Our M12 series is designed with the core philosophy of "all-scenario adaptability and robust durability." The product line comprehensively covers three mainstream keying codes: A (sensor/signal), B (fieldbus), and D (industrial Ethernet), and offers various combinations including 2 to 17 pins, shielded and unshielded options, wire-end and PCB-end connections, and front and rear locking mechanisms. We utilize high-specification brass/phosphor bronze gold-plated contacts and PA66 insulating inserts to ensure excellent conductivity and weather resistance. Its robust brass housing, coupled with a precision structure, achieves a reliable IP67 protection rating and passes a 48-hour salt spray test, effectively addressing the challenges of moisture, dust, and corrosion in industrial environments, solving the common pain points of performance degradation and premature failure caused by environmental stress on connectors.
This series strictly adheres to the IEC61076-2-101 standard, and its performance parameters are rigorously verified. All products can operate stably in extreme temperature ranges from -40℃ to +105℃, adapting to a wide range of applications from cold storage warehouses to high-temperature workshops. The mechanical life exceeds 100 mating cycles, meeting the needs of frequent equipment maintenance and debugging. Its stable electrical performance and rigorous physical structure ensure that connections remain secure and signals remain uninterrupted even under continuous vibration and temperature fluctuations.
