Common Causes of Signal Interruption for M12 A-coded Connectors
Main Fault Causes & Analysis
-
Dust & Moisture Intrusion
: Dust and water vapor entering the connector interface causes pin oxidation and poor contact, resulting in intermittent signal or complete interruption.
-
Excessive Cable Bending
: Frequent excessive bending of the cable leads to internal wire breakage or poor connection of the core wire, which is a common hidden fault of the cable assembly.
-
Loose Interface Caused by Vibration
: The connector is not fully tightened during installation, and the interface becomes loose under industrial vibration working conditions, leading to poor physical contact.
-
Improper Core Count Selection
: The selected core count specification exceeds its rated current load, which causes abnormal heat generation and unstable signal transmission of the connector.
Technical Note: Regularly clean the connector interface and check the cable integrity, ensure the connector is fully tightened during installation, and select the appropriate core count according to the actual current demand to avoid signal failure.
