The M16 series delivers superior electrical performance with higher current and voltage tolerance than small-size M-series connectors. Rated current reaches 10A for 2/3/4Pin models, 8A for 5/6/8Pin models and 5A for 12Pin models. The rated working voltage is 300V AC/DC for low-pin configurations and 250V AC/DC for high-pin configurations. The product features a dielectric withstand voltage of 2500V AC for one minute without breakdown or flashover, providing powerful overvoltage surge protection for industrial circuits. The insulation resistance is greater than 2000MΩ under normal temperature and humidity, effectively preventing current leakage, short circuit and insulation aging failure in high-temperature and humid environments.
The contact resistance is strictly controlled below 3mΩ, ensuring ultra-low-loss signal and power transmission without data attenuation, delay or distortion. Conductive pins are made of high-purity oxygen-free copper with gold-plated surface treatment, greatly enhancing conductivity, oxidation resistance and corrosion resistance. The mechanical and electrical plugging lifespan exceeds 2500 cycles, maintaining stable and consistent electrical performance during long-term continuous operation and repeated plugging.
1.3 Mechanical Performance Parameters
Equipped with reinforced M16 standard thread structure, the connector features stable locking torque ranging from 0.8N·m to 1.2N·m, providing excellent anti-loosening capability against mechanical vibration, equipment operation and external impact. The plugging force is uniform and moderate, enabling convenient manual assembly and daily maintenance without pin deformation or shell damage. The PCB mount models adopt reinforced pin fixing structure, ensuring firm soldering and anti-fall performance after board installation. The whole series can withstand continuous high-frequency vibration from 10Hz to 2000Hz, fully adapting to long-term operation of vibrating mechanical equipment and mobile industrial devices.
1.4 Environmental Performance Parameters
The operating temperature range of the M16 connector is -40℃ to +85℃, and the storage temperature ranges from -50℃ to +110℃. It maintains stable structural integrity and electrical performance under extreme low-temperature freezing, high-temperature baking and frequent cold-hot alternating cycles, with no cracking, deformation or performance degradation. The product can continuously work in 95%RH non-condensing high humidity conditions, possessing excellent moisture-proof, mildew-proof and anti-corrosion characteristics.
The plastic housing version achieves IP44 dustproof and splash-proof protection grade, perfectly suitable for indoor closed environments, commercial intelligent equipment and general industrial control rooms. The metal housing version reaches industrial IP67 high-grade dustproof and waterproof performance, completely isolating dust intrusion and resisting short-term water immersion, rain erosion, fog and harsh weather conditions, making it ideal for outdoor engineering, open-air equipment and humid dusty workshops.
1.5 Soldering Process Parameters
The recommended soldering temperature is 340℃ to 400℃, with single-point soldering time controlled within 2 to 5 seconds to avoid high-temperature damage to the insulating body. The product supports lead-free environmental solder and fully complies with RoHS environmental protection standards. Optimized terminal spacing and high-temperature resistant structure effectively prevent tin bridging and short circuit during manual soldering, ensuring high assembly yield and stable wiring quality for mass production and on-site construction.
