The M-series circular connectors offer a wide range of protection levels due to their wide range of application scenarios. These levels of protection usually follow the standards set by the International Electrotechnical Commission (IEC), such as IP65, IP67 and IP68. The following are several common levels of protection and their characteristics:IP65: This rating indicates complete protection against dust entry and resistance to low-pressure water jets from all directions. Suitable for most indoor or light outdoor use.IP67: In addition to all the characteristics of IP65, it can be immersed in water to a depth of 1 meter in a short time (usually 30 minutes) without damage. Suitable for situations where splashing or occasional flooding is possible.IP68: This is one of the highest levels of protection, meaning that the equipment is not only completely insulated from dust, but can also continue to work at a certain depth of water for a long time. Connectors of this class are ideal for applications in extreme conditions, such as underwater operations or other situations requiring a high degree of tightness.Choosing the right level of protection depends on the specific needs of the target application and the expected operating environment. For example, connectors used in agricultural machinery may require increased water and dust resistance to cope with adverse weather conditions; A data transmission network deployed in a factory may only require a lower level of protection.Note:When determining the level of protection required, carefully evaluate the potential risk factors in the actual working environment.Even for products with a nominal high level of protection, attention should be paid to the correct sealing treatment during the actual installation process to ensure the desired effect.

Circular connector wiring methods mainly include the following: Crimp wiring: this method uses a crimping tool to crimp the metal part of the connector to the wire or terminal to form a strong electrical connection. Crimp wiring is suitable for high-frequency and high-current applications with high connection strength, and is commonly used in automation equipment and power connections. Solder wire wiring: connecting the pins of the connector to the circuit board or cable by soldering, suitable for long-term stable connection needs, commonly used in fixed devices such as home appliances and industrial equipment. Nut lock wiring: the use of nuts to fix the connector pins, suitable for frequent plugging and unplugging occasions, convenient operation. Threaded connections: Connections and disconnections are made by tightening and loosening the threads, suitable for environments that require resistance to vibration and shock, commonly found in aerospace, military and heavy industrial equipment. Bayonet connections: A bayonet or plug with a specific design that requires forceful pressing or turning to lock it in place after insertion, suitable for audio/video equipment, computer peripherals and communications equipment. Plug-in and plug-out connections: Connections are made by directly inserting and removing the connector, usually by means of a snap-lock or latch mechanism, and are suitable for applications that require frequent connections and disconnections, such as test equipment and laboratory instruments.

The M12 name comes from the metric thread on the coupling nut and mating socket of most connectors. They are basically 12 mm diameter fasteners with an M12 thread.

For data applications, there are five main types of M12 connectors with key positions A, B, C, D or X. These connectors are available with 2, 3, 4, 5, 6, 8, 12, or 17 pins. Depending on the number of signals, type of signals, type of interface involved in the connection, and the connector code.

M8 connectors, with an 8-mm circular coupler, are specifically used in industrial automated systems, typically linking sensors, actuators, and switches. M8 connectors can be used for similar applications as M12, but have a smaller footprint incorporating an 8mm threaded head.
