Signal devices manufactured ready-made with M12 plug.

M12 connection technology is a widely used standard in the industry.

Pfannenberg now offers a whole range of ready-made signal devices.

Optical signaling devices, sounders and combination devices in all performance classes as well as our signal towers and obstruction lights can now be integrated even faster with this connection technology in your systems.

The advantages of M12 connection technology are obvious:

  1. Increased machine and plant safety by avoiding wiring and connection errors, since the devices no longer need to be opened for assembly.
  2. Circuits do not have to be interrupted or switched off during maintenance, conversion or replacement of devices – this saves time and money.
  3. Assembly and set-up times are considerably shortened or simplified.
  4. Safety in connection technology is one of the most important criteria in plant engineering and mechanical engineering.
  5. M12 plug-in technology creates high flexibility and acceptance by the planner and user.

Standard PIN assignment

In addition to the supply voltage, which is available at PIN 1+ and PIN 3-, the external tone selection at PIN 2 and 4 can be used, for example, for devices of the PATROL series. With QUADRO devices, the operating modes can be controlled separately and with the combinations PA(X) series sounder and flashing light.
