Wireless multiplexers – The wireless signal cable

Wireless multiplexers  

Transmit your I/O signals reliably to hard-to-reach or rotating stations using the Wireless MUX

The Wireless MUX can be installed very quickly: simply connect, switch on, and you have a working wireless path. The system transmits 16 digital and 2 analog signals bidirectionally. This means that it can replace a 40-wire signal cable.

  • Easy startup, as no configuration or settings are required
  • High number of channels in a compact housing
  • Fast connection establishment and signal transmission
  • Range of up to 200 m with omnidirectional antennas, up to 400 m with directional antennas with a clear line of sight
  • Current Bluetooth 4.0 technology
