They are available with 3, 4, 5, 8, 12 and 17 pins. <\/strong><\/p>\n<p><strong>The M12 family can be found in many applications such as factory automation, communications, measurement and control, food and beverage, transportation, robotics etc.<\/strong><\/p>\n<p><strong>When it comes to specific applications, users must select the right pin count. <\/strong><\/p>\n<p><strong>For sensors and power applications, 3 and 4 pins are required. <\/strong><\/p>\n<p><strong>Profinet and Ethernet use 4 and 8 pin counts.<\/strong><\/p>\n<p><strong>Fieldbus, CANbus and DeviceNet primarily use 4 and 5 pin counts. <\/strong><\/p>\n<p><strong>Finally, specify 12 pins for signal requirements.<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Several styles of coding exist in M12 connectors. This coding prevents incorrect mating on products. In addition, shielding is available in most coded M12 connectors.
