding, B-encoding, D-encoding, and X-encoding. A-codes, B-codes, and X-codes are some of the earliest M12 plug developed and longest on the market. In high-speed industrial Ethernet, X-coded connectors are in growing demand and will eventually replace A-coded and D-coded components in Ethernet applications. The latest M12 coding types currently under development are K for AC and L for PROFINET DC. M12 connector coding, M12 connector pin distribution, M12 plug wiring color coding for the design and manufacture of industrial automation equipment, industrial robots, outdoor video surveillance, sensors and other customers introduced M12 circular waterproof connector key coding, pin distribution, wiring color coding, installation classification. If you want a safe, reliable, sealed, waterproof power and signal connection between actuators, sensors and industrial equipment, robots, automation equipment, you are better off with IP67 round waterproof M12 plug and cable assemblies. How to choose the right m12 connector and cable assembly for your application?
How to identify the m12 loop connector code? How do I connect different colored cores to the correct pins/positions of m12 male or female connectors? How do I select the right m12 plug and cable components to install into my device? In order to help the general audience solve the above problems, and to design and assemble power and signal connection systems for specific industrial applications, I will introduce the following different topics: I.M12 plug codes have the following male and female connectors: A code, B code, C code, D code, X code, S code, T code, L code, P code m12 connector. You can identify the encoding types of these m12 series by the following contact layout diagram: M12 A-coding connector 3pins 4pins 5pins 8pins 12pins 17pins pin layout.
S-code circular M12 plug features the following:
1, High performance: AC connector, up to 16A and 630V AC
2, because of the high protection, S-code AC connectors can be safely used in the field
3, flexible: connectors for field assembly
4, wiring method: welding proven connection technology, suitable for a variety of different conductors
5, use a special S code to prevent incorrect connections
The compact size of the M12 plug makes it suitable for applications with less free space such as automotive, manufacturing, machine building and power transmission.
This low maintenance connector is reliable, easy to install and can be used for both male and female M12 plug. Its compact design and high power transmission make it a cost-effective solution for operations that require reliable, flexible connectors.
No rules can not be circular, no matter what industry, what product, in the production and use of their own standards, M12 plug is no exception. So what are the standards used for M12 plug.
M12 plug product design environment requirements are very demanding, product performance, testing standards have passed the international quality testing standards certification. The M12 connector is also used for field sensor and brake connection.
IEC 60664-1; 1992.11. Insulation match
The international standard and German DIN VDE 0110-1 1997.4
This standard is the basic standard for achieving a safe insulation fit. It contains important parameters that specify the electrical clearance of electrical equipment (such as connectors),
creepage distance. Due to the influence of small environmental conditions and other external factors, the expected lifetime is given, including the influence of voltage test method on insulation fit.
IEC 60512; 1994.5. Measurement and test methods
This international standard corresponds to the European standard DIN EN 60512 and the earlier German standard DIN 41640. It specifies measurement and test standards for electrical components such as connectors. The scope of this standard is extensive and all electrical, mechanical and air tests are described in the new section, in addition to test standards for weldability, tightness, shielding and cable tension.
IEC 60529; 1992.11. Protection level of enclosure (Code :IP)
This international standard is compatible with the European standard DIN EN 60529 and the earlier German standard DIN VDE 0470-1 1992.11. Corresponding. It specifies the symbols, conditions, and classification of protection categories for the enclosures of electrical equipment (e.g., connectors), estimating protection against foreign objects and water. This protection standard is represented by an IP code.
IEC 60068-1; 1995.3. Environmental tests
This international standard corresponds to the European standard DIN EN 60068-1. It contains basic protocols for environmental testing and testing. This test process is used to demonstrate the resistance of the component to the environment during use. Typical tests are: cold – dry heat and wet heat, collision, vibration and temperature change.
DIN VDE 0627; 1986.6. Connectors and plug-in devices
The standard has been modified for a long time and shortened to become an international standard. This standard requires the contact to be tested at a test voltage of 1000V or 1500V and a test current of 125A. From a safety point of view, these contacts are used in industrial equipment, or in the measurement, regulation or control circuits of circuits, it is also effective for connectors and connectors of household appliances and information processing equipment.
