02    M12 initially released in 3-and 4-pin versions, with an IP67 rating. The M8 hit the market four years later, and soon both formats were standardized under IEC 61076-2-101, making them the standard for ICS.Since the introduction of the 3- and 4-pin versions of the M12, many more variations and options have become available. The connectors are offered in both straight and right angle configurations and can now be found in 3-, 4-, 5-, 6-, 8- and 12-pin versions and so on. In addition to IP67, M12 connectors are offered with IP65, IP68 and IP69K ratings. This allows the M12 to be used in the most demanding applications, even where high-pressure washdown processes are required. IP69K applications often require resistance to corrosion, which can be achieved by using stainless-steel coupling nuts.


03  A polyvinyl chloride (PVC) jacketed cable is the most popular cable used with M12 and M8 connectors. A variety of colors are available (for example, yellow, black, gray and orange) and PVC will stand up well in a typical industrial environment.A polyurethane (PUR) jacket is a good choice if constant flexing or abrasion are environmental concerns; PUR-jacketed cables can be found in a variety of colors and some versions are halogen-free.  Shielded cables are available and are frequently used for fieldbus cables (including Ethernet, PROFINET, PROFIBUS, and DeviceNet), but are also used for sensor and actuator cables in high-noise environments. Other cable options include high temperature, industry certifications and armoring. For the oil and gas industry, ensuring that cables can withstand high temperatures is critical, while the mining and shipping sectors are concerned with industry certifications.



M12  circular, 3-pin, screw-type, “waterproof” connector. This overmolded connector was rated to IP67, meaning it was dust tight and remained watertight even if temporarily submerged. Used to connect industrial sensors, this precursor to the M12 found its first industrial automation application at an automotive plant, a market that remains key for the M12 connector to this day.


The M12 connector is also available in a variety of keying/coding options to further minimize wiring errors as follows:

A-code – with 2A, 5A, 10A, 3, 4, 5, 8 pins available. Primarily used with sensors and actuators
B-code – with 5A, 5pins only. for PROFIBUS fieldbus connections
C-code---(dual keyway) – Primarily used with AC sensors and actuators
D-code – with 5A, 3, 4, 5pins available. for 100Mb EtherNet/IP 4-pin
X-code – 0.5A, 8pins only. for Gigabit Ethernet 8-pin


05   M8 and M12 have become favorites for anyone in need of a rugged, sealed connector. In addition to automotive production, other industries that call for specific cables to best meet reliability demands include food and beverage processing environments, machine building, rubber and plastics, textile and printing presses. They’re also seen connected to spray valves on farm implements or coolant valves in HVAC systems. The wide variety of cable types, connector orientations and keying options allows M8 and M12 connectors to address a range of situations and applications.

Product Applications

M8/M12 connectors are used in a variety of applications requiring a rugged and robust fully shielded metal shell able to withstand shock and high vibration. Many industry applications include medical devices, ruggedized data loggers & sensors, electronic gauges & metering, as well as avionics and marine electronics.
