The standard of waterproof connector sealing is IP waterproof level standard. Let’s check the last two digits of IP ,the first number is 0 to 6;The second number is from 0 to 8 .Therefore ,the highest waterproof level of waterproof connector is IP68 . Different IP waterproof level have different test standards,especially ip68 waterproof grade.The test equipment,test conditions and test time should be recognized by both parties. It’s much tougher than the ip67 .
The ip68 test standard is continuous water immersion under a certain pressure. All the ip68 waterproof connectors( ip68 waterproof junction boxes and ip68 waterproof cable connector) of SHENZHEN GREENWAY ELECTRONIC CO., Ltd have been tested by TUV company and obtained the European TUV 、 CE and SAA certificate.The water depth is 4 meters,and the water is continuously soaked for 72 hours .
The connectors of greenway electronics are made of high water-proof silicone sealing rings,waterproof rubber plugs and anti-regressive cable joints ,so as to prevent the joints from being loose due to thermal expansion and cold shrinkage during the use of the connectors ,but not good waterproof .
During application of waterproof connector,due to the change of the environment,thermal expansion and cold shrinkage will occur,so the test standard will also change with the environment .Therefore,the customer will simulate thermal expansion and cold shrinkage for testing,and in the testing process,it needs to make corresponding adjustments according to the actual using condition . if the connector is used for underwater, the heating test must be conducted after the connector is immersed in water and reach the specified temperature,rather than heating the product first and then immersing in the water.if the connector is used for outdoor ,the sustainable temperature is tested by simulated rain shower .
Greenway connector is high waterproof level ,strict standard ,it is your best choice.
