Optical data transmission

Data within a network is transferred in different ways. Optical data transmission photoelectric sensors use the "air" medium to transfer data invisibly, contact-free and free from wear over a distance of up to 300 m. This is a leading technology in plant engineering and combines efficiency with cost effectiveness.

Overview

Optical data transmission

Data within a network is transferred in different ways. Optical data transmission photoelectric sensors use the "air" medium to transfer data invisibly, contact-free and free from wear over a distance of up to 500 m. This is a leading technology in plant engineering and combines efficiency with cost effectiveness.

DDLS 500

Optical data transceiver with integrated web server for remote diagnostics

Optical data transceivers are the right choice for any application where data needs to be transmitted without cables and without interference. They enable contact-free communication wherever mechanical and WLAN systems are pushed to their limits.

The DDLS 500 optical data transmission photoelectric sensor enables the transparent, contact- and wear-free transmission of data over distances of up to 200 m in 100 Mbit/s real-time. To this end, an invisible, infrared laser communicates bi-directionally between the devices. Additional functions simplify handling of the devices. With the aid of the laser alignment aid and the integrated level, alignment is very simple, even over longer paths. Unique worldwide, the web server integrated in the DDLS 500 enables remote diagnostics. Furthermore, the DDLS 500 can be detected as a PROFINET participant.

Advantages for you

Transparent real-time data transmission: With 100 Mbit/s, all common Ethernet protocols can be transmitted with minimal time delay.
Integrated connectivity: Worldwide access to all diagnostic data via an integrated web server. Transfer of diagnostic data to the control (PROFINET).
Combine functions yourself: The modular design allows the base model to be freely expanded with the available functions: operating range, laser alignment aid, heating and web server.
Simple mounting and alignment: The laser alignment aid, the spirit level and the integrated mounting plate with alignment screws make mounting and alignment extremely easy.
Continuous monitoring of the received signal level: Enables the user to be alerted in good time to an impending failure (e.g. as a result of excessive soiling).
