Contactors play a vital role in industrial automation

The contactor in industrial automation is an important control component. Let’s introduce it to you today!

Contactors play a vital role in industrial automation. They can control the opening and closing of circuits and realize automatic control of equipment.

The working principle of the contactor is to control the opening and closing of the contacts through the attraction and release of the electromagnet, thereby realizing the connection and disconnection of the circuit.

Contactors generally consist of contact systems, arc extinguishing devices, magnetic systems, brackets and bases.

The contact system is the actuator of the contactor, responsible for connecting and disconnecting the circuit;

the arc extinguishing device is used to eliminate the arc generated when the contact is disconnected and ensure the good operation of the contact;

the magnetic system is the control part of the contactor, consisting of It consists of a coil, an iron core and an armature, which are responsible for generating magnetic force to attract the contacts;

the bracket and base are the support structures of the contactor and are used to install other components.

The main technical parameters of the contactor include rated voltage, rated current, action value, pull-in time, release time, etc.

In practical applications, it is necessary to select the appropriate contactor according to the needs of the equipment, and operate and maintain it in strict accordance with the instruction manual.

Contactors are indispensable control components in industrial automation. I hope that through today's introduction, everyone can have a deeper understanding of contactors.
