introduceIndustrial plug is an industrial plug, which is mainly waterproof and can even be used directly in water. Generally, industrial plugs have 3, 4 and 5 cores, and the supported currents are 16a, 32a, 63a, 125a, 250a, 420a, etc. When purchasing industrial plugs, they should be used together with industrial sockets and cee connectors, and the protection level is ip44. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt commutation device quickly and braking device effectively. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits.How to choose the right industrial plug1. How do I choose the right connector plug to use? The first thing we need to consider is where the plug needs to be connected and where the connector plug needs to be used. This problem needs very careful consideration. Whether it needs to be used indoors or outdoors, the type of industrial plug will determine which terminal technology to use as a reference.2. Electrical requirements When selecting electrical connectors, the electrical requirements of products should be considered. What kind of voltage and current requirements of the product, and whether the connector can be well used in such electrical properties, these electrical requirements need us to consider. In addition, we also need to consider other electrical conditions: resistance, allowable resistance variation, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, VSWR (voltage standing wave ratio), plugging loss and EMI shielding efficiency.
