M series Cable& Connector

PVC – Polyvinylchloride jacketing is the most common and cheapest option for M12 cables. It provides very good protection and rigidity for cable, but does not flex very well under extreme conditions. It works well for stationary connections and Easy Strip applications

PUR – PolyUrethane Rigid Foam – A high performance jacket material made for the robotic industry. There are varying grades of flex capable of this type of jacket defined below

Flex – Greater than 2 million bend cycles, C-Track Rated, enhanced oil and abrasion resistance

High Flex – Greater than 10 million bend cycles with 180 degree torsion rated

Robotic Flex – Same >10 million bend cycle rating, but has the ability to torsion 360 degrees

●It must be noted that this type of material is NOT used for insulating internal electrical conductors as it has poor electrical characteristics, but works rather well as a jacketing material because of its resistance to chemicals, high flex, and stability over a wide temperature range. 

Within the two-digit IP rating, the first digit indicates the level of protection against solid objects like dirt or dust, whereas the second digit represents the level of protection against liquids (including dripping water, sprays, splashes, summersion etc.)

M12 connectors commonly hold IP67, IP68, and IP69K certifications, demonstrating their suitability for demanding applications

IP67: This rating signifies that the connector is completely dust-tight, having complete protection against contact up to 8 hours, and can withstand powerful water jets from any direction, as well as temporary immersion up to 1 meter for 30 minutes. This type of M12 connector is a popular choice for applications involving frequent exposure to dust, washdowns, splashes, or temporary underwater use.

IP68: This indicates that the connector has the same resistance against solids and water jets as the IP67 rating, while also being able to withstand prolonged immersion in water up to 1.5 meters for 30 minutes, making it ideal for environments prone to occasional flooding.

IP69K: Not only are IP69-K rated M12 connectors dust-tight, they can also endure high-pressure, high-temperature water jets commonly used in industrial cleaning processes. This makes them perfect for applications in the food and beverage industry, chemical plants, or anywhere requires frequent rigorous cleaning.

Rugged and Reliable Performance
M12 connectors are ideal for industrial environments in part because they offer superior performance in harsh conditions. M12 connectors offer a minimum of IP67-rated environmental protection against dust and water and also protect against impact, vibration, UV exposure, and temperature cycling. For the most demanding applications, such as those subject to frequent washdowns, they are also available with IP68 and IP69K sealing.
Mating cycle ratings are also an important consideration for machine builders choosing a connector for their application. Connector mating cycles are determined by the properties of the contact and plating materials used, as well as the thickness of the plating. Cheaper connectors, such as tin-plated copper alloy contacts, will not perform as well as those made with corrosion-resistant materials, such as gold-plated beryllium copper contacts, which are typically rated for more than 100 mating cycles.

EMI Shielding
Hard-wired M12 connections also offer some advantages over wireless connections, including the intrinsic security of physical connections and protection from interference, which is especially critical in IIoT-enabled factories filled with electromagnetic interference (EMI), such as radio frequency interference (RFI). Unseen and unheard by people, this electronic noise pollution frequently interferes with high-precision sensors already taxed by the physical noise and vibrations of a busy factory floor.

Compact Size
In addition to high signal integrity, Industry 4.0 applications demand ever more compact components and connectivity solutions, even as power and data transmission needs grow. Increasingly smaller devices and sensors are transmitting more data, which requires more connection points and means that connectors must deliver the same — if not greater — power density in a smaller footprint.
Originally designed to reduce the size of the original 7/8" standard sensor connectors, M12 connectors have an outside diameter of just 12mm. This small footprint makes M12s well suited for applications with little available space, including automation control systems, telemetry modules, compact LED lighting fixtures, and value actuators.
M12 connectors can transmit impressive amounts of data and power in rugged industrial environments and feature several critical features that enhance ruggedness, reduce interference, and enable flexibility. As such, they are sure to remain essential components as Industry 4.0 applications continue to expand and mature.
