Its small size makes the M12 Power Connector suited for applications with little free space, like automotive, manufacturing, machine building and power transmission.

This low-maintenance connector is reliable, installation friendly, and available in both male and female connectors. Its compact design and high power transmission make it a cost-effective solution for operations that need a reliable, flexible connector.


  • Outstanding performance in power transmission while fulfilling global standards (UL, VDE); designed according to DIN EN 61076-2-111

Operational reliability

  • transmitting high power even at high ambient temperatures; higher derating grants maximum uptime in production


  • a wide range of codings (S-, L-, K- & T-) molded, attachable and receptacle, combined with a strong diversity of cables; an ideal solution for nearly all markets and applications

M12 Power Technology in four different codings fulfill the needs of several applications.

All M12 Power Connectors are designed for permanent usage, even within harsh Environments with high temperatures and in demanding applications.

The M12’s K- and S-codings are designed for AC power supplies with 630 V AC/16 A, making it the ideal solution as a power connection for AC motors and drives, frequency inverters, motor control switches, auxiliary power distribution for control systems and direct wiring of LED and conventional lighting fixture systems.

The L- and T-coding versions are designed for DC power supplies with 63 V DC/16 A, which works well for low-voltage applications, such as power supplies for fieldbus Ethernet components, network devices, motors and drives and direct wiring of LED and conventional lighting fixture systems.


The M12 Power Connector features the well-known and proven Lumberg Automation M12 technology, meeting all the requirements for higher power consumption of control, sensing and actuators in automation control systems.


The M12 Power Cordsets come with M12 shielded or unshielded connectors, with threaded joint and molded cable, knurled nut with self-locking threaded Joint

M12 Power Field Attachable Connectors: Shielded or unshielded with self-locking threaded joint and knurled nut.

Four different codings fulfill the needs of several applications, while preventing mismatching connectors with different voltages.
