M12-Ready Configured Signaling Solutions

Pfannenberg, Inc.'s full product range of audible, visual, combination, and stacklights are now available with M12 readiness.

M12 technology removes the need for an electrician or electrical installer to wire the device as the connections and DIP switches are already made. A traditional install may take an expert 5 to 10 min. per device, while an M12 connection can be made in 30 seconds with no electrical expertise. And, since the device doesn't have to be opened during installation, wiring and connection errors are avoided. Finally, the connection can easily be undone which means power does not need to be turned off to the system to perform maintenance, saving time and money.

With the addition of an M12 cord set, Pfannenberg’s signaling devices become plug-and-play ready for low voltage, 12 or 24V DC, applications.

All Pfannenberg M12 compatible signaling devices are pre-assembled and wired for quick installation; you simply mount the device to your machine and plug in your M12 wire connection. Pfannenberg’s M12 connectors offer Pin compatibility and flexibility allowing the devices to be set up to suit the precise signaling needs of the customer.

The full range of M12 compatible devices includes the PATROL series sounders, PYRA flashing, and LED lights, combined devices with flashing lights and sounders, and INTENSE BR50 stacklights.

For PATROL and PYRA sounders and flashing lights, the M12 connections are all 4-pin while the BR50 stacklights are 8-pin connections.

The PATROL sounders and combined audible devices offer 4 tones in the M12 compatible versions with 80 tones to choose from. The combination devices also offer multiple tones, colors, and frequency modes for each device. The BR50 M12 devices control each individual module stack.
