In the application of PLC Connectors products, contact performance is one of the most important parts. However, during the use of PLC Connectors, their contacts may be affected by some factors, thereby leading to the occurrence of some faults. The main problems that usually cause damage to the contact performance of PLC Connectors are as follows:
The contact corrosion problem of PLC Connectors
PLC Connectors need to be customized for use according to the different environments of the application industry. In some harsh working environments, PLC Connectors may be affected by certain special organic gases, thereby corroding their contacts. Corrosion and contamination will increase the resistance of the contacts. Thus affecting the electrical performance of PLC Connectors.
2. Arc corrosion problem of PLC Connectors
When the conductor is closed under high voltage and high current intensity, arc discharge occurs. The arc discharge generates instantaneous high temperature, which melts and vaporizes the metal surface of the contacts of the PLC Connectors and causes the contacts of the PLC Connectors to deform. When the arc discharge forms a plasma state, a layer of chemical film will cover the metal surface of the contacts of PLC Connectors. This uncontrollable chemical film is the main factor affecting the electrical performance of PLC Connectors.
3. Vibration issues of PLC Connectors
PLC Connectors often encounter the influence of vibration problems in practical applications. These vibrations cannot be detected by the naked eye, and the amplitude is usually at the micrometer level. There are many reasons for the vibration of PLC Connectors, all of which can cause wear on the contacts of PLC Connectors, lead to deformation, and ultimately increase the resistance between the contacts.
