Circular connectors for servomotors and power supply

Virtually conceived and now in real life: The M12 power connector with L-coding meets all market requirements. It is very small yet powerful, prevents mismating, is PROFINET-compliant. With M12L, sensor/actuator cabling as well as the power supply of smaller DC motors, e.g. in driverless transport systems, is successful.

  • Attachment housing G4 in combination with coupling plug F6.
  • Powerful up to 16 A despite extremely space-saving size for very small devices.
  • Mechanical L-coding of the mating face prevents mismating with mating connector.
  • Suitable for conductor cross-sections from 0.75 - 2.50 mm².
  • Available as 4-pole variant with black insulating body and as 4+FE variant with grey insulating body and functional earth contact (FE).

Application range

  • For DC applications in the low-voltage range.
  • For power supply of smaller devices (e.g. decentralised I/O modules, smaller motors).
  • Also suitable for power supply in the PROFINET network (M12L is considered the standardised power interface there).
