Having the right components in place is essential for getting a job done, and with many connector types available it’s important to know the distinctions between the various options.
When it comes to M12 vs. M8 connectors, there are certainly many overlapping attributes, but there are also some key differences. Let’s take a look at how M8 and M12 connectors differ, how they are utilized, best practices for operation, and everything that iCONN Systems can provide for your operations.
What Is the Difference Between M8 and M12 Connectors?
M12 and M8 connectors facilitate the transfer of data in a system, so ensuring use of the correct connector is key for the proper transfer of information.
M12 connectors utilize a 12 mm threaded, circular head that delivers a robust, but flexible, connection to a variety of other types of equipment. Developed for application in environments that lead to corrosion, the design of M12 connectors inhibits such issues. Settings that necessitate significant data transfer rates are also prime uses of M12 connectors. These connectors often feature 2, 3, 4, 5, 6, 8, 12, or 17 pins to fit accompanying holes.
M8 connectors, meanwhile, feature an 8 mm circular head and are often employed in many industrial settings. Their use overlaps with M12 connectors in many ways, but because of their smaller footprint, via the 8 mm housing, they may be more preferable in some cases. These connectors often feature 3, 4, 5, 6, or 8 pins to fit accompanying holes. Male and female and straight and angled options are available.
Applications: What Are M8 Connectors Used For?
M8 connectors are primarily utilized within industrial automated systems, where they link actuators, sensors, switches, and other components. Settings that necessitate a lightweight connector or those with minimal space are ideal candidates for M8 connectors, which is one of the reasons they are often employed in projects within the automotive field.
Other notable industries that use M8 connectors include HVAC, textile and printing, food and beverage processing, machine building, rubber and plastics, and many more.
Applications: What Are M12 Connectors Used For?
As noted above, M12 connectors were designed for utilization in corrosive environments, and also help in applications that require significant data transfer. Often used within industrial automation settings, these connectors are put to use in applications relating to actuators, sensors, Profibus, Fieldbus, industrial Ethernet, and more.
Due to their rugged construction, dependability, and small size, M12 connectors are particularly prized within the industry, being high among the most utilized components.
Size and Design: M8 vs. M12 Connectors
As industry veterans are aware, the “M” of these connectors’ names indicates “metric,” with the accompanying number describing the connector head’s diameter size in millimeters.
The M12 connector has become something of a classic within the field, with its popularity leading to the development of varied pin structures to facilitate diverse applications. M8 connectors, meanwhile, are known for their resistance to shock, vibration, and moisture, making them the connectors of choice in harsh environments that would pose significant problems for other types.
M8 and M12 Connector Coding Designations
Coding for M8 and M12 connectors is broken down into the classifications of A, B, C, D, and X. “A Coded” connectors feature a variable number of pins and are usually employed in lower-power settings. Due to its ubiquity and ease of use, A Coding is the default. “B Coded” connectors, meanwhile, are utilized for network cables for Fieldbus applications.
“C Coded” connectors are not as common as their A and B counterparts, but are used with AC sensors and actuators. “D Coded” connectors are utilized within Ethernet and ProfiNet systems, transferring data up to 100 megabytes. Lastly, “X Coded” connectors are a newer development within the space, being able to facilitate the transfer of data in the gigabyte range.
