MUX has many different meanings depending on who you are and where you are from. Look it up, it is quite amusing.

For the purposes of this story we will use MUX as being short for MULTIPLEX.

In its simplest form, a MULTIPLEXER transfers an input signal form one controller to an output signal on another and in both directions.



At Phoenix Contact, we have a variety of multiplexer solutions for industry. You will be pleased to know we have kept it simple!  Our multiplexers save time and money by utilising either simple cabling or wireless media as a cable replacement with minimal effort.

Installed application examples are :

  • Networked multiplex utilising existing network cables to communicate between multivendor controllers
  • Lift cabling replacements
  • Crane cable replacement
  • Drag chain replacement
  • Slip ring replacement and many more including wireless safety.

This is how its done…
