Rated current: 5A (2/3/4 core), 3A (5/6 core); Rated voltage: 60V AC/DC; Withstand voltage: 1800V AC (50Hz, 1min), ensuring strong insulation and breakdown resistance under instantaneous voltage fluctuation. The insulation resistance reaches ≥1200MΩ under normal temperature and humidity, effectively avoiding leakage current, short circuit and circuit failure caused by damp and aging. The contact resistance is controlled below 8mΩ, realizing low-loss and high-stability signal and power transmission without signal attenuation, delay or distortion.
The conductive pins are made of high-purity copper alloy with gold-plated surface treatment, featuring excellent conductivity, oxidation resistance and corrosion resistance. The electrical plugging life exceeds 1500 cycles, maintaining stable electrical performance after long-term repeated plugging and continuous power-on operation, fully meeting the long-term working requirements of industrial equipment.
1.3 Mechanical Performance
The M10 connector adopts reinforced thread locking design with locking torque ranging from 0.5N·m to 0.9N·m, realizing firm locking and anti-loosening effect. The plugging force is uniform and moderate, convenient for manual assembly and daily maintenance without damaging pins or insulating components. The product can withstand continuous vibration of 10Hz–2000Hz and instantaneous mechanical impact, adapting to long-term vibration working environments of automated production equipment and mechanical devices. The root of the PCB welding terminal is structurally reinforced to effectively resist welding stress and external pulling force, preventing virtual welding, terminal falling off and poor contact failure.
1.4 Environmental Adaptability Parameters
Working temperature range: -40℃ to +85℃; storage temperature: -50℃ to +90℃. The product can work stably in extreme low temperature, high temperature and alternating cold and hot environments without deformation, aging or performance degradation. It can withstand long-term high humidity environment of 95%RH non-condensing, with stable insulation performance and anti-mildew and anti-corrosion capabilities. The plastic housing version reaches IP44 protection grade for dust and splash water prevention, suitable for indoor and protected environments. The metal housing upgraded version reaches IP67 dustproof and waterproof grade, capable of preventing dust infiltration and resisting short-term water immersion, fully adapting to outdoor exposure, workshop dust, splashing water and other harsh industrial scenarios.
1.5 Welding & Assembly Parameters
For wire soldering type connectors, the optimal soldering temperature is 320℃–390℃ with single-point soldering time controlled within 2–3 seconds to avoid high-temperature damage to the insulator. Compatible with lead-free environmentally friendly solder, it meets global environmental protection standards. The recommended wire stripping length is 4–6mm to ensure full soldering and firm connection. For straight and right-angle PCB mount connectors, both manual soldering and wave soldering processes are applicable with high welding yield and stable batch consistency.
Product Features & Core Advantages
