What is M12 4 pole A coded connector ?

M12 4 pole A coded is M12 connector A coding type with 4 pins, it's circular waterproof connector which had been widely used for sensor connector cables in automation field. As we can see from the picture, M12 4 pole A coded could be different types M12 connector :

  • M12 4 pole A coded molded connector female or male
  • M12 4 pole A coded assembly connector male or female
  • M12 4 pole A coded square female socket
  • M12 4 pole A coded to RJ45 adapter
  • Straight molded M12 4 pole A coded plug
  • Back mount M12 4 pole A coded socket
  • M12 4 pole A coded Y type adapter
  • M12 4 pole A coded plastic assembly plug

There are other types M12 4 pole A coded connectors from different manufacture.

Difference between M12 4 pole A coded with B coded , C coded , D coded

M12 4 pole connector sorted by coding type, could be A coded , B coded , C coded and D coded , from the above pinout of M12 4 pole connector , we can see that connectors with different coding type couldn't mate with each other , as the pinout of the A B C D coding are different.

M12 4 pole A coded molded plug VS M12 4 pole A coded assembly plug

Advantage of molded M12 4 pole A coded connector

  • Pre-formed to reduce installation time
  • Injection molding with cable, avoid waterproof problems caused by poor assembly
  • More suitable for mass production and installation
  • More cost-effective than assembly in the case of large quantities

Disadvantage of molded M12 4 pole A coded connector

  • Long delivery time
  • Only with PA material housing, not strong enough for some application
  • Couldn't be repaired while have problem

Advantage of assembly M12 4 pole A coded connector

  • Could be installed in field, convinent and save time
  • Have PA housing or metal housing for option, could work for much worse environment
  • Could disassembly if wrong connected, save cost
  • Much fast and cost-effective for small quantity application
  • Save shipping cost, as the molded ones with cable is very heavy

Disadvantage of assembly M12 4 pole A coded connector

  • High labor cost especially for Europe countries and US
  • The waterproof protection may have problem if the assembler is not professional

Application of cable connector M12 4 pole A coded

M12 4 pole A coded belongs to M12 A code connector, the M12 A coding type have 2pin , 3pin , 4pin , 5pin , 6pin , 8pin , 12pin , 17pin for option , 4 pole A coded M12 connector is one of the most hot selling.

The A-coded M12 connector is the earliest developed M12 connector, and it is also the most widely used M12 connector.

The 4 pole A code M12 connector had been widely used power connect and industrial sensors, but as the rated current is not very big, the M12 4 pole A coded connector had been replaced by T coded M12 connector and K coded M12 connector.

PEPPERL+FUCHS Vibration Sensor Connector M12 4 pole A coded

The picture aboved shows PEPPERL+FUCHS Vibration Sensor which use M12 4 pole A coded connector to connect to the control system, beside PEPPERL+FUCHS, the other brand like OMRON , NXP , Rockwell , Cognex , IFM , Balluf ... all will use M12 4 pole A coded connector.

M12 4 pole A coded connector had been widely used for fieldbus, such as AS-interface , FOUNDATION Fieldbus, CC-Link.
