M12 Connectors Cable Rugged Compact Sealed Connectors Used for Signal Data and Power Connectivity in Industrial Control Applications.
M12 Connectors are the global standard for robust, circular interconnects in industrial automation and harsh environments. Renowned for their compact size, threaded coupling mechanism, and excellent IP (Ingress Protection) ratings, they provide reliable data and power transmission for sensors, actuators, fieldbus systems, and Industrial Ethernet applications. Our comprehensive portfolio covers all major coding types, pin counts, and termination styles to meet the precise demands of your system.
Key Features & Benefits:
Rugged & Reliable: The 12mm threaded locking mechanism ensures a vibration-proof connection, while standard IP67/IP68/IP69K ratings guarantee protection against dust, water, and high-pressure washdowns.
Multiple Codings (Keying): Prevents mis-mating and ensures signal integrity:
A-Coded: The most common type, used for sensors, actuators, DC power, and generic I/O. (Typically 3-5 pins)
B-Coded: Used for Profibus fieldbus networks. (5 pins)
D-Coded: Primarily used for 100 Mbit Industrial Ethernet (e.g., PROFINET) and some fieldbus systems. (4 pins)
X-Coded: Designed for 10 Gbit/s high-speed Industrial Ethernet and Gigabit Ethernet, supporting higher frequencies. (8 pins)
S-Coded & T-Coded: For AC power and specific power supply applications.
Various Configurations:
Cable Connectors: (Plug & Receptacle) Straight or right-angle designs.
Panel Mount Receptacles: For mounting on equipment enclosures.
PCB Mount Receptacles: For direct board connection.
High-Performance Materials: Typically constructed with PBT or PA housings and nickel-plated brass shells for superior chemical and mechanical resistance.
Applications:
M12 connectors are indispensable in virtually all industrial sectors:
Industrial Automation & Robotics: (PLC I/O, motor drives, vision systems)
Industrial Ethernet & Fieldbus: (PROFINET, EtherNet/IP, EtherCAT, Profibus)
Sensor & Actuator Networks: (Proximity sensors, photoelectric sensors, valves)
Factory Process Control & Instrumentation
Transportation & Heavy Machinery
Renewable Energy: (Solar and wind farm control systems)
