Reliable networking device with safety
protection
Korenix has introduced the JetNet range of Ethernet connectors with enhanced isolation safety protection and suitability to harsh environments.
To ensure their networking devices operate in harsh environments successfully, Korenix JetNet 5010G/3010G/4508 industrial Ethernet switches and JetCon 1301 industrial media converters have passed the following life vibration and life shock tests: IEC 61000-2-6 life vibration tests l 5~100Hz/Amplitude 1mm, 0.7g /90Min, X.Y.Z., 6 axis l 3~50Hz/Amplitude 3.5mm,1g/90Min, X.Y.Z., 6 axis IEC 61000-2-27 life shock test l 50G , 11ms duration, X,Y,Z, 3 shock/axes ( Total 18 shocks) It is also important to build a Ethernet connection with enhanced isolation safety protection

JetNet 5010G/3010G/4508/2005 and JetCon 1301 series provide High 1200 VAC Port to Port Isolation Protection (e.g Ethernet port to Ethernet port, Ethernet port to power input, Ethernet port to chassis, Power Input to chassis) to protect the operator from electrical shock.
HiPOT (High Potential) is a term given to a class of electrical safety testing instruments used to verify electrical insulation in finished appliances, cables or other wired assemblies.
The Korenix networking devices have designed in the port isolation grounding, shield insulation and kept sustainable isolation gap between earth ground and digital ground to withstand the HiPOT 1200 VAC level test.
It provides an enhancement safety to operators in installation, regular maintenance or trouble shooting service.
Under normal conditions, any electrical device will produce a minimal amount of leakage current due to the voltages and internal capacitance present within the product.
Due to design defects or other factors, the insulation in a product can break down, resulting in excessive leakage current flow.
This failure condition can cause shock or damage to anyone that comes into contact with the faulty product.
A HiPOT test (also called a Dielectric Withstand test) verifies that the insulation of a product or component is sufficient enough to protect the operator from electrical shock.
In a HiPOT test, high voltage is applied between a product's current-carrying conductors and its metallic chassis.
The resulting current that flows through the insulation, known as leakage current, is monitored by the tester.
