Electromagnetic Compatibility Metal Armored Cable Connector

Sep. 29, 2018

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment and to produce unacceptable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, the electromagnetic interference generated by the equipment in the normal operation process cannot exceed a certain limit; on the other hand, the appliance has certain electromagnetic interference in the environment. The degree of immunity, ie electromagnetic sensitivity.

In the natural world, various operating electrical equipments are related to each other and interact with each other in three ways: electromagnetic conduction, electromagnetic induction and electromagnetic radiation. Under certain conditions, it will cause interference, influence and harm to the running equipment and personnel.

Internal interference refers to mutual interference between various components inside an electronic device, including the following:

(1) The interference caused by leakage of the working power supply through the distributed capacitance and insulation resistance of the line; (related to the operating frequency)

(2) The signal is connected to each other through the impedance of the ground wire, the power supply and the transmission wire, or the mutual inductance between the wires. The anti-electromagnetic compatibility Sealing Joint For Armored Cable connector produced by Explosion Proof Cable Gland Supplier can eliminate the mutual coupling impedance well. To the role of anti-interference.

(3) Some components inside the equipment or system generate heat, which may affect the interference caused by the stability of the components themselves or other components;

(4) The magnetic field and electric field generated by high-power and high-voltage components affect the interference caused by other components through coupling.
