Data transmission

Product selector

Contact-free transmission of information by means of infrared light

Whenever data needs to be communicated without contact, optical devices for data transmission are the right choice. The optical data transceivers are used primarily in plant engineering, especially in applications where industrial networks such as PROFINET, PROFIBUS, DeviceNet or Ethernet etc. are connected to system components which are moved.

DDLS 500

Product selector

Data transmission photoelectric sensor with 100 Mbit/s real-time transmission

The DDLS 500 is a data transmission photoelectric sensor that, in addition to a high transmission rate of 100 Mbit/s, sets new standards – above all with respect to usability. The location-independent remote diagnostics function via integrated web server or direct connection in PROFINET is unique worldwide.

  • Ranges up to 200 m possible
  • 100 Mbit/s transparent data transmission of all Ethernet protocols such as PROFINET, EtherNet IP, EtherCat, etc.
  • Laser alignment aid
  • Monitoring of availability
  • Interference-free parallel operation with AMS 300i
  • Integrated "one-man" alignment device
  • Optionally with heating (as low as –30 °C)
  • PROFINET participant
  • Remote Control


DDLS 200

Product selector
