M12 Connected Signaling

M12 connection technology is a widely accepted industry standard that provides a quick and easy way to integrate audible and visual alarms into your systems and applications with the plug and play technology.

Pfannenberg offers a wide range of M12 configured signaling devices including audible, visual and combined devices in all performance classes through our PYRA, PATROL, and INTENSE STACKLIGHT series.

Advantages of M12 Connection Technology:

  • Plug and Play – simply plug in your M12 cord set to use.
  • No electrician needed to wire the device.  Connection and DIP switches are already made.
  • Increased plant and machine safety with elimination of connection and wiring errors.
  • No need to interrupt circuits during maintenance, conversion, or replacement of devices – saving time and money.
  • Devices are pre-assembled – you simply mount the unit to your machine and plug in your M12 wire connection.

M12 Connected Signaling Product Features:

  • All PATROL & PYRA series lights use 4-Pin M12 connection. See diagram below.
  • All Intense BR50 series lights use 8-Pin M12 connection. See diagram below.
  • M12 is only used with low voltage DC power.
  • Audible devices offer 4 tones – with 80 tones to choose from
  • Combination units offer multiple tones/colors/frequency modes.

Typical M12 Connected Signaling Applications

Laser Cutting Machines:

Used for precision cutting, etching, or engraving.  Indication lights notify the operator if the machine is running or may need attention.  M12 connected signaling devices allow for quick, robust and accurate connections in a standardized format.

Industrial Robots:

Used to automate intensive or repetitive production tasks to ensure employee safety and it is important to have visual or audible signaling to notify staff of the status of the robots’s operation for both safety and operational performance requirements.  M12 allows for quick, robust and accurate connections.

Modular Manufacturing Systems:

Flexible, sub-processes that include mechnical and automation components. These modules can be easily integrated or interchanged, allowing for flexibility, scalability, and efficient assembly processes..  M12 connectors allow for quick, easy changes and updates by plant engineering.

CNC Machines: 

Pre-programmed, software used to control a wide range of complex machinery that requires indication alarming to notify staff of current state activities.  M12 provides quick connection without the need for rewiring.
